Plastic paint on a traditional building will trap in moisture if defects are present, don’t get me wrong I have seen many buildings with plastic paint with no problems. The buildings that have had small external defects in the paint seem to exacerbate the problem as the moisture becomes trapped. I often find these are South facing elevations that have a small amount of thermal movement through the seasons, once this has occurred over a period of time it is a very slow process to dry the wall back down…….. Many people call in a decorator that has a one fix solution, they scrape back the blown paint, skim over with some filler and paint back over it with some more plastic paint. This is a short term fix, as the wall is still wet the paint doesn’t key or will lose its key and you will have exactly the same problem next year, it’s a vicious circle.
We offer paint removal from stone and bricks, we use a patented system that we have had great results with. We use mainly 2 systems, 1 is a super heated Thermtech hot water system that can be heated up to 150 c and we also use another system that produces a swirling soft abrasive, different products can be added depending on the application and the building material. We actually our own machines and can offer test patches to ensure we give the best advice and the correct price for the works. Our training has been carried out in collaboration with Restorative Techniques who actually make and supply the machines.
This is a before picture, this property had been painted many times and was suffering from penetrating dampness.
All the plastic paint removed, hard cement pointing removed, and we re-pointed using a lime mortar like when it was originally constructed
As you can see in the picture below this building now looks absolutely stunning. Why would anybody actually even want to paint this!
Please see the below videos of our systems in action.
The below system is slightly more abrasive than just the hot water, this is used when there is sometimes a softer cementitious base coat that needs to come off.
