In addition, our company offers several solutions if your house suffers from damp and mould, and if it has a scruffy external appearance, then we would suggest our exterior wall coating system which is guaranteed for 20 years.

Promain offer a range of clear sealants, suitable for waterproofing a range of indoor and outdoor surfaces, including both horizontal and vertical surfaces. Whether you have an outdoor wall you want to protect from wind and rain or a patio that you want to waterproof, you'll find the clear sealant you need right here. Once the above is done, lightly brush the wall with a soft broom head or old emulsion brush to get rid of dust. Once the wall has been cleaned and given sufficient time to dry, you are ready to start the sealing process. When selecting a sealer for your wall, you want to choose a 100-percent acrylic sealer. I always recommend selecting one that has a volume of solids no less than 15 percent, such as Defy’s Acrylic Waterproofing Sealer (www.defyinfo.com). With lower-solids sealers (those with a solids level in the 10-percent range), you can have difficulty getting an attractive, even sheen and it may take additional coats of material to get the look you want. After waiting about a day for the surface to dry, fill up the pump sprayer with your sealer of choice and spray it onto the material. Be sure to spread any runs or drips while they are wet with a paint roller. Allow the sealer to dry however long the instructions say before adding a second coat. Stormdry only requires one coat, and we found that it was touch-dry after a few hours and water repellent after two days and largely water resistant after 28 days.When using acrylic sealers, the sealer can darken the surface slightly as well as add some level of sheen or gloss, so it’s always best to first apply a little material in an obscure location to make sure it’s the look you’re after before you seal the entire surface. Acrylic sealers are the perfect solution for use on walls, but avoid using them on floors as they simply may not hold up to the rigorous wear and tear of daily foot traffic. One specification to look out for is the VOC level. VOC stands for volatile organic compounds, and they are incredibly bad for your health and are regulated by law. Look for lower VOC levels because they will be less toxic and have lower fumes. Freezing and Thawing: Freezing and thawing can cause property damage to floors and walls, especially in locations prone to heavy winters. A sealer will prevent water from getting into your surfaces.

I will post this on our blog, with my reply, and your details removed, to see if anyone else has any suggestions. Dependent on the porosity of the surface 1 litre of product should cover approximately 4 to 6 m2 . STORAGE / SHELF LIFE

PREPARATION & APPLICATION

That is a question we get asked often and generally it is more expensive than internal but does so much more and is not marketed as decorative but PROTECTIVE because remember, your walls outside get a hammering from the weather.
