Glue is a material of fundamental importance for those who work with wood, but there are significant differences between that used in the professional field and that usually used at a hobby and amateur level.
In the buying guide we will go further into the subject, describing the various types of glues and their specific characteristics; Our ranking, on the other hand, examines in detail the most requested wood glues on the market, regardless of their intended use.
In the first places there are two products of the well-known German company Fischer, appreciated above all in the professional field; the Mega Glue , a perfect two-component epoxy adhesive for use on wood in exterior and repairs, and SG20, a classic quick-setting glue ideal especially for small home repairs.
8 Best Wood Glues for Furniture [2022 Updated ]
In the first places there are two decidedly expensive wood glues with excellent yield; in the ranking there are also cheaper products for domestic use and specific glues for carpentry.
1. Fischer Mega Glue 552153 NTJH extra strong two-component glue
The German firm Fischer is known for being one of the global leaders in the production of fastening systems, so it is not surprising that Mega Glue is considered one of the best wood glues of 2021 and that it is one of the best-selling products online.
It is a two-component epoxy adhesive whose formula is specially designed for fixing high loads, both indoors and outdoors; in fact, once dried it is resistant to water, vegetable and mineral oils, diesel, petrol, dust, acids, diluted alkalis and other diluted chemicals, as well as a great variety of solvents, even if subjected to long exposures.
It is able to firmly bond not only wood, but any type of material except for polyethylene, polypropylene and PTFE. The only flaw of the Fischer glue, however, is that it is very expensive.
Strong grip: Fischer two-component glue is ideal for gluing heavy wooden elements, as its formula is specially designed for securing heavy loads both indoors and outdoors.
Easy to apply: The tube is divided into two sections in order to allow a perfect mixing of the two components, as well as facilitating the correct dosage and therefore avoiding unnecessary waste.
Workable: The setting time is about 6 minutes, therefore it allows to carry out any corrections; moreover, once dry, it can be safely sanded to remove excesses and then painted.
Expensive: The only flaw is represented by the high cost, which in any case is proportionate to the quality of the product; it is especially recommended for professionals and the most demanding.
2. Fischer SG20 Instant Adhesive ultra fast glue
Professionals and hobbyists alike are enthusiastic about the Fischer SG20 and, in their opinion, it is the best wood glue available on the market compared to all those with an ethyl cyanoacrylate formula.
SG20, in fact, is an ultra-fast instant glue with high resistance and toughness, especially ideal for gluing regular surfaces such as plastic, rubber and metal, but also excellent for wood and other materials. Its liquid consistency allows it to penetrate into the smallest cavities; the setting time is just 30 seconds if applied in thin layers. The high gripping speed, however, requires the utmost precision in positioning the parts to be glued.
The performances offered by the Fischer SG20 are of a high level, of course, so also in this case we are faced with an expensive product, suitable for DIY but appreciated above all by the most demanding user group.
Quality: The German company Fischer is one of the global leaders in the sector of fastening systems, and its adhesives are universally known for their high quality and high efficacy; it is no coincidence that they are the most used in the professional field.
Ultra fast: SG20 is an ethyl-cyanoacrylate based glue, therefore its main feature is the setting speed; the thinner the applied layer, the faster it dries and adheres to surfaces.
Effectiveness: In addition to its toughness, it also stands out for its high resistance over time; if you need a glue that once applied lasts a long time, then this is the ideal solution.
Expensive: Also in this case the only limitation is given by the high price but considering the quality of the product it is completely understandable.
3. Bostik Max Repair D2258 transparent universal glue
If you want to know where to buy a wood glue that is effective but available at low prices, then we suggest the Max Repair produced by the well-known brand Bostik, which in turn belongs to the Italian multinational Bolton Group.
Max Repair, in fact, is the cheapest product examined in our ranking, and is a universal adhesive specific for hobby use and do-it-yourself in general; moreover, as the name suggests, it is especially suitable for indoor and outdoor domestic repairs, thanks to its remarkable resistance to water, humidity, UV rays and extreme temperatures.
Thanks to the low and easily accessible price, Bostik Max Repair is widely used but, as previously mentioned, it is used exclusively in the home; the quality and yield of this glue, in fact, is of medium level and over time tends to peel off.
Price: This is the cheapest glue among all those we have examined in our ranking; and of course it is only recommended for amateur and domestic use.
