Applications

Wondertex Prem Filler is designed for interior plasterboard jointing and professional drylining applications where a smooth and reliable finish is required.

The plasterboard joint filler can be used for filling joints and gaps and for embedding jointing tapes, metal angles and corner reinforcements as part of a complete plasterboard jointing system.

Its smooth consistency and easy-sanding properties make it suitable for professional dryliners, plasterers and tradespeople looking for an efficient jointing compound for interior finishing work.

Suitable Substrates

Suitable for use on plasterboard joints, plaster and most common interior substrates. Surfaces should be clean, dry, sound and free from dust or other contaminants that could affect adhesion.

Mixing

Wondertex Prem Filler is supplied as a powder for mixing with clean water before application.

For a 12.5kg bag, use approximately 6 litres of water, giving a mixing ratio of approximately 1 part water to 2 parts powder.

Add the powder to clean water and mix thoroughly until a smooth, consistent and lump-free compound is achieved. Always use clean mixing equipment and prepare only the quantity required for the available working time.

Application

Apply the mixed compound to the prepared plasterboard joint, ensuring the joint is sufficiently filled. Where jointing tape is required, embed the tape into the compound and smooth the surface as necessary.

Further coats can then be applied as required as part of the chosen plasterboard jointing and finishing system.

Allow the compound to set sufficiently before sanding or applying subsequent finishing coats. Once ready, sand as required to achieve a smooth surface suitable for further finishing and decoration.

Working Time

Wondertex Prem Filler has an approximate working time of 60–90 minutes, providing sufficient application time while offering fast-setting performance to help keep plasterboard jointing projects progressing efficiently.

Working and setting times can be affected by site conditions, temperature, substrate and the quantity of material being mixed.
