The Product

[Translate to Chinesisch:] LOBADUR® WS Sealer FR

How to fireproof floors and stairways to meet class B1*

The innovative LOBADUR^® WS Sealer FR is a clear, two-component sealer for use with the trusted LOBA floor finish system. This product changes the fire performance of parquet and hardwood floors. Parquet layers, floor fitters, general contractors and builders can now satisfy applicable regulations for fire-resistant flooring. The requirements for wear layer thickness and floor thickness no longer apply. This is especially advantageous in renovation work, where floor thickness is often “critically” reduced by sanding.

The product is applied using the sandwich method:

1 x primer, 2 x Sealer FR, 1 x topcoat.

For retaining the natural colour of the wood
