Spot detachment or deterioration of plaster Salts contained in the wall plaster mass (or in bricks, brick mortar, and concrete) dissolve from the moisture also contained in it, rise to the surface, crystallize, and manifest by forming a whitish powder.

When dealing with plaster damage and small repairs there are two high quality cementitious sealants for spot repairs are available: SUPER FLEX POWDER (p. 269) for damage and cracks of up to 15mm and D-66 REPAIR (p. 238) for cracks and holes up to 30mm. ii.
