Product Description

Regardless of what materials you need to prime for your projects, the Bostik Cempolay Universal Primer Blue is there for you. This solvent-free, water-based, acrylic product is a bonding and priming agent that is best used before you apply any levelling compound to ensure that it levels out as smoothly as possible. When the primer is applied without dilution on non-porous surfaces, it can act as a bonding agent that can be used on ceramic tile, power-floated concrete, rigid metal, quarry tile, asphalt, terrazzo and surface membranes. When it is diluted, the primer can be applied to porous surfaces.

+ Delivery & Returns
  • PREPARATION :
  • Ensure the subfloor is clean, sound, dry and free from contaminants that may hinder adhesion.
  • Can be used over traces of old adhesive residues providing that they are well bonded and non-moisture soluble. However, it is not suitable for use over tackifier, bituminous or watersoluble adhesives which should be completely removed.
  • The subfloor should be tested in accordance with British Standards, using a properly calibrated and insulated hygrometer.
  • A reading of 75% RH or less confirms that the subfloor is satisfactorily dry. Where this has not been attained, it is necessary to apply a Cempolay surface membrane to suppress residual moisture. For further information contact Flooring Technical Services.
