The only filler you can sand and varnish like wood
Pattex AC 411 is a water-based synthetic polymer sealant filler with a matte finish, specifically formulated for woodworking and parquet. Its difference compared to any other sealant in the range is that, once dry, it can be sanded, painted, and varnished. This allows for finishing a cabinet front or a parquet joint so that the varnish flows over it without the joint being noticeable.
FIVE WOOD TONES: oak, sapele, beech, pine, and cherry. Choose the tone before applying; combined with subsequent sanding, the joint practically disappears completely.
Why choose AC 411 Wood
- ✓ Sandable: allows the joint to be flush with the wood surface, which conventional silicones and acrylics do not permit.
- ✓ Paintable and varnishable: accepts water-based and solvent-based finishes once dry.
- ✓ Matte finish: does not shine or reveal the joint under grazing light, unlike silicones.
- ✓ Skin formation in 5-10 minutes: very fast, ideal for serial work in the workshop.
- ✓ Water-based, odorless: tools and residues are cleaned with water only.
- ✓ High adhesion on wood, laminates, metals, and construction substrates.
