Primafloor is a single pack polyurethane acrylic primer for all new and unfinished or stripped wooden floors.

Available in Clear and 6 colours, Primafloor strengthens the durability and performance of all water-based varnishes, both single and two pack, thereby ensuring optimum performance of the finish coat.

Primafloor also prevents tannin bleed and avoids gluing of the wood strips and joints by the finish, while also being odourless, quick drying, light fast and non-yellowing.

Ideal uses for Primafloor

  • Primafloor is perfect for all soft and hardwood floors including exotic hardwoods, parquet flooring, veneered flooring and staircases.
  • Primafloor’s range of colours can be intermixed or added to the finishing product to achieve the desired look.
  • Compatible with all types of waterborne floor varnish (1pk and 2pk).
  • Colours can be mixed with Oleofloor and Vegafloor.

Always read the Primafloor Product Information before using and follow the instructions carefully.

Surface Preparation

General directions:

Surfaces must be dry, clean, free of dirt, grease and other surface contamination including previous coatings.
Primafloor can only be applied to bare wood surfaces.
ALL other finishes MUST be completely and thoroughly removed.
Always clean meticulously with a vacuum cleaner after each sanding, including any dust traps (skirting, radiators, pipes, window sills, etc).
Sand wooden floor using appropriate system and abrasive grades, depending on condition of surface and wood species.
Use an edge sander for edges, a mechanical hand sander, chisel or scraper for corners.
Cracks of 2 mm wide or less should be filled with Lianfloor and sanding resumed with 80 or 100 grit paper depending on the last grit used.
Finish with finishing grade up to grit No. 120 or 150 depending on the wood species and thickness of wear layer.

Sanding grades

(change only one sanding grade at a time):

Course Grades: 24, 30, 36
Medium Grades: 40, 50, 60
Finishing Grades: 80, 100, 120, 150

New Wood Surfaces:

Degrease surface with denatured alcohol, acetone or similar solvent based product.
Prepare and sand surface as instructed in “General Directions” above.

Previously treated surfaces (oiled or polished):

Previously oiled or polished surfaces should be dry stripped with DSP 800.
After stripping degrease surface with with denatured alcohol, acetone, white (mineral) spirit or similar solvent based product.
Prepare and sand surface as instructed in “General Directions” above.

Previously coated surfaces (varnish, paint, stain):

Remove existing finish by sanding or stripping with DSP 800.
After stripping degrease surface with with denatured alcohol, acetone, white (mineral) spirit or similar solvent based product.
Prepare and sand surface as instructed in “General Directions” above.


  • Facing the light and starting opposite the door so as to work towards it. Apply an even and generous coat of Primafloor ensuring a uniform level of timber saturation to avoid colour variation. Always maintain a wet edge to avoid overlaps.
  • Start with a brush at the edges, then do the remaining surface working in areas of 2 metres by 2 metres.
  • Allow to dry for 2 hours depending on the ambient conditions.
  • For exotic hardwoods or woods high in tannins a 2nd coat of Primafloor may be applied. This provides a greater seal against tannin staining and bleed.
  • To accentuate a colour a 2nd coat may be applied 2-8 hours after the 1st coat.

Clean up

All that is required for clean up is water.

Things to remember

  • Protect everything that does not have to be coated.
  • Remove all furniture and furnishings.
  • Remove plants and flowers. Remove or cover fish tanks.
  • Mix carefully before application. Do not shake.
  • Use as is. Do not dilute.
  • Do not apply at an ambient air and wood temperature of less than 10°C or greater than 25°C.
  • Only apply Primafloor to wood surfaces whose moisture content is 15% or less.
  • Never sand primed or stained wood prior to applying the finishing coat.
  • In all cases, comply with the applicable standards.
  • To avoid product drying to fast do not open windows during application of Primafloor.
  • Primafloor colours may be mixed with a maximum of 10% Primafloor colourless or water to create a translucent stain.
