CelluBOR Adherence Enhancing Primer

CelluBOR Adherence Enhancing Primer


Used as a multi-purpose primer to improve adhesion to absorbent and impervious surfaces. Because CelluBOR increases the adhesion of the surface being sprayed, it is also used on cement-based screeds, calcium sulfate screeds, mastic asphalt screeds, leveling screeds, concrete floors, stone floors, wood floors, gypsum floors, and ceramic floors. The coating materials can be used as a primer before bonding with dispersion or polyurethane adhesives.



  • Density: 1,05 gr / cm3
  • Drying time: at least 1 hour before applying CelluBOR
  • Drying time: at least 1 hour before applying CelluBOR
  • Calcium sulfate, for wood, surfaces at least 2 hours before direct bonding.
  • Approximately 2 hours if solvent-based and dispersion adhesives are used on absorbent substrates.
  • About 12 hours if polyurethane adhesive is used.
  • After curing, it can withstand temperatures up to 500C.
  • Fast build-up
  • It has a high cover power and concentration.
  • Versatile in use
  • Suitable for use under wood veneers.

The substrate must be clean, dry, free from cracks, sound, and load-bearing, free from dust, grease, and debris. Calcium sulfate, tiles, natural stone, terrazzo, wooden surfaces should be sanded and cleaned with a vacuum cleaner. The material should be mixed well before use. On absorbent surfaces, the material is diluted with water in a ratio of 1:4 and applied with a roller. On porous and highly absorbent surfaces, it may be necessary to apply a second coat of primer after the first coat has dried. On concrete surfaces and impermeable surfaces, dilute the material 1:1 with water and apply with a roller. Be sure to feed the material properly and avoid puddles of water during application. It is important that you observe the drying times given in the technical data if you apply the material directly. They depend on the absorbency of the dry surface and the relative humidity. While drying time is shortened at high temperature and low relative humidity, it is lengthened at low temperature and high relative humidity. It should not be used under elastic wood coating adhesives. It should not be applied when the soil temperature is 150C and the soil moisture is above 75%. No substances other than clean water should be used to dilute the product.
