Description

We no longer stock this product, but can recommend Rust-Oleum Mathys Dac Hydro Plus as a great alternative.

Rust-Oleum Mathys Dac Hydro D is a high build, waterborne acrylic pitched roof coating that renovates and protects in a durable way concrete and terracotta roof tiles. It provides excellent resistance against weathering and a particularly aesthetic and durable decorative finish which breathes, is flexible and adheres to most mineral substrates.

Features & Benefits

  • Higher layer thickness gives extra protection
  • Resistant to UV radiation, acid rain, heat, frost and pollution
  • Rain-proof after just 1 hour
  • Smooth decorative finish with lasting colour and gloss
  • Safe and easy to use

Surface Preparation

After a good cleaning with pure water under high pressure (200 bars), all substrates have to be dry, clean, not chalking and normally absorbent (untreated roof tiles). For very closed substrates like varnished or enamelled tiles, an adhesion coat of Rust-Oleum Mathys Noxyde diluted with 25% water should be applied. For all other substrates: corrugated asbestos cement sheets, concrete tiles of the Redland type and all weathered and/or very absorbent substrates, it is necessary to apply an adhesion coat of Rust-Oleum Mathys Primer 44 HS. It is recommended to perform an adhesion test prior to use and it is not advisable to apply Rust-Oleum Mathys Dac Hydro D on artificial slates type “Eternit”.

Directions for Use

To ensure homogeneity, coating materials should be thoroughly stirred prior to use.

Application & Thinning

  • Brush: Apply undiluted
  • Roller: Apply undiluted
  • Air-atomised spray: Not recommended
  • Airless spray: Dilute with max. 3% of water. Nozzle: 015 - 021 / Pressure: 160 - 220 bars
  • Cleanup: Water

Application Conditions

Temperature of air, substrate and coating material must be above 8°C and relative humidity below 80%. The substrate temperature must be at least 3°C above dew point.

Remarks

Apply in 2 coats to avoid local gloss differences.

Question: 

Hi, I have a slate roof. Can this paint be used?? Many thanks Gareth

Answer: 

Rust-Oleum Mathys Dac Hydro D is suitable for concrete and terracotta roof tiles. For slate tiles we would recommend Rust-Oleum Mathys Dac Hydro Plus once the surface has been primed with either Rust-Oleum Mathys Primer 44 HS or Mathys Pegafix.
