Description

Rust-Oleum Mathys Dacfill Waterproofing

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.


Features & Benefits

  • 100% watertight system
  • Resistant to UV radiation, acid rain, heat, frost and pollution
  • Barely flammable and self-extinguishing
  • Vapour-permeable
  • Water-based formulation contains no dangerous solvents
  • Single pack product
  • Excellent resistance to extreme temperature
  • Easy to apply with a brush, roller or airless spray
  • 10 Years product guarantee*

* All guarantees are subject to approval by our Technical Department prior to purchase and/or use.

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: 

Is this product suitable for asbestos tiled roof. thanks

Answer from Rawlins’ Technical Team: 

Yes it is, you will need to clean the roof inline with local legislation and apply two coats of Rust-Oleum Mathys Primer 44 HS before application.

questions Geoff Lee on 2019-08-31 11:56:12
Question: 

would Dacfill seal asbestos sheets where they over lap on the joints

Answer from Rawlins’ Technical Team: 

Asbestos should be primed with Rust-Oleum Mathys Primer 44 HS, fill up joints with Rust-Oleum Mathys Elastofill, bridge active cracks with Rust-Oleum Mathys Dacfill Fleece in conjunction with Rust-Oleum Mathys Dacfill Waterproofing.

questions Noel on 2019-07-28 17:59:39
Question: 

Would this work on external brickwork to waterproof a wall and small cracks in the mortar etc. to stop water ingress?

Answer from Rawlins’ Technical Team: 

No, but the Rust-Oleum Mathys Murfill Waterproofing Coating system would.

questions gordon on 2018-01-26 14:09:21
Question: 

Rust-Oleum Mathys Dacfill Waterproofing Hello is this product effective if applied to the inside face of the roof. i.e. from inside the garage to the ceiling side rather than climbing up onto an asbestos roof? Thank you

Answer from Rawlins’ Technical Team: 

No, to provide waterproofing protection it must be applied to the top side of the roof.

questions John Harrison on 2015-09-11 23:34:46
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?)
Answer from Rawlins’ Technical Team: 

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.
