Frequently Asked Questions | FAQs

Why Proper Filling Matters Before Decorating

Filling is one of the most important preparation steps in decorating. Even minor surface defects can show through paint or wallpaper if left untreated. Using a suitable filler ensures better adhesion, a smoother appearance and a longer-lasting finish.

How to Apply Wall Filler for Best Results

1. Remove loose material and dust from the repair area.
2. Apply filler with a filling knife, pressing firmly into the defect.
3. Smooth the surface with light strokes to level it.
4. Allow to dry fully according to instructions.
5. Lightly sand if needed before painting or finishing.

What Is a Multi-Purpose Filler Used For?

Multi-purpose fillers are designed to repair a wide range of surfaces including plaster, wood, masonry and metal. They’re ideal for general maintenance and pre-painting preparation.

Do You Need to Sand Filler Before Painting?

Most fillers benefit from light sanding to create a smooth, flush surface, although some fast-drying products are formulated to minimise or eliminate this step.

Can Wall Filler Be Used on Wood or Concrete?

Yes, many multi-surface fillers are suitable for wood, concrete and other materials, but always check the product guidance to ensure compatibility.

How Long Should Filler Dry Before Decorating?

Drying times vary depending on depth and product type. Always allow the filler to cure fully before sanding, painting or applying further coatings.

Why Does Filler Crack or Shrink?

Cracking can occur if filler is applied too thickly or dries too quickly. Building up in thinner layers helps create a stronger, more stable repair.
