FAQs
Is Brummer Exterior Wood Filler suitable for indoor use?
Yes, while designed for exterior use and its waterproof properties are beneficial outdoors, it can also be used for interior repairs on compatible surfaces.
How long does the filler take to dry?
Drying time varies depending on the thickness of the application and ambient conditions (temperature, humidity). It is typically touch-dry within a few hours and can be sanded and over-coated once fully cured, usually within 24 hours for standard applications.
Can I use this filler on painted surfaces?
Yes, provided the existing paint is sound and well-adhered. It's recommended to lightly sand the painted surface before applying the filler for optimal adhesion.
What is the best way to achieve a seamless color match?
Choose the closest available wood color. For a perfect match, it's often best to lightly sand the dried filler and then paint or stain it to precisely match the surrounding wood or finish.
Is this product flexible after drying?
The filler is designed to be rigid like wood and does not contain significant flexibility. It is formulated not to shrink or crack under normal conditions.
Can I apply this filler over existing repairs?
It is best to remove any old, loose, or flaking filler or coatings before applying Brummer Exterior Wood Filler to ensure a sound base and good adhesion.
Does the filler require a sealant before painting?
No, the filler is designed to be applied under most decorative finishes, including paint. It does not typically require a separate primer unless your chosen paint system specifically requires it.
Troubleshooting
Filler is too hard to apply
Ensure the product has not been stored for excessively long periods or in extreme temperatures. If slightly dry, a small amount of water may be kneaded in, but avoid over-saturation.
Filler cracked after application
This usually indicates application in extreme temperatures or applying too thick a layer in one go. For thicker repairs, apply in layers, allowing each layer to become touch-dry before applying the next.
Filler did not adhere properly
The surface may not have been properly prepared. Ensure the area was clean, dry, and free from dust, grease, or loose material. Lightly sanding the surface before application can improve adhesion.
Color match is not perfect
Select the closest wood color and consider that the dried filler may appear slightly different from the wet product. For very precise matches, consider a light sanding and then painting or staining the filler to match the surrounding area.

Setup, Compatibility & Care
