Dulux Trade Weathershield Exterior Flexible Filler - 450g

A lightweight exterior filler from Dulux Trade, Weathershield Exterior Flexible Filler is easy to use and specifically formulated for use on wood and masonry with the Weathershield paint systems. Flexibility and adhesion are both excellent, making it resistant to cracking and shrinking. It's also easy to rub down smooth when dry, ready for painting.

• Easy to sand
• Excellent flexibility
• Resists shrinking and cracking

For the best results, ensure surfaces are clean, dry and free from all defective or poorly adhering material.

Thinning is not required, but adding a few drops of clean water and mixing to a stiff paste may make it easier to use.

• Dampen the area to be made good, using a clean damp sponge
• Press the filler firmly into the defect using a clean filling knife. Leave a small excess of the filler to allow for any sinkage
• Rub down smooth when dry, drying time will vary, depending on the depth of repair and will be significantly longer in cold, damp conditions. Allow at least overnight before rubbing down.

Do not use Weathershield Exterior Flexible Filler with varnish systems or as a fine surface filler or for major repairs.

Note: always follow the manufacturer's instructions on the tin

Q. Does Dulux Trade Weathershield Flexible Exterior Filler give weather resistance?

A. This filler is formulated to withstand various weather conditions, including rain, snow, sunlight, and temperature fluctuations. It remains flexible even after curing, allowing it to expand and contract with the substrate without cracking or losing adhesion.

Q. Is Dulux Trade Weathershield Flexible Exterior Filler paintable?

A. This filler is paintable, meaning you can easily blend it with the surrounding surface. Once the filler has fully cured, you can paint over it to match the colour and finish of the surrounding area, creating a seamless appearance.

Q. Why do I need a flexible filler for exterior applications?

A. The flexibility of this filler is essential for exterior applications because outdoor surfaces are constantly subjected to movement. Whether it's due to temperature changes or structural shifts, the filler can flex along with the substrate, reducing the risk of cracking or detachment.
