FAQs

Can I use this primer on exterior walls?

No, this product is specifically formulated for internal applications.

Do I need to sand the surface before applying?

Yes, light sanding is recommended for existing finishes to ensure maximum adhesion.

Is this primer safe for new plaster?

Yes, it is excellent for preparing new plaster, provided it has been allowed to dry/cure properly.

How many coats should I apply?

Usually one coat is sufficient to provide a uniform base, depending on the porosity of the underlying surface.

What is the primary benefit of the grey finish?

The grey colour provides a neutral base that helps improve the opacity and depth of your final topcoat.

Troubleshooting

Poor adhesion to the surface

Ensure the surface was thoroughly cleaned of dust, grease, and loose debris before application.

Primer is showing through the topcoat

Check that the surface was sufficiently prepped and that you have applied the recommended number of topcoats.

Stiff brushes after use

Ensure thorough cleaning with warm soapy water immediately after finishing; do not allow the product to dry on tools.
