Product Description

Rust-Oleum Mathys Durbocem is a problem solving coating for damp walls. The paint is specially formulated to adhere and build a strong bond with the damp surface it is applied to, because it contains cement the moisture on the substrate actually helps the paint cure and become stronger coating.

Rust-Oleum Mathys Durbocem is a solvent-based paint based on plasticized acrylic resins for inside and outside use, by choosing a product like Durbocem you eliminate the usual issues encountered with normal paints in a damp environment. Rust-Oleum Mathys Durbocem allows the surface to breathe so water pressure does not build up behind the coating which in turn prevents any flaking paint or diversion of damp to other areas.


• Builds a strong bond with the damp substrate.
• Can be applied on chalking substrates.
• Builds a strong bond with cement-based substrates.
•• Contains cement, and therefore this product is extremely suitable to be applied on damp substrates.
• Can be recoated with Paracem (when the substrate is dry).

I have old exterior walls from 1915, a mixture of clay tile block, masonry, plaster and cement. It also breathes damp, I think the clay tile block retains moisture more than typical exterior wall structures? What would stick the best as all other paints seem to peel off after time due to the moisture.


Rust-Oleum Mathys Durbocem is ideally suited to be applied to damp walls, however we would advise defining exactly why the walls are so wet. That way we can be sure to provide the most appropriate solution.

Question: My kitchen is in the basement of a 19th century cottage. One wall is built with clunch , a very porous stone, the outside of this wall is under soil. There is a continuous patch of damp and mould where the moisture seeps through the stone. I use an anti mould spray and paint it with breathable clay paint but the stain always re-appears . Will this product help the problem and can I use clay paint over it.

A water stain will keep reappearing through a clay paint. The surface needs to be sealed to prevent the moisture coming through, a clay paint is not going do this.

Zinsser Watertite would be our suggestion from our range, you would need to remove the existing paint coatings and any plaster back to the bare clunch stone. Treat mould etc, then apply the 2 coats of Zinsser Watertite.

This can be mixed to a pastel colour to avoid applying a top coat or you can paint over the Watertite using a clay paint provided it has had 14 days to fully cure. You will lose the anti mould properties if you decide to paint over the Watertite however.

Question: Hello,
I have a rising damp issue on one of my walls which has a layer of paint and plaster. Is this product suitable and can I paint the wall after with interior paint? I was originally looking at the watertite product but seem to only be able to use it on brick walls?

Coo-Var Anti-Damp Paint should be better suited to your project.

Question: Hi, I'm looking for a product for an exterior retaining wall. I have bleached and pressure washed it and in some areas the paint has come off revealing patches of masonry. Is this a suitable product and should I put a primer/undercoat on the bare areas first?

Rust-Oleum Mathys Durbocem should be ideal for this sort of application and does not require any primers or similar applying before application.