Wood: Although it is proposed as a universal adhesive, the best yield and adhesive effectiveness of Max Repair glue are obtained above all when it is used for wood. For all other materials, however, it is less performing.
Packaging: It is available in both 20 gram and 8 gram packs; in this way it is possible to choose the one that best suits your needs, thus avoiding the risk of unnecessary waste.
Average quality: The duration of its effectiveness is limited compared to the more expensive glues, and over time it tends to peel off; moreover, if not consumed, it dries up in the tube.
4. Pattex Millechiodi external and internal extra strong adhesive
Here is another product that will not sound new to DIY enthusiasts: the famous Millechiodi produced by the well-known brand Pattex, owned by the German chemical company Henkel.
Millechiodi is especially appreciated as a glue for wood for exteriors and interiors, even if its formula is specifically designed to be used in the assembly of a wide range of materials: metal, ceramic, glass and plastics, with the exception of polyethylene, polythiophene. and teflon. It is mainly used as a glue for wood and metal for outdoor use, thanks to its impermeability and excellent resistance to humidity and temperature changes, but always mainly in the hobby field.
The only flaw is that its adhesive power loses its effectiveness depending on the combination of materials to be glued, for example it is not very suitable for fixing wood directly on plaster or on plastered surfaces; on the other hand, it works much better when you have to glue wood on wood.
Convenient: Both the quality-price ratio and the quantity-price ratio are both decidedly favorable; obviously it is available in different formats, from 100, 340 and 450 grams, according to the needs.
Excellent for outdoors: It is a wood glue resistant to water, humidity and temperature changes, so it is especially recommended for repairs and external assembly.
Easy to apply: The 450 gram cartridge has a spout and is made to be used with the same guns used for silicone cartridges; which makes it easy and practical to use.
Surface compatibility: Pay attention to the type of applications, because its adhesive power loses its effectiveness when trying to glue different types of materials.
5. WFix Der Starke D3 water resistant wood glue
Der Starke D3 is a quick glue for wood produced by the German brand WFix, ready to use and easy to use, once dried it is colorless and is able to resist water and atmospheric agents.
Except for the setting time, which is faster, Der Starke is a vinyl-based glue, which makes it particularly suitable for all wood materials and especially for parquet and laminate; the bottle with spout also makes it extremely easy to apply and allows you to dose it effectively, in order to avoid unnecessary waste.
Once dried, it offers a firm hold and its resistance to low and high temperatures is also ideal for bonding wood outdoors; the only flaw is that once the bottle is opened, it must be consumed within a year, otherwise the glue will dry.
Fast setting: Despite being vinyl based, Der Starke is characterized by a decidedly faster setting time, even complete drying takes less time.
For wood: It is suitable for all types of wood, including glulam, masonite and MDF, but is especially suitable for panels, laminates and parquet; it is applied directly to the surfaces to be bonded and once dry it becomes colorless.
Resistant: Once completely dried, it resists water, humidity and low and high temperatures, so it is suitable for fixing wood both indoors and outdoors.
Quantity: The smallest package contains 250ml, so it is only recommended for hobbyists who work with wood and can use it regularly.
6. Elephant Elevil 2252 D3 vinyl glue for wood
The one produced by the Messina company Elephant is also a vinyl glue with a D3 resistance classification, therefore resistant to water and humidity; it is a relatively new product on the market, but which has already entered into direct competition with the other vinyl glues available on the market and produced by the most famous brands.
Its characteristics of resistance and sealing, in fact, have nothing to envy to those of the most famous glues. Its consistency is slightly more full-bodied than the standard average of vinyl adhesives, but the setting is not immediate and this allows a certain margin of workability; Once it dries completely, however, it offers a solid and extremely durable grip.
The Elevil 2252 in a 5 kg pack, however, is convenient only for carpenters and hobbyists; even though it is a D3 vinyl glue, once dry it hardly tolerates direct and prolonged contact with water.
Excellent for carpenters: Apart from the 5 kg format, which requires intensive use, the Elevil 2252 is especially recommended for carpenters and hobbyists who work mainly with wood.
Ideal for panels: Its characteristics make it particularly suitable for making laminated panels and strips for furniture, walls and floors, for fixing decorative plastic sheets on wood and for frames, doors and windows.
Resistant: Once dried and hardened it becomes extremely resistant and offers a very firm grip; Elevil 2252 is rated D3, but can be increased to D4 by mixing it with Elephant 1030 hardener.
