Flow Primer

Product description

Brush-on primer for surface pretreatment before floor levelling. Flow Primer improves the adhesion of floor levelling compounds, reduces or eliminates the formation of air bubbles, and prevents water contained in the floor levelling compound from being absorbed into the surface too quickly.

Applications

  • Hollow-core slabs
  • Cast-in-place concrete floors
  • Cement-based levelling compounds
  • Plasterboards and chipboards
The product is suitable for use on sites with a Nordic Swan Ecolabel.

Instructions

Pretreatment of the base
  • Remove dirt, dust, cement paste and all loose material from the base
  • If necessary, perform machine grinding, centrifugal blast cleaning or diamond grinding
Mixing ratio
  • Concrete surfaces and surfaces with cement-based levelling: 1 part Flow Primer, 3 parts water
  • Surfaces that cannot withstand moisture, e.g. plaster and wood surfaces: Use undiluted
  • Mix before use by swirling the package; avoid shaking
Applying the primer
  • The Primer is applied as a thin, even layer by brushing
  • The Primer must be dry before the floor levelling compound is applied (1 to 4 hours, depending on the conditions)
  • Highly absorbent surfaces (e.g. cast-in-place concrete floors) are primed twice.If air bubbles form in the surface of the floor levelling compound, it usually indicates insufficient priming
  • Wash tools and equipment with water immediately
