Polycell Easy Sand Interior Filler - 10kg - White

The filler dries in approximately 3.5 hours per 5mm layer. However, this time can vary depending on temperature, humidity, and the depth of the area filled.

No, this product is specifically formulated for interior use only and is not suitable for outdoor applications.

It is suitable for a wide range of interior building materials, including plaster, plasterboard, wood, brick, and stone.

The filler remains workable for up to 1.5 hours, depending on ambient conditions such as temperature and humidity.

Clean tools and utensils immediately after use in warm water to prevent the filler from hardening on them.

Ensure the surface is clean, dry, and free from grease. Remove loose material. Seal highly absorbent or powdery surfaces beforehand and paint over rust-prone metal fixings with an oil-based paint.

Using two top coats can help reduce the visibility of the filled area through the paint, leading to a more uniform finish, especially on textured surfaces.

Ensure you are using the correct mixing ratio (2 parts filler to 1 part water). Use clean tools and mix thoroughly to a smooth paste. If too dry, add a tiny amount of water; if too wet, add a little more powder.

This can occur with very deep fills. Apply in multiple thinner layers, allowing each layer to dry before applying the next. Ensure the surface is not too absorbent and has been properly prepared.

Drying times are dependent on environmental conditions (temperature, humidity) and layer depth. Thicker layers or high humidity will increase drying time. Ensure adequate ventilation.

Ensure the filler is completely dry before attempting to sand. If it's still wet or partially cured, it will be gummy and hard to sand. Allow more drying time.

Ensure the filler is fully dry and has been sanded smooth. For very absorbent surfaces, consider applying a primer or sealer to the filled area before decorating.
