PVA pretreatment

PVA pre-treatment

So that design panels are suitable for PVA pressing (bonding with white glue), depending on the material, they must either be pre-treated on the back side through an additional production process at SIBU DESIGN or manually sanded, i.e. roughened.

When is manual pretreatment necessary?

Depending on the product:

In the technical spreadsheet of each product you will find if a pre-treatment is necessary at all, as well as the information if SIBU DESIGN offers the decorative panel already pre-treated. If you order the product already pre-treated, you will see the abbreviation “PVA” in the product name, which highlights that the sheet has been pre-treated.


A decorative panel pre-treated by SIBU DESIGN must be pressed within 2 months, otherwise the industrial treatment (not visible to the naked eye) will decrease and must then be roughened again manually with a sander.
