plaster primer


Primer for plaster

B-74S PLASTER PRIMER prevents plaster from dangerous
“desiccating or burning up” in the case of highly absorptive surfaces.
B-74S PLASTER PRIMER is a non film-forming substance, and so doesn’t
form a separative layer between plaster and masonry. B-74S PLASTER PRIMER
makes the treated substrate water-repellent to a certain extent without
completely sealing it. Moisture-vapour transmission is retained.



• suitable for highly absorptive substrates
