Question 1

1. What’s the difference between fine surface filler and standard filler?

Accepted Answer

Fine surface filler has a finer particle size, making it better suited for finishing work rather than structural repair. It produces a smoother finish and is easier to sand back without clogging abrasives. Builders typically use it as a final skim over standard filler or patch repairs, especially when preparing a surface for decoration.

Question 2

2. Can I use fine surface filler on outside walls?

Accepted Answer

Most fine surface fillers are for interior use only. For external jobs, it’s better to use an exterior-grade filler with weather resistance.

Question 3

3. Do I need to prime the surface before applying fine surface filler?

Accepted Answer

Priming isn’t always necessary, especially for small touch-ups on previously painted or sound plaster. However, if the substrate is bare, highly porous, chalky, or dusty, a primer or stabilising solution may be needed to ensure good adhesion and reduce suction. Surfaces with uneven absorption can cause the filler to dry inconsistently. For best results, follow the surface preparation guidance on the filler’s packaging or data sheet.

Question 4

4. Is fine surface filler suitable for jointing plasterboard?

Accepted Answer

Some fine surface fillers are designed for jointing, and can be especially useful when a smooth topcoat is needed over taped joints. However, not all products are flexible or adhesive enough for taping and bedding. Appropriate fillers will be marked as suitable for jointing, and for best results, use a system where the base and finish coats are compatible.
