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.

My cellar walls are bare brick, damp and subject to mould/fungus. Can this be painted directly onto the bricks and mortar? Thank you.
Answer from Rawlins’ Technical Team:
While this can be applied to a bare substrate such as bare brick it should be noted that this paint requires excellent ventilation during application and curing as it has very strong odour.
As an alternative assuming the walls are clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Zinsser Watertite.

Question:
Good morning. Your Rust - Oleum paint looks ideal for my basement kitchen walls which are very prone to damp. I have spent the last couple of months using a dehumidifier , and this has helped dry things out ready for a breathable paint. Can the Rust-Oleum be tinted, please, or does it have to be white? Thank you.
Answer from Rawlins’ Technical Team:
Rust-Oleum Mathys Durbocem is a sovlent based paint that after application will require excellent ventilation for approximately 2 weeks, in this time it will give off odours.
This paint cannot be tinted but it can be over painted with Mathys Paracem which can be mixed to many RAL and BS colours.
Alternatively assuming the substrate is clean, dry prior to application and can be kept dry for approximately 72 hours after application to allow the product to cure we can recommend Keim Optil.
This is available in a range Keim specific colours and would be a lower odour option.

Answer from Rawlins’ Technical Team:
Rust-Oleum Mathys Durbocem wouldn't be suitable for this application, we would instead recommend Coo-Var Anti-Damp Paint.

Question:
I am property convenor for a Church and the window ingoes are plastered on the sandstone. Would this paint be suitable to stop moulding peeling of paint?
Answer from Rawlins’ Technical Team:
For the interior decoration of walls and ceilings in traditional and historic buildings, including churches, we would recommend Zinsser Grade 1 which acts as a primer, sealer and finish coat in 1.

Question:
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.
Answer from Rawlins’ Technical Team:
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.
Answer from Rawlins’ Technical Team:
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?
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?
Answer from Rawlins’ Technical Team:
Rust-Oleum Mathys Durbocem should be ideal for this sort of application and does not require any primers or similar applying before application.
