Wallrock Dampstop Thermic is an advanced, high-performance solution that simplifies damp-proofing. This updated version of our original Wallrock Dampstop eliminates paper and tar, providing a cleaner, more efficient approach at an exceptionally competitive price.

Rather than using paper based material, Wallrock Dampstop Thermic utilises a very tough, strong, rot proof and salt resistant polypropylene backing that will give a long service life even in very challenging conditions, bonded to a water resistant composite metallic barrier.

Each roll covers 5 square meters and is supplied in extra wide widths of 675mm to make containment of damp problems easier.

The rot proof backing can be applied directly to the wall with our Wallrock Dampstop Thermic Adhesive, effectively blocking off the appearance of unsightly penetrating damp and staining. The metallic surface can be overhung with one of our thermally efficient wallcoverings, Wallrock Fibreliner or decorative non-woven paper - we strongly recommend that Wallrock Dampstop Thermic Adhesive is used for further decoration for the best results.

So, why Dampstop Thermic?

Not only does it stop the unsightly damp and associated stains, if the composite, thermic, metallic surface is left exposed, it will also greatly enhance the reflection of heat into the room - making the product especially useful in improving energy efficiency in the home when used behind radiators and appliances.

Remove loose or flaky material from the wall surface as well as any projections that may rupture the Wallrock Dampstop Thermic, fill any holes with a suitable filler. The surface may need priming if excessively porous or absorbent: we recommend diluting Wallrock Dampstop Adhesive 1:1 with water to form a primer, allow to dry thoroughly.
Brush the adhesive onto the wall over a slightly wider area than the Wallrock Dampstop Thermic strip - you will need typically 160-250ml per square metre depending on the condition of the wall. The adhesive must be applied evenly.
Apply Wallrock Dampstop Thermic directly to the pasted surface - black side to the wall.
NB. Using a wallpaper hanging brush carefully remove any air bubbles, brushing from the centre outwards, ensuring there are no wrinkles or air pockets remaining as they will not dissipate during the drying process.
When applying multiple lengths we recommend butted joints are used as follows:
Ensure Wallrock Dampstop Thermic Adhesive is applied liberally and evenly at the butt joint to reduce the possibility of damp tracking through seams. This technique is adequate to combat small localised damp problems.
In the event the maximum possible damp resistance is required we recommend 2 layers of Wallrock Dampstop Thermic are applied being careful to ensure the seams are offset with the layer beneath.
Alternatively extra resistance can be achieved by applying a single layer but overlapping at the seams by minimum 20mm. It is important to note that with this technique the contours of the overlap are likely to remain noticeable even after painting or overhanging with wallpaper.
Once complete allow to dry thoroughly - 48 hours may be sufficient but much longer may be required as the foil surface will slow down the drying process.
Once thoroughly dry, we recommend the treated area is thoroughly checked to ensure that Wallrock Dampstop Thermic is fully bonded. The Wallrock Dampstop Thermic foil surface can simply be painted (the surface may need priming, please ask the paint manufacturer), overhung with lining paper, insulating wallpaper or a decorative wallpaper.
