SILRES^® BS 1306

SILRES^® BS 1306 may be added undiluted to aqueous masonry coatings and primers either during after manufacture. We recommend adding 1 wt% to masonry coatings and 5 wt% to primers.

SILRES^® BS 1306 can also serve as a water-repellent primer, in which case it should be diluted 1:9 parts by weight with water. When such primers are required to strengthen the substrate, we recommend adding a polymer dispersion in hydrosol form.

For the impregnation of insulating materials, we recommend diluting SILRES^® BS 1306 with water in the ration 1:100 to 1:200 parts by weight.


SILRES^® BS 1306 is an additive used in the manufacture of aqueous masonry coatings and aqueous primers to enhance water repellency, water resistance and water-vapour permeability. It also improves the processability and antiblock characteristics of the aqueous coatings.


Suitable for:

• silicone resin emulsion paints and silicone resin plasters
• silicate emulsion paints and plasters
• highly filled emulsion coatings
• whitewash emulsions
• stoppers
• reinforcing stoppers
• aqueous facade primers
• insulating materials

SILRES^® BS 1306 may also be thinned with water for use a water-repellent primer on material substrates and as a water repellent for in-plant manufactured insulation materials.
