EFFLORESCENCE REMEDY
EFFLORESCENCE REMEDY
Description
White fluffy powder deposits on plaster (usually new plaster), bricks and cement finishes, which can affect painted surfaces.
Cause
• Alkaline salts, which are water-soluble, crystallize as white fluffy deposits when the water in a surface dries out.
Remedy
Dust off the deposits or rub off with a dry rag, then wipe with a very slightly moist (not wet) cloth.
Note: Removal of the white deposits should not be done wet, as this will cause the salts to go back into solution and later crystallize again as they dry out.
Following dry removal, keep checking the affected area over a period of time, and continue dry removal of any further salts. When they no longer appear, prime the area with an alkali-resisting primer before further decoration.
DECORATOR’S DODGE
After dry-wiping off the white salty deposits, lightly sand the affected area; this will 'open up' the plaster surface, which allows any further accumulations of salt to dry out.
