PP10 Pur Primer

Description

PP10 PUR Primer is a single-component polyurethane primer used to improve the adhesion of PU sealants, adhesives and foams on porous and non-porous surfaces such as concrete, stone, wood, plaster and metal. It penetrates and strengthens the substrate to ensure a durable, long-lasting bond.

• The surface must be clean, dry and bearing and free of any residual material and movable parts
  that would prevent adhesion.
• Old coatings, oil and dust must be fully removed from the surface. Sharp points should be
  coved; areas that are suitable for cracking such as vertical/horizontal joints should be angled.
• Open a V-shape section at the area there are cracks on the surface and fill with polyurethane
  sealant.
• Wait minimum 28 days for fresh concretes
• For a single layer of application, 200-250 g/m2 is recommended. If you are not sure of the floor
  strength, we recommend applying two-layer of Primer.
• Primer ensures a reliable and sound application of PU waterproofing coating.
• Primer is applied by a brush or roller until the whole surface is covered. For larger spaces, it is
  possible to apply by spraying with an airless pump.
•  Clean all tools and application equipment with thinner immediately after use. Hardened and/or
  cured material can only be removed mechanically
