Warmshell Board Adhesive is a breathable, moisture-wicking adhesive for fixing Warmshell insulation boards to porous backgrounds.

It has a high lime content, which acts as a natural biocidal and compliments the rest of the Warmshell system helping keep walls dry. Careful choice of ingredients omits toxic or persistent biocides and the adhesive has extremely low VOCs.

Limegreen have designed this product carefully so that it contains 99% lime and sand, while still providing enough stickiness. The high mineral content offers better protection from rot or fire than most polymer based adhesives. It also acts as an active moisture-wicking layer, making sure any moisture in your wall doesn't get trapped.

PLEASE NOTE Warmshell Board Adhesive is not for use as a tile or stone adhesive, nor for application to waterproofed backgrounds. When used to fix External Wall Insulation (EWI), mechanical fixings should also be used to resist wind loads.


Colour 

White to off white 

Packaging 

Available individually in 20kg bags, there are 48 bags on a pallet. 

Storage 

Store in a dry place free from damp and drafts. Shelf life is 6 months when stored correctly. Use within 24 hours once open.  

Coverage 

One bag covers approximately 2.5m2 applied with a 10mm notched trowel.  


Preparation 

Work in temperatures of 5°C to 25°C.  Backgrounds should be reasonably flat and straight and must be porous: apply an undercoat of Lime Green Duro if necessary. For other substrates check compatibility before commencing work. Ensure surfaces are free from dust and contamination. Do not apply to wet or contaminated backgrounds.  

Mixing

Add approximately 4 ¼ litres of clean water per bag and mix with a paddle in a bucket until a creamy consistency is reached. If a skin forms over the adhesive due to drying out or high temperatures it should be disposed of. Once mixed use within an hour.

Application

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. Aftercare:  Allow to cure for a minimum of 3 days before surface dressing.  Cleaning & Disposal: Clean tools and mixers with clean water. Hardened mortar can be removed with careful application of brick acid. Dispose of waste in accordance with local regulations. Un-hardened plaster is classed as hazardous and non-hazardous once set and dried. Safety Wear PPE when mixing and applying.
