PENOSIL
Premium BetPrimer bonding dispersion for priming concrete surfaces

Values

• Water-based, emits no odours or hazardous compounds.
• Provides good bonding on all concrete, brick and plaster surfaces, natural stone, drywall or other building tiles.
• Simple application.

• Dries quickly.
• Elastic and resistant to tensile and compressive stress.

USAGE INSTRUCTIONS

Floors: Primer diluted with water 1:5 up to 1:20 (dispersion : water). For example, for priming floors before applying screed mixtures, at a ratio of 1:3 to 1:5; layers of concrete, manually squared floor screed mixtures for strengthening and enhancing wearing resistance at a ratio of 1:5 to 1:20; for strengthening concrete floors at a ratio of 1:5 to 1:10. Concrete or screed mixture may be applied immediately on top of a moist adhesion substrate. Allow the primer to dry for 2 hours before covering for ceramic tiles, non-absorbent surfaces and substrates that contain traces of old glue. In case of parquet glued to substrate and floor heating systems, all concrete floors must be sanded to clean them completely of any bleeding and other substances that may prevent bonding (e.g. traces of old glue). Only levelled areas should be primed.

Walls and ceilings: Primer diluted with water 1:5 up to 1:20 (dispersion : water). E.g. strengthening plaster at the ratio of 1:5 to 1:20; improving the adhesion of cement-based grout: 1.5mm – 1:5 and 5-20mm – 1:10; for strengthening weak surfaces at a ratio of 1:15 to 1:20. Use undiluted concentrate in case of non-absorbent substrate. Apply primer to the treated surface as a thin, uniform layer; there must be no puddles of adhesion substrate.

TIPS

• Clean the substrate of all dust, loose parts, grease and anything else that could impede the adhesion of the primer.
• Product is applied on the substrate with a cleaning brush or a paintbrush in two layers.
• Coverage depending on the substrate 3-10 m²/l.

LIMITATIONS

• Air temperature during use from +10 °C to +30 °C.
• Maximum relative humidity of the surface: wood 8-12% and concrete <80%.
