How to use PU Wood Adhesive
In order to use PU wood adhesive, there’s a simple process you’ll need to follow. We’ve detailed it below & included a video to make the process as easy as possible.
PU adhesive can be used to bond all timbers (wet & dry) as well as concrete, polyurethane foam, expanded polystyrene, and other porous and non-porous materials.
The advantages of PU adhesives are that they are:
- Thixotropic – they stay where you put them causing less mess
- Rapid curing – this means less cramping time & it saves labour costs
- Easy to use – they often come in cartridges that can be inserted into a mastic gun to make application easy
- Temperature resistant – the adhesives can be used near ovens & light boxes
- Flexible – their curing time means that they can be adjusted whilst assembly is happening
We have used our own Wood Weld PU Adhesive but others are available.
You will need:
- Timber cramps
- PU adhesive
- A timer
The process is extremely simple. We have split it out into 8 steps but it can be completed very simply in a matter of minutes:
- Prepare the cartridge by cutting of the top with the Stanley knife
- Place the cartridge in a mastic gun
- Prepare the items to be bonded
- Squeeze out the PU onto one of the pieces that is to be bonded
- Clamp the wood together
- Wait for 10 minutes
- Remove the clamps & test the joints
- Cut off any excess material
To make it easy, we have included our video below detailing these steps:
