Sopro GD 749 Universal Floor and Wall Primer

Application

Sopro GD 749 primer reduces absorbency and evens out variable suction in substrate. It stabilizes friable surfaces, binds loose particles and improves adhesion. GD 749 primer prevents pin-holes when self-levelling compounds are used, thus premature water loss is prevented where thin-bed tile adhesives are subsequently applied. For indoor and outdoor use.

Description

Light-blue, solvent-free, fast-drying, synthetic resin primer for high or variable suction substrates. For pretreatment of cement screeds, calcium sulfate-based screeds, board subfloors, gypsum plasterboard and gypsum fibreboard, lime/ cement render and gypsum plasterwork. Water soluble for application to high-suction substrates. Use Sopro GD 749 primer only in concentrated form with gypsum-bound substrates, calcium sulfate screeds or when used for priming prior to application of self levelling floor screed compounds.


Feature and benefits:

  • Fast drying.
  • Suitable for calcium sulfate screeds in one coat.
  • May be diluted with water to suit the application.
  • High penetration.
  • Suitable for floor heating systems.
  • Solvent-free.
  • EC1 PLUS very low emission PLUS.
