Rust-Oleum Mathys Dacfill Waterproofing is a watertight, water-based liquid membrane for pitched roofs. It forms a lasting elastic coat without joints or seams on sloping roofs (min. 5% slope). Rust-Oleum Mathys Dacfill Waterproofing has been tested and independently approved for asbestos encapsulation which makes it an excellent alternative to asbestos sheet replacement saving cost, time and expensive disruption.

Rust-Oleum Mathys Dacfill Waterproofing is based on water dispersed acrylic resins and the substrate must be well cleaned and dry, free from flakes, gravel, dust and dirt. Fill up joints with Rust-Oleum Mathys Elastofill, bridge active cracks with Rust-Oleum Mathys Bridging Fleece (15cm x 50m Roll). Additionally it can be reinforced mechanically with Rust-Oleum Mathys Dacfill Fleece.

Coverage
1. Consumption per coat: 0,6 - 1,5 kg/m² (dependent of the substrate).
2. Steep roofs (without fleece): 1,3 - 2,5 kg/m².
3. Roofs with a little slope (with fleece): 2,5 - 3 kg/m² (water stagnation).

Surface Preparation
The substrate must be well clean and dry, free from flakes, gravel, dust and dirt. Fill up joints with Rust-Oleum Mathys Elastofill, bridge active cracks with Rust-Oleum Mathys Bridging Fleece and apply one of the following priming coats:

Roofing or bituminous materials over 1 year old can be coated directly with Rust-Oleum Mathys Dacfill Waterproofing. Zinc, galvanised steel, copper, lead and aluminium can be recoated with Rust-Oleum Mathys Dacfill Waterproofing, if required, after degreasing and slight sanding.

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

Application & Thinning

  • Brush: Use a square brush. If necessary dilute with water.
  • Roller: Use a roller with long hairs (long nap). If necessary dilute with water.
  • Air-atomised spray: Not recommended.
  • Airless spray: Nozzle: 18 - 23 / Pressure: 220 bars
  • Cleanup: Water

Application Conditions

  • Drying weather: enough air ventilation (light breeze) or sunny conditions.
  • Min. Temperature: 5°C.
  • Max. Relative humidity: 80%.

Remarks

  • The use of the Rust-Oleum Mathys Dacfill Fleece is necessary for every roof with a slope < 5%, in case of water stagnation and when movements of the substrates can be expected or can be feared (for more information about the application of the Rust-Oleum Mathys Dacfill Fleece, please consult our Technical Department).
  • For applications where permanent stagnating water is to be feared or when the Rust-Oleum Mathys Dacfill Waterproofing coat has to be protected against pollution (e.g. Rust-Oleum Mathys Dacfill Waterproofing White), it is recommended to protect the Rust-Oleum Mathys Dacfill Waterproofing with a coat of Rust-Oleum Mathys Coating PRT (@ 100 g/m²). This system is not designed for immersion purpose; in case of application in gutters, a minimum slope for rainwater evacuation must be respected.
  • Do not apply on tar, soft PVC or bituminous materials < 1 year.

Question

I am building a 4m x 3m summer house which will be attached on one side to a 2.1m x 5m shed. My intention is to roof the summer house with bitumous underfelt then lay a good quality top felt (to match the shed roof). The shed roof is ok, but beginning to show its age (8 yrs). Can the Dacfill be painted over the old felt to give it a new lease of life? And could it be painted over the new underfelt (instead of using a top felt) to match the shed? (or even straight on the new plywood roof?)

John Harrison from London (UK) - 11/09/15

Answer

Rust-Oleum Mathys Dacfill Waterproofing wouldn't be the product to use but Rust-Oleum Mathys Dacfill HZ would. Without major complications you're only going to be able to paint the existing shed roof for now. Then when the new summer house roof has aged for more than 12 months you can paint that as well to match.
