Toupret Exterior Filler 5kg - White

Yes, although it's an exterior filler, it can be used on interior surfaces like plaster, concrete, and painted walls due to its durability and adhesion properties.

The filler sets to a hard finish typically within 24 hours, after which it can be overcoated. Full hardening may take slightly longer depending on environmental conditions.

You can overcoat with any water-based masonry paint or mineral paint after 24 hours. For solvent-based polyurethane or epoxy paints, apply a water-based exterior paint primer first.

No, Toupret Exterior Filler is formulated to be extremely durable and sets to a rock-hard finish with no depth limit, meaning it should not shrink or crack.

Store any leftover filler in its original, tightly sealed container in a cool, dry place. Protect it from frost.

The product description does not explicitly mention wood, but it is suitable for a wide range of substrates including stone, brick, concrete, and painted surfaces. For specific wood applications, testing in an inconspicuous area is recommended.

This can happen if too much water was used during mixing or if the surface was not properly prepared. Ensure you follow the recommended water ratio and that the substrate is sound and clean.

Ensure the surface is free from dust, grease, and loose paint. For very smooth or non-porous surfaces like glazed tiles, a light sanding might improve adhesion, or ensuring the surface is slightly damp can help.

While Toupret Exterior Filler has no depth limit, excessively thick applications might benefit from being built up in layers, allowing each layer to become firm before applying the next, especially in very deep voids.
