Berger Penetrating Liquid

A clear penetrating solvent-based preparation for binding chalky, powdery surfaces that cannot be thoroughly cleaned.

Solve Potential Paint Problems

Chalking is the formation of a white, dusty powder on the paint film, and is actually a natural way for paint to breakdown as it weathers.

What are the possible causes?

Long-term exposure of paint film to the elements
Use of low-quality interior paint on an exterior surface
Over thinning the paint
Application of a thin paint film
Failure to prime and seal the surface before applying topcoat
Painting on a pre-existing chalky surface

What is the solution?

Remove chalk residue using a stiff bristle or wire brush
Wash with soap and water, and rinse thoroughly by hose or power washer
Allow surface to dry and check for any remaining chalk by running a hand over the surface
If noticeable chalk is still present, apply Berger Alkali Sealer or Berger Penetrating Liquid
If no chalk is present, repaint as normal
Repaint with a premium quality exterior coating
