The method
Grade and map the defects
Knots, checks and open cracks each fill differently. Consumption in character grades is a multiple of prime grades, which is exactly why waste percentage matters more here.
Fill deep defects properly
Large knots need a filler with body that cures without shrinking, a sunken knot in a finished floor is the most expensive rework there is.
Sand into the grain
Colour-matched filler sands flush and disappears into the grain, the character stays, the defect goes.
Finish as a system
Filler and coating must be tuned: adhesion of the finish over large filled areas is what makes a rustic floor read as premium. We develop this together with coating partners.
Why fills fail
Sunken knots
Shrinkage in deep fills shows weeks later, in the customer's living room.
Colour mismatch
Stock filler against fresh production wood: the repair announces itself.
Batch fallout
A board reworked after finishing rarely matches its batch again, the real cost is the board, not the putty.
Before and after: the difference the filler makes
Open knot in oak: filled with CosmetiWood MAX, sanded and ready for finishing.
More of the tree, none of the compromise.
Character wood filled and finished as one system is a sustainability story your architects can sell, and a margin story you can.
Common questions
Why is rustic parquet more expensive to produce than it looks?
The wood is cheaper, but filling volume is a multiple of prime grades, so filler performance (waste, shrinkage, rework) dominates the cost. With the right system, character grades still come out ahead: more of the tree is used and the product sells premium.
How do I sell rustic parquet against prime grade?
As character, not as compromise: more of every tree used (a genuine sustainability story for architects), a look prime grade cannot offer, and, with flawless filling and finishing, the same technical quality.
Does CosmetiWood work under natural oil and lacquer?
MAX and PRO are engineered for adhesion of finishing products on top of the fill. For rustic programmes we align the filler and coating as one validated system, ask us about coating partnerships.
Get this right on your own line.
Professional wood fillers, engineered to lower the true cost of filling: fewer rejected boards, less rework, a faster line.
