All bricks and mortar contain salts. When your masonry walls absorb moisture or become wet, these salts will surface on the face of your masonry wall (this is known as efflorescence).
This is very common on the lower courses of homes through rising damp, as well as fences and retaining walls that are exposed to the weather.
If these salts are allowed to surface and naturally weather away, they can be practically harmless to your masonry wall or render.
On the other hand, if you apply a coat of paint or acrylic products to your masonry walls or render, you are, in effect, trapping these salts between the face of your masonry wall or render. This is when these salts become harmful.
The salts become acidic and very quickly break down not only the paint, but also your masonry or rendered walls, causing blistering and failure of both surfaces. Most bagging/rendering companies use synthetic & acrylic renders and paints. They also contain chemicals, like hydrogen, cyanide and acetylene, which makes them non-breathable.
This is what you can expect from typical bagging and rendering companies. Their products are not as advanced as ours and therefore require either re-painting or maintenance after only a couple of years.
Renfec have developed a style of high quality, textured render with consistent colour throughout. Our product is made of high strength pigments which are made to endure! Renfec’s product is pure, high-tint strength and long-lasting. We are able to provide our customers with a variety of colours to suite every project.
