Extended Product Information

FAQs

Can I use this filler on interior walls?

While designed for exteriors, it can be used indoors; however, ensure adequate ventilation during application.

Does it need to be painted?

Yes, for long-lasting protection against weather, the repair must be sealed with an oil-based paint or varnish.

Can I apply this in cold weather?

No, do not apply the product in temperatures below 5°C as it will not cure correctly.

Is this product waterproof?

It is water-resistant once cured and sealed, but it is not suitable for surfaces that are regularly under water.

How should I prep the surface?

Brush out all loose material and ensure the surface is clean, dry, and dust-free before application.

How thick can I apply each layer?

You should apply layers no more than 6mm thick to ensure proper setting.

Troubleshooting

The filler is not hardening properly

Ensure the application temperature is above 5°C and the area is shielded from direct rain or moisture.

Filler is shrinking or cracking after drying

You may have applied a layer thicker than 6mm. Apply in thinner, successive layers, allowing each to set fully in between.

Filler is popping out of the repair

Check that the surface was free of dust and loose debris before application. Re-clean the area and ensure it is dry before re-applying.

Pros and Cons

Pros

  • Convenient ready-mixed formula saves time
  • Strong adhesion to diverse building materials
  • Suitable for both wood and mineral-based surfaces
  • Easy to smooth and sand after curing
  • Nozzle allows for targeted application

Cons

  • Not suitable for areas regularly submerged in water
  • Cannot be applied when rain is imminent
  • Temperature sensitive (do not use below 5°C)
  • Requires oil-based paint or varnish for long-term protection

Setup, Compatibility & Care

Before starting, ensure the substrate is clean, dry, and free of loose material. For absorbent surfaces like porous stone or brick, lightly moisten the area first to prevent the filler from drying out too quickly. If covering nail heads, use an oil-based paint first to prevent rust bleed-through. After application, the filled area must be protected from rain until it is fully set and sealed with an appropriate exterior-grade oil-based paint or varnish. Keep the product stored in a cool, dry place and ensure the cap is securely replaced to prevent the remainder of the tube from hardening.