For interiors only: Unfortunately it tends to melt if exposed to direct contact with water for prolonged times, so it is only recommended as an interior wood glue.
7. Vinavil 59 vinyl glue for wood 1 kg jar
For the vinyl glue Vinavil 59 no presentations would be needed, it is in fact the most famous brand in Italy, and it is one of the most widespread wood glues in both professional and amateur fields.
Vinavil 59 is mainly used in the production of plywood, laminated and blockboard panels, for gluing wood to plastic and for veneers; but it is also commonly used for the assembly of frames, doors, furniture and other elements or objects in wood. Apart from the reliability of the historic brand, it is also appreciated for its effectiveness and excellent value for money.
The only flaw, in this case, consists in the fact that the 1 kg jar is only suitable for those who use it with a certain regularity; for home use it is preferable to buy a vinyl glue sold in small bottles, so as not to run the risk of wasting it due to inactivity.
Reliable: Vinavil is the most famous Italian brand when it comes to vinyl glues, and is also considered the most reliable; it is no coincidence that it is the favorite of carpenters and craftsmen who work with wood.
Effective: Once hardened, it offers an excellent and above all long-lasting grip; complete drying, however, requires more than 12 hours to ensure maximum effectiveness.
Ideal for wood: Vinavil is considered the glue for wood par excellence, as it is suitable for a wide range of applications starting from the production of panels and laminates up to the gluing of furniture and objects, even of different woods.
One kilogram: The quantity-price ratio is good, but if you don’t use it often it will get annoyed and go to waste; the one kilo pack is recommended for intensive use only.
8. Bostik Wood PU Professional bottle 250 grams
We conclude our ranking with another product appreciated mainly in the professional field, the PU Wood produced by Bostik. It is a polyurethane glue for wood, so it is able to set in much faster times, about 30 minutes, but for complete drying it takes a much longer time than vinyl glue, which can even reach more than 30 hours; its classification is higher however, D4 instead of D3, so it is a wood glue that has an exceptional level of strength and toughness.
Bostik Wood PU is particularly suitable for outdoor use, because its high resistance also extends to atmospheric agents and water, it is also excellent for bonding wood exposed to the marine environment, therefore for repairing boats and fishing equipment. . However, due to the high cost and difficulty of use, this glue is only recommended for professionals.
Extra Strong: The polyurethane glue for wood is the one that guarantees the greatest effectiveness in terms of tenacity and resistance of the bond; even the initial setting takes place relatively quickly.
Class D4: Its high resistance to water and atmospheric agents is such as to make it ideal above all for bonding external wood and that exposed to the marine environment; in fact it is widely used for the repair of fishing rods and boats.
PU: The polyurethane technology on which this glue is based makes it suitable not only for wood but also for gluing polyurethane objects, including foam.
Difficult to use: Polyurethane glue tends to expand during drying, so it requires the experience of a professional to use; it is also very expensive.
How to choose the best glues for wood
Only an experienced carpenter could know which wood glue to buy according to different needs; for the benefit of novice DIY enthusiasts, therefore, let’s examine in detail the various types of glue available on the market.
The chemical composition and specific characteristics
To understand how to choose a good wood glue, you must first distinguish between the different types that exist, which differ according to their chemical composition. Each type of glue, in fact, has certain characteristics that derive precisely from the chemical substances that compose it; some have an immediate setting time while others leave a certain margin of “workability”, some are water resistant, others are not, and so on. Certain glues for wood, therefore, can be more or less useful depending on the applications for which they are intended.
In the home, for example, universal glues are very common; these have a setting time ranging from about 30 to 60 minutes, therefore they offer a good margin of time to make corrections in the positioning of the pieces to be glued; even those with ultra-fast setting are suitable for domestic repairs but, precisely because of this characteristic, they require greater attention and precision in handling the pieces to be joined.
The vinyl wood glue, on the other hand, is widespread both at home and at an artisanal and professional level, while the aliphatic wood glue is characterized by a higher cost and is used purely in the professional field.
The epoxy glue
This type is especially suitable when it is necessary to carry out renovations or repairs on wooden elements; epoxy glues, in fact, are characterized by a high resistance and an adhesive power capable of withstanding high weight loads.
Being made up of two distinct components to be mixed together at the time of application, however, they require particular attention in being handled; they are also distinguished by a higher cost than that of other wood glues, including even aliphatic which is notoriously more expensive than vinyl.
