To prepare the mortar, pour 7.50 liters of water into a clean container and add slowly the content of BETOFINISH F (25kg). Mix using spiral paddle in slow speed heavy duty drill for few minutes till a homogeneous lump free consistency mix is achieved. Always add powder to water and not the other way around.
Apply BETOFINISH F manually with spatula or steel trowel with a maximum thickness of 3 mm per coat. The product can be applied in more than one layer. Leave the surface rough if the application of following layers is needed.
Only the last coat can be smoothed with sponge trowel few minutes after the application. If surface dries too fast during the smoothing, it can be dampened by water spraying to facilitate the trowel application. Care should be taken not to overwork the surface.
When high mechanical resistant thin plaster is required, BETOFINISH C must then be reinforced with a special fibers tissue.
Curing is not generally needed however under extreme conditions - high temperature and drying winds, BETOCURE AR shall be used as a curing compound.
BETOFINISH F should be removed from tools and equipment and mixers with clean water immediately after use. Cured material should be removed mechanically.
The support must be perfectly cleaned, free from dust, inconsistent parts, traces of form stripping oils, efflorescence, rust etc.
Saturate the surface with water to eliminate possible water absorption at the moment of application.
BETOFINISH F can be harmful to skin as it contains cement powders which may releases alkalis when mixed with water.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
