Rust-Oleum Mathys Fillcoat - Elastic Waterproofing Solution for Roofs

Fillcoat Waterproofing is a high-performance elastic paint designed to instantly waterproof roofs, non-walkable terraces, gutters, ridge-pieces, chimney stacks, and pipes. This versatile product offers excellent adhesion to a wide range of substrates including bituminous substrates, hard PVC, polyester, zinc, aluminium, glass, and tiles. With its improved UV resistance and hydrophobic properties, Fillcoat ensures long-lasting protection and durability.



Application & Usage

Fillcoat Waterproofing can be applied using a brush, roller, or airless spray. It is suitable for use in all weather conditions, making it a reliable choice for immediate leak repairs and preventive maintenance. For porous materials such as concrete, stone, or wood, pre-treat with Mathys Primer 44HS to ensure optimal adhesion.



Preparation & Application Conditions

  • Ensure surfaces are clean, dry, and free from dust, mud, grease, moss, and withered leaves.
  • Fillcoat can be applied directly on suitable substrates or reinforced with Dacfill Fleece for active cracks or repeatedly repaired spots.
  • Avoid applying on polystyrene insulation or new concrete less than 2 years old.
  • Do not use as a priming coat under Dac Hydro Alu.



Why You Should Buy

Fillcoat Waterproofing stands out due to its thick elastic coating that stops leaks instantly. Its excellent adhesion and ability to be applied in various weather conditions make it an indispensable solution for maintaining and protecting roofs and other structures. With a 5-year shelf life, this product offers both reliability and longevity.



Recommendations & Restrictions

  • Recommended for use on roofs, non-walkable terraces, gutters, ridge-pieces, chimney stacks, and pipes.
  • Not suitable for polystyrene insulation or new concrete.
  • Ensure all surfaces are properly prepared and pre-treated if necessary.

questions mick Coulson on 2018-11-27 19:03:17
Question: 

Would this product work to seal and stop a leaking galvanized gutter on a commercial property?

Answer from Rawlins’ Technical Team:

Rust-Oleum Mathys Fillcoat can be applied directly to clean, weathered galvanised gutters. So depending on the actual cause of the leak in the first instance and how wide any gap at overlap edges is and how much movement may be expected, the answer would be yes. However there are alternative and complimentary products that may be required such as Rust-Oleum Mathys Fillcoat Fibres, Rust-Oleum Mathys Dacfill Fleece, etc. Contact our Technical Team on 0113 2455450 or [email protected] if you are unsure or would like more information/help with your project.

questions Robert on 2018-05-17 11:13:35
Question: 

I have a garage with a corrugated asbestos roof. It's old and has a few hairline cracks that allow water in during bad weather. Would Rust-Oleum Mathys Fillcoat be suitable for making this roof more waterproof, or would you recommend something else?

Answer from Rawlins’ Technical Team:

Rust-Oleum Mathys Fillcoat would be OK for this, after cleaning, porous materials (such as asbestos) must first be dried and pre-treated with a coat of Rust-Oleum Mathys Primer 44 HS. In case of repeatedly repaired spots, important or active cracks, Rust-Oleum Mathys Fillcoat is to be reinforced with Rust-Oleum Mathys Dacfill Fleece: apply a coat of Rust-Oleum Mathys Fillcoat (at a rate of 1 litre per m²), unroll Rust-Oleum Mathys Dacfill Fleece in it and cover it immediately with another coat of Rust-Oleum Mathys Fillcoat.

questions Peter Evetts on 2018-02-03 22:06:59
Question: 

We own a camper van. The model has a history of leaks from the corrugated metal roof.There are roof bars mounted in the rain channel and is prone to leaking. There are also 3 roof lights that have been sealed with silicone and these can also cause leaks. To mitigate any leaks I want to paint the roof in an attempt to head off any problems.Would this paint be suitable for this purpose? The roof is in a silver finish.Is this paint available in this colour?

Answer from Rawlins’ Technical Team:

Rust-Oleum Mathys Fillcoat would be a good option for this duty. However, it is a paint and therefore can’t repair the structural fault that is already present even after attempts to repair with sealants. As silicon is advised as being present, the Fillcoat, like all paints, will not adhere to that.

questions tom leslie on 2017-04-15 12:08:57

Answer from Rawlins’ Technical Team:

Rust-Oleum Mathys Fillcoat would be suitable for this application and for 28m² you would require a minimum of 30 litres. The product does dry hard but remains flexible not tacky.
