Gluing instead of nailing (or screwing)

Wood is one of the most widely used materials in building, living and DIY.

Joining techniques using screws and nails are quite common and depending on the application, have their justification. However, the time-saving alternative of "gluing instead of drilling" is often an option.
Appropriate assembly adhesives can provide advantages over traditional methods, especially for flat applications and light objects such as wooden panels, skirting boards, etc.
Here, adhesives are the perfect solution for fixings without mechanical fixings.

The adhesive should be able to soak into the substrate and cross-link there, so that stability is created. This works quite well with porous substrates that are absorbent on both sides such as wood, e.g. wood on wood or plaster, but it's difficult to do with smooth substrates such as glass and tile - especially if the contact surfaces are small.

Suitable adhesives for wood bonding

Two-component adhesives are generally good to use when bonding wood to a material with a solid surface, such as metal, ceramics, or plastic.
A good wood adhesive absorbs the resulting shear and shear stresses from the different material joints well to a certain extent. This is especially true for epoxy resin adhesives. In addition, these usually do not contain any components that have a swelling effect on wood, such as parquet wood.

For bonding wood with metals such as steel, aluminium, copper, plastics, glass, stone or ceramics, for example, the 2-component construction adhesive Scotch-Weld 1838 B / A was developed on an epoxy resin basis. This product has a very long working time and is characterised by high shear strengths and good ageing properties.

Bonding glass to wood

Glass and wood are two extremely different materials: one smooth and with a compact surface, the other absorbent and with numerous pores.
To glue clear glass to wood, a transparent mirror adhesive is required. It's important to make sure that no bubbles or streaks are created when gluing. Although wood and glass can be bonded using assembly adhesives, such adhesives are usually white in colour, which causes problems when bonding clear glass.

Professional tip:
Transparent adhesives and glass have different light refraction, so you will still notice the bonding at a certain angle. It's therefore advisable, if possible, to paint one side of the clear glass before bonding to wood.

Double-sided high-performance adhesive tapes are also ideal for bonding transparent materials such as glass to painted wood, both indoors and outdoors. These include the acrylate-based VHB adhesive tapes 4905, 4910, 4915, 4918 from 3M.

3M™ VHB™ 

The foamed 3M Scotch Mount mirror tape is particularly suitable for attaching mirrors to furniture or doors. This is an ageing-, UV-, temperature- and solvent-resistant mounting tape for the furniture industry, shop fitting, exhibition stand construction and interior design. Scotch Mount adheres to wood, glass, metal, stone, ceramics and plasticiser-free. The plus: The foam is able to compensate for minor irregularities in the adhesive surfaces (up to a maximum of half the thickness of the adhesive tape).

Processing:
In general, adhesive surfaces must be clean, dust-free, dry and firm. Bonding to wallpaper is not recommended. The adhesive tape should first be applied to the substrate if the adhesive surfaces are uneven. It's best to apply the adhesive tape in a vertical direction because this allows the air to circulate better behind the mirror or metal panel.

Professional tip:
Neither double-sided adhesive tapes nor the mirror tape are, however, suitable for bonding solid glass, metal or plastic elements to unsealed, raw wood or even chipboard. Such joints would not last too long because wood fibres can detach from the bond and with them the adhesive tape from the wood. For this reason, it's essential to pre-treat wood surfaces appropriately before gluing (for example, with deep primer) or to screw on a metal sheet as a support for the adhesive tape.

Gluing parquet, laminate or tiles to wood or chipboard

Chipboard made of wood is a common material for quickly and practically forming a laying base for floor coverings such as parquet, laminate or plank flooring.
When laid directly on concrete, chipboard can be used as a substitute for the usual wet screed. However, wood chipboard is subject to dimensional changes. The wood swells or shrinks due to the seasons. The choice of an elastic impact sound insulation in combination with a flexible adhesive is therefore important.

For this purpose, there are e.g. partly solvent-based one-component or two-component adhesives on the market that are suitable for gluing parquet. The advantage of polyurethane adhesives is that they usually do not contain any components that have a swelling effect on parquet or floorboards. In the case of 2-component products, however, at least one component usually contains hazardous substances that require appropriate occupational safety measures.

1-component polyurethane adhesives (PUR), for example, cure due to ambient moisture and lead to softly elastic, but nevertheless very strong bonding of wooden boards, but also on gypsum boards or steel or aluminium substrates. One-component polyurethane adhesives, however, only reach their final strength after one to three days.

Polyurethane adhesives (2-component) are also suitable for bonding large areas of wood or plastic laminates. They cure by chemical reaction of two substances and offer high flexibility even with metal and plastic substrates. However, 2-component PUR adhesives require exact adherence to the prescribed mixing ratio as well as very careful mixing. Due to the limited pot life, they require particularly good work preparation, e.g. with regard to parquet cuts.

Reaction resin adhesives for parquet based on epoxy resin are only available as two-component systems. The technical properties are similar to those of 2-component polyurethane adhesives.

Professional tip:
Air bubbles are a weak point in the cured adhesive joint. Therefore, do not mix in too much air when mixing.
To keep the pressure on the glue joint constant, it's advisable to use screw clamps whenever wood is glued.
To ensure that bonded wood parts withstand the weather, PUR-based thermosetting adhesives are often the better choice, as they are also more heat-stable and therefore safer.

An effective two-component acrylic adhesive, especially for the wood trade, is Scotch-Weld DP810 from 3M - it's a fast-curing, solvent-free construction adhesive (processing time around 10 minutes). The integrated EPX system automatically mixes base and hardener in a 1:1 ratio from a double cartridge. Advantage: Dosing, mixing and application take place in a single operation. DP810 achieves very good peel, shear and impact strengths of wood on ceramics, metals or plastics with only a slight surface preparation.

For smaller surface bonding of wood, for example, the reactive polyurethane hot melt adhesive 3M Scotch-Weld 031 is suitable. This flexible product with a short bonding span is characterised by rapid strength build-up and high constructive final strength. Scotch-Weld 031 also bonds wood to plastics such as PA, PC, PMMA etc., as well as to fibre composites, rubber, textiles and leather.

For wood bonding, superglue also delivers what its name promises.

These adhesives are particularly suitable for small bonding areas and when no fixation is possible. However, because of the fast curing, large-area application is not possible. E-type cyanoacrylate adhesives from 3M's Scotch-Weld range are preferably used for bonding porous materials such as wood to cork, but also to metals and elastomeric plastics.

The Scotch-Weld activator for cyanoacrylate adhesives accelerates the curing process and allows bonding on less adhesive-friendly materials such as wood, but also cork.
