Suitable Substrates

Weathered (min. 10 years aged), absorbent concrete roof tiles and engobed or glazed clay bricks.

Please Note: Modern roof tiles sometimes offer refined surfaces, e.g. dirt-repellent, self-cleaning surfaces. Previously applied trial coatings (test areas on site) on such surfaces are essential for check of proper adhesion.

Substrate Preparation

First of all replace or repair damaged roofing and sealing materials as well as defective joints and connections by an appropriate roofing specialist.
Provide for adequate ventilation (air circulation/exchange behind the roofing material). Carefully remove all organic substances, such as moss and algae, as well as loose/brittle substances and dirt by high-pressure water jet. Always work directed towards the draining pipe to avoid excessive penetration of moisture beneath the roofing material.
Cleaned substrates must be solid, sound/stable/load-bearing and free from all substances that may prevent good adhesion.

Preparation of Material

Stir well before use. The priming coat can be diluted to a max. of 5 % with tap (potable) water.

Method of Application

Disboroof 408 Dachfarbe is applied by suitable spraying equipment with extension / spray lance
(Airless, max. 150 bar, nozzle size: 0.021 to 0.025 in.).

Surface Coating System

Concrete Roof Tiles:
Moisten the weathered, absorbent concrete roof tiles (aged for min. 10 years) or apply two coats of Disboroof 408 Dachfarbe directly after having finished the cleaning procedure.

Clay Bricks (engobed & glazed):
Prime the well prepared, dry substrate with Disbon 481 EP-Uniprimer. Apply 2 coats with Disboroof 408 Dachfarbe after a waiting time of at least 3 hours (at 20 °C), but within max. 3 days. Allow a waiting time of min. 2 hours between the first and the second coat.

Note: Apply a trial coating on new concrete roof tiles (aged < 10 years) with Disboroof 408 Dachfarbe or Disbon 481 EP-Uniprimer + Disboroof 408 Dachfarbe, allow to dry and check for sufficient adhesion.

Consumption

Approx. 330 - 380 ml/m² or 360 - 420 g/m² per coat, depending on the type and surface condition of the roofing material. Determine the exact amount of material required by coating a test area on site.

Application Conditions

Material, Ambient Air and Substrate Temperature:
Min. 10 °C, max. 35 °C during application and drying.

Drying/Drying Time

At 20 °C and 60 % relative humidity, dust-dry after 4 hours and completely dry after approx. 24 hours.
