Product sheet

DAKSHAMPOO® Roof Coating Bonding Primer is a solvent-free, colourless 1-component adhesive based on epoxy resin, especially for subsequent finishing with DAKSHAMPOO® roof paints.

Intended use:

The roof coating bonding primer is a water-dilutable 1K binder for naturally baked and engobed roof tiles and other critical substrates in the roof area. Also suitable for non-absorbent mineral roof tiles.
lic surfaces inside and outside. Do not use on roof surfaces with standing water.

Features:

A roof coating bonding primer with excellent bonding properties. Fast drying. Dilutable with water, environmentally friendly and low odour. Universally paintable with DAKSHAMPOO® emulsion paints.

Binder:

Epoxy resin dispersion

Specific gravity:

approx. 1,05 g/cm3

Color:

kleurloos

Package Contents:

750ml, 5 kg and 15 kg

Surface preparation:

The existing roof surfaces must be prepared in such a way that they are firm and stable, clean, dry and free from vegetation, weather influences, grease, silicone and oxide layers.

The roof surfaces are cleaned of algae, lichens, moss and other dirt with a high-pressure cleaner; for greasy dirt (soot) with overheated steam. The cleaning should be carried out in the direction of the drain with a spray distance of approx. 10 cm and a pressure of at least 160 bar. Or use the DAKSHAMPOO® quick cleaner with a high-pressure cleaner with a maximum of 130 bar water pressure.

Processing:

DAKSHAMPOO® Roof Coating Bonding Primer is ready to use, but can be diluted slightly with water to achieve the optimum processing viscosity.

Brush and roller application:

Apply undiluted.

Airless spray application:

To set the optimum spray viscosity, DAKSHAMPOO® Roof Coating Bonding Primer can be diluted with water up to a maximum of 10%. Airless spray pressure approx. 150 bar, nozzle bore approx. 0.021″, spray angle 30 – 50°, distance approx. 40 – 50 cm. Piston pumps such as GRACO UltraMax devices with a hose length of up to 40 m can be used. Due to the large number of different substrates and substrate properties, we recommend carrying out a test coat to check the adhesion before coating.

Processing conditions:

Do not process at air and object temperatures below +8°C. Do not apply airless in strong winds. At high object temperatures (above 40°C) the DAKSHAMPOO Roof Coating bonding primer is applied diluted with approx. 10% water; if necessary, moisten the surface beforehand. Do not apply in rain or expected rain.

Consumption:

Laboratory values: Approx. 100 – 125 g/m² or 8 – 10 m²/kg per coat on a smooth substrate. The consumption figures for the roof coating bonding primer are guide values ​​that can increase due to surface roughness and structure and profile waves. Due to the different structural substrates, the exact consumption quantities must be determined when painting or rolling and when spraying on the object.

Practical values:

Experience has shown that for an average profiled and structured roof surface, depending on the application method, a total material consumption of approx. 150 – 200 g/m2 roof coating bonding primer can be estimated.

Drying times:

At +20° C and 65% humidity it can be painted over after approx. 4 hours. Lower temperatures and higher humidity extend these times. DAKSHAMPOO® roof coating bonding primer must not be exposed to weather influences for a long time; the revision with DAKSHAMPOO® roof coatings must therefore be carried out quickly.

Cleaning the devices:

Clean brushes and rollers with water immediately after use. Clean airless devices thoroughly with water.

Storage:

Store in a cool, but frost-free place. Unopened packages have a shelf life of approx. 1 year. Opened containers should be processed as soon as possible.

EU limit value for the product: (Cat. A/g): 50 g/l (2007) [30 g/l (2010)] This product contains a maximum of 29 g/l VOC
