PREPARATION OF NEW SURFACE
All surfaces must be free from dirt, dust, oil and grease. The plaster should be left to dry for at least four weeks depending on weather conditions before painting. Remove all nibs and other excrescences by using emery stone, glasspaper (sandpaper), etc. make good any surface defects with proper putty. If efflorescence is present, remove it with scrubbing brush. Do not use wire bush.
PREPARATION OF PREVIOUSLY PAINTED SURFACES
On previously painted surfaces scrape to remove all old pain, which is loose and flaking thoroughly brush out from the pores of old distempers, cement paints, etc. apply one normal coat of Rainbow Perfecton Wall Primer Sealer or Rainbow Water Based Wall Primer. Make good the defects of the walls by using Rainbow Wall Putty.
PREPARATION OF PUTTY
It has been generally established that major cause of complaint about flaking paints on the interiors is due to poorly prepared putty. As such we strongly recommend that the Rainbow Wall Putty suggested should be used.
Apply a thinner coat even if the surface is in good condition. For thinning use 1 liter of turpentine to 4 liters of Perfecton. Allow it to dry overnight.
If you want to paint using Rainbow Plastic Emulsion, 2 to 3 coats of Rainbow Plastic Emulsion should be applied with brush, roller or spray. Add 2 to 2½ liters of water to 1 gallon of paint before use. For final coat, some extra water may be added to improve flow. Clean all equipment and brushes with water soon after use.
Coverage will be depending on surface and application but on an average, one liter of Rainbow Plastic Emulsion will cover 12 to 16m2 per liter per coat on a normal smooth surface. If the surface is rough or absorbent, coverage will be less.
