Warmshell Board Adhesive
Breathable mineral adhesive for Warmshell insulation boards
Breathable, moisture-wicking adhesive for insulation boards in the Warmshell range, including woodfibre, woodwool, graphite EPS and XPS Plinth board.
Warmshell Board Adhesive is a breathable, moisture-wicking adhesive for Warmshell insulation boards applied to porous backgrounds. With a high lime content, it has natural biocidal properties and works with the rest of the Warmshell system to help keep the wall dry. Careful choice of ingredients mean that our adhesive does not contain toxic or persistent biocides and has very low VOCs.
We've designed this product carefully so that it contains 99% lime and sand, while still providing enough stickiness. That means it is much safer from rot or fire compared to most polymer based adhesives. It also means it acts as an active moisture-wicking layer, making sure any moisture in your wall isn't trapped.

Application Guide
For use in the Warmshell Insulation System
Ensure the substrate is cured and hardened before starting. The substrate must not be saturated, but if it is extremely dry it can be lightly wetted before starting with a light mist of clean water. Apply Warmshell Board Adhesive with a notched trowel to the entire back of the board, combed so the direction will be vertical once the board is fitted. Various notched trowels may be used. If the background is not sufficiently plumb the wall can be back buttered as well. Starting from the bottom, firmly push the boards against the wall to collapse the bed of adhesive. As the adhesive is squashed in ensure full coverage is achieved, with no air gaps. Leave to set and harden well before undertaking further work.
