cement, cement roof tiles, galvanized iron roofs.
Make sure that all surfaces are clean and free
of any loose particles.
Never !! paint over surfaces on which the paint
is failing, the area in between which seem to be sound is already
weak and will soon fail.
The new paint will tend to pull the old system off
if not prepared properly.
1.1 Cement and clay roof tiles:
High-pressure wash the entire roof.
Check the condition of the roof as follows: When the surface
is dry, press a length of masking tape securely onto the roof surface,
then pull it off quick. Examine the adhesive side of the tape. If no
coating is removed, and no dirt or chalky material is apparent, then
the surface is ready for the first coat of paint.
If, with the tape test method, the paint coating is removed,
you need to strip the existing paint film.
1.2 Galvanized Iron Roofs:
The surface must be sound. If the paint system is frail
or flaking, completely remove all the old paint, then high-pressure
Unpainted galvanized iron: remove any rust, clean with
galvanized iron cleaner and then rinse thoroughly.
Film thickness is the actual amount of paint on the surface.
The most common problem is that only one coat is applied. The most serious
problem occurs when water is added to the paint and only 1 coat is applied.
Two coats must be applied.
Allow at least 4 hours drying time between coats.
Apply with brush, roller or airless spray.
