As opposed to conventional liquid products, Dryseal can be applied in one working operation to achieve the desired loading for maximum effectiveness. Timber should always be cleaned with a surface biocide prior to application to avoid staining by microscopic organisms.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. The cream will penetrate and absorb into the substrate within 30 minutes to several hours, depending on surface porosity.Checked to see how effective it is during a wet day and you can see the water beading up and rolling away unlike untreated brickwork. Just been out to check the render, and right where the damp is coming through the wall, I noticed a hairline crack as shown in the pic below. The Dryseal system is also suitable for insulated “warm” roofs and can be finished to look like lead or zinc by adding decorative trims. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. The stuff is meant to be completely waterproof (sheds water and dirt by beading) soaks into porous stone and mortar up to 17mm depth and dries to a breathable, clear coating lasting minimum 10 years.

Q: Hi, I covered my gable end with 2 coats of Thompson's water sealer about 2 years ago and I still have water coming in. All you need to do is provide a few details by completing the short form below and we’ll pass your enquiry directly to our exhibiting partners, who will be in contact within 7-10 working days. It certainly is quite expensive however we all know that not dealing with damp correctly could cost well in excess of the cost of this. Ideal for walls with cavity fill insulation, to prevent saturatuion through rain penetration, Ideal for walls with cavity fill that has already become saturated, as DrySeal allows the masonry to breath encouraging it to dry out and preventing any further water ingress.

Dependent on porosity, the effective siloxane ingredient deeply penetrates the substrate within a short period of time (between 30 minutes to several hours) where it reacts to become a polymer silicone resin. we did use 'waterseal' about 10 years ago, but I would guess that needs redoing now - also this new stuff is supposed to be breathable which would be good. I applied the cream by hand using a small 30mm paint brush, quite a task but seems to have worked well . This highly effective damp proofing system will also provide a highly effective additional barrier to flooding as part of any existing flood protection system.