Epoxy is also subject to strict precautions for use, so it is absolutely not recommended for home use; for repairs and general home use, in fact, it is better to focus on a universal glue on the vinyl glue, which are easier to use, harmless to health and far cheaper.
The resistance classes
Another important aspect that must be taken into account when choosing a wood glue is their performance classification according to the DIN-EN 204, DIN 4102 and WATT 91 standards; this aspect is particularly important as some wood glues are water resistant and others are not, and the same is true for resistance to heat and traction.
The legislation establishes four distinct classes: D1, D2, D3 and D4; the glues belonging to the D1 class are suitable for gluing the wood of furniture and internal artifacts, not exposed to substantial variations in temperature and humidity, while the D2 are resistant to humidity and occasionally also to water, therefore they are suitable for glue the wood of furniture or elements located in bathrooms and kitchens.
For wood exposed outdoors or in particularly humid environments, however, it is advisable to use a classified D3 glue; the D4, on the other hand, are particularly suitable for outdoor use, for the nautical sector and in all those contexts subject to critical climatic conditions.
How epoxy wood glue works
The “syringe” packs
The epoxy wood glue can be easily distinguished from the others because it is sold in a particular package consisting of two coupled syringes, filled with the relative components, whose plungers are fused together in such a way as to allow the components of the glue to be extruded in proportions the same during application.
This particular solution is due precisely to the fact that epoxy glues are made up of two distinct components: A and B; component A is the base resin while component B is the hardening catalyst. In order for the glue to harden and set, the two components must first be mixed together.
The mixture and the reaction
When components A and B are joined, therefore, they give rise to a cold reaction called polymerization, during which the glue solidifies to a glassy and shiny consistency. Once hardened, the epoxy takes on a transparency and gloss very similar to that of glass, and it becomes extremely resistant to traction, heat, water and humidity.
The applications of epoxy glue
Thanks to its particular qualities of mechanical and chemical resistance, epoxy wood glue is used above all for bonding outdoors, for use in a marine environment and when particularly heavy elements must be fixed and it is not possible to use pins or other systems. analogues.
Disputes regarding its potential harmfulness
Most of the resins and epoxy glues used today are obtained starting from epichlorohydrin and bisphenol A; the latter substance, also commonly known as BPA, is at the center of numerous controversies as scientific studies have amply demonstrated its role as an endocrine disruptor, and consequently its deleterious effects on the health of humans and animals. In particular, BPA has been found to cause neurotoxic and carcinogenic effects, and for this reason it has been banned from most commonly used products.
Unfortunately, its presence in epoxy glues is essential, which is why in 2008 the European Union established that these substances in particular, if used correctly, are to be considered safe for consumers and the environment.
By “correct use” of epoxy glue we mean the use of all those precautionary measures aimed at avoiding direct contact with the substance and its fumes, as well as its dispersion into the environment; when working with epoxy glue, therefore, it is vital to use gloves, goggles and a protective mask for the respiratory tract, avoid direct contact with the skin and ensure that the glue does not drip on the ground; after use, the remaining residues must be carefully cleaned and disposed of as required by current regulations.
How many types of wood glue are there?
There are different types, some with fast and ultra-fast setting, such as cyanoacrylate, and others that take longer to dry but offer a high adhesion power, such as vinyl glue, aliphatic and epoxy. In the professional field, vinyl, aliphatic, epoxy and polyurethane glues are mainly used, which are classified D3 and D4 according to DIN-EN 204.
Which glue for wooden baseboards?
One of the favorites for installing wooden skirting boards is assembly glue, such as the Mille Chiodi produced by the Pattex brand for example. You can also use other solutions of course, such as neoprene glue or double-sided tape, but assembly glue remains the most popular as it takes some time to set and therefore offers a good margin of time to correct any positioning errors of the baseboards.
How much does wood glue cost?
The price varies mainly based on the quantity contained in the package, and can range from 3-4 euros for small bottles of 100 grams or less up to 200 euros and over for 30 kilogram buckets.
Obviously, the type of glue also affects the price; epoxy, polyurethane and cyanoacrylate, for example, are the most expensive of all, closely followed by aliphatic glue. The latter is a fairly high-cost wood adhesive because it offers a higher yield than that of vinyl glue, moreover it is also characterized by the classification D4, therefore it is placed at the top of the performance classification traced by the EN 204 standard and consequently it is used mainly in the professional field.
