Paint a PVC floor properly

A floor made of PVC wears off over the years and then looks ugly and sometimes even dirty. After painting, the floor can shine in fresh luster and appear as new again for a few years.

Special PU paints

The most important requirement for a durable and good result is the type of paint used to paint a PVC floor. The chemical industry has developed special floor coatings with the required durability and load capacity.

The basis used in most paints identified as PVC floor paints is a urethane-acrylate dispersion. This type of paint can be diluted with water and contain additional hardeners. The manufacturers offer the special paints, also known as PU paints, in fast-drying versions.

Extensibility and elasticity

For painting a PVC floor, the coating compositions must have a high level of resistance to abrasion and high levels of abrasion resistance. Each time you enter the PVC floor, the elastic substrate will give way and the paint must follow these movements without tearing.

The extensibility is called the ultimate elongation at break and should be at least 200 percent for the products used. Special manufacturers usually show 300 to 400 percent elongation at break. This property must also be maintained under different temperature conditions, which can be read by specifying the toughness and the temperature range.

processing types

The application of the paints on a PVC floor can be done by painting, but also the spraying or rolling up is possible. For absorbent PVC with a porous surface, painting is recommended in order to "saturate" the surface visually.

Step by step guide to painting a PVC floor

  • Plastic cleaner or acetone
  • primer paint
  • PU paint
  • possibly additional hardener
  • cleaning fleece
  • Sandpaper 400 grit
  • Brush, roller and / or spray gun

1. Clean

The absolute absence of grease and dust is achieved by thorough and repeated wiping of the PVC surface. Do not use soap-based cleaners.

2. Grind

Sand the surface evenly crosswise using fine 400 grit sandpaper. After sanding remove the sanding dust completely with the special cleaning fleece.

3. Priming

Apply the primer coat thinly and evenly in the color of the later coat. Work with brush and roller and pay attention to the "leveling" of all grinding grooves when brushing. Allow to dry for at least 24 hours.

4. First coat

For a very hard and smooth surface it is possible to apply the paint with a spray gun. It is safer to paint with a brush and roller, which may compensate for porous or leaky areas.

5. Second to last coat

As with all strokes, the thinner the layers are applied, the better the result. It's better to plan a third and fourth round with at least eight hours of dry time in between.

Tips & Tricks

Test painting in a hidden place, let the paint dry out and stick a transparent tape on the spot. If no paint residues are visible on the adhesive tape when peeling off, the paint is resistant to abrasion.
