Industrial wood filling solutions

Better filling. Better products.
Lower production costs.

We develop and manufacture high-performance fillers for parquet, engineered wood and industrial panels. Combining our own formulation expertise with more than 30 years of machine building for the wood industry, we help manufacturers reduce defects, rework and total production costs.

The economics

Our filler costs more per kilo.
Your production gets cheaper per m².

The putty itself is less than 1% of the cost price of a floor. What decides the real cost of filling is what happens after: fills that shrink, break out or fail sanding, resulting in rework, disrupted planning and extra costs.

< 1%
of the cost price of a floor is putty. Waste and rework are the real cost of filling.

Why CosmetiWood

We understand the filler, the machine and the process

CosmetiWood grew out of CSP-Engineering, a machine builder founded more than 30 years ago and specialised in lines for industrial wood flooring. Our filler started as the consumable for our own PAR-Filler machines and grew into a full division with its own R&D and production.

01

Own R&D

Formulations developed in-house and adapted to wood species, production conditions and specific customer problems.

02

Own manufacturing

Our own production in Dessel gives control over quality, reproducibility, delivery and custom work.

03

Process expertise

Machine building for the wood industry is where we come from. Product and production process are designed to fit together.

04

Technical partnership

Support with colour matching, application, drying, sanding and process optimisation, on your own line.

The product

What makes a better fill

Bond with the wood

A very strong bond, so fills stay put through machining and sanding.

Non-shrinking

The defect stays filled after drying, without a second filling round.

Sandability

Sands flush with the wood, without smearing on the belt.

Finishability

Lacquers and oils bond to the filled surface, for an even finish.

Workability

Ready to use, no mixing, easy to spread by hand or to dose by machine.

Custom colours

Matched to blend in, or darker to make knots and cracks a feature.

What it delivers

Total cost of filling, with transparent assumptions

Our calculator compares the yearly cost of your current method with CosmetiWood: filler including waste, boards lost or reworked, labour and, for lines, the machine.

How our figures are built

  • Reference values (waste, rework rates, capacities) are averages from our 2026 market survey among parquet producers, not measurements at one customer.
  • "Rejected or reworked" counts every board that needs extra work after filling; not all of them are lost.
  • Savings are model results at 100,000 m²/year and €35/m². Every assumption is editable in the calculator.
  • Your own numbers come from a trial on your line, where we measure consumption, rework and speed together.
In practice

Invisible, or a feature. Your choice.

A filler matched to the wood makes the repair blend in; a darker filler turns knots and cracks into visible character. We make colours to order.
