SILRES® BS 310 may be added undiluted to aqueous masonry coatings and primers either during or after manufacture. We recommend adding 1 - 3 wt% to masonry coatings.

SILRES® BS 310 is used in undiluted form as an additive for aqueous indoor paints or coatings in order to improve the workability. SILRES® BS 310 is very compatible to indoor paints and positively influences the wetting and levelling properties. Especially on surfaces with sidelight applications without visible overlap are possible. Because of a light hydrophobation of the first coat the open time of the second coat is extended. Therefore the application is mendable well.


The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
