I have a sandtex painted brick end of terrace cottage in Lymington. I want to cover the exterior surfaces ( approx 115 sq. m.) with a colored water prof breathable coating via paint brush. Are your products suitable for my application. What approach would you recommend? I can send you photos if needed. Thanks David


Rust-Oleum Mathys Murfill Renovation Paint would be an excellent choice, for old paints in good condition, simply clean and dry and apply 2 coats of Rust-Oleum Mathys Murfill Renovation Paint. Based on 115m² you would require 46kg to apply the required 2 coats.

questions Y Sim on 24/01/2018

We have an 8 foot retaining wall in our yard ,recently rough casted ,but we hate it !!.Would we have to have the wall re-rendered before paining, or could the rough cast be coated ? Also ,because the wall is retaining, it always looks & probably is a bit damp.Any advice would be welcome Thank you


We would instead recommend Rust-Oleum Mathys Durbocem for this application as it 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. It also 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.

Question: Can this be used directly onto brick? thanks

No. Assuming the brick surface to be painted is 'open and porous' (not smooth like engineering brick) it would first need to be primed with Rust-Oleum Mathys Primer 44 HSMathys Fixonal or Mathys Pegafix before applying 2 coats of Murfill Renovation Paint in your chosen colour.

questions Ian Huws on 04/03/2016
Question: Can your product be used over K501 treated walls?

Sika Liquid Plastics K501 is based on waterbased silane-siloxane technology so Rust-Oleum Mathys Murfill Renovation Paint SHOULD be ok to apply over this type of waterproofer but we would always recommend a sample patch is carried out to ensure compatibility and adhesion. To test, paint about 1m² of Rust-Oleum Mathys Murfill Renovation Paint out onto the surface in an inconspicuous area, allow to fully dry for 3-5 days and then check for any signs of potential issues and test adhesion.

questions zana mathews on 29/02/2016

Can you advise me of its weatherproofing qualities?


Rust-Oleum Mathys Murfill Renovation Paint will waterproof the wall but still allow the surface to breathe. It remains permanently elastic and extremely resistant to ageing, contamination and dirt pick up. It is resistant to UV, acid rain, heat, frost and pollution. Any cracks over 0.5mm wide should be filled with Rust-Oleum Mathys Elastofill and any active cracks should be bridged with Rust-Oleum Mathys Murfill Reinforcement Fleece.
