Tarmac Acrylic Primer – Water based primer with high bond characteristics
Tarmac Acrylic Primer – Water based primer with high bond characteristics. The primer is designed to give maximum penetration into the substrate in order to control suction and enhance the adhesion of cementitious flooring screeds and underlayments. Acrylic Primer has been designed to produce bonded floor systems using Tarmac flooring products. The primer dramatically reduces the suction of concrete substrates preventing premature drying.
- Controls the suction of concrete substrates to prevent premature drying issues
- Increases the adhesion of cementitous materials
- Non-toxic, safe to use
- High yield
- Compliant with the requirements of BS EN 13813
The primer dramatically reduces the suction of concrete substrates preventing premature drying.
All substrates must be clean, dry and structurally sound with no contaminants that could compromise the bond. Expose coarse aggregate over the entire area of hardened base by scabbling, planning or abrasive blasting. Where the substrate has a high relative humidity (above 75%) the use of Tarmac Epoxy DPM should be considered.
Installation of the product:
Tarmac Acrylic Primer is designed as a two coat system and should be diluted in the ratio of one part primer to three parts clean water (by volume). This mixture should then be applied using a soft broom or roller to the level where the substrate is suitably saturated but primer is not ponding. The initial coat should be left for a minimum of 24 hours before the installation of a second coat, applied using the same process. Tarmac Acrylic Primer should not be used on substrates with a temperature less than 6°C.
