Bona R590 is a one-component, silane-based primer/moisture barrier for priming and/or sealing the residual moisture in cement screeds or concrete (up to 5% CM / 90 % RH) before installing wooden flooring. It can also be used to reinforce weak subfloor surfaces up to a certain level.
Bona R590 is compatible with all Bona silane and polyurethane adhesives:
|Bona R848 Adhesive||An elastic, one-component, silane-based adhesive for installing engineered timber products or narrow solid boards|
|Bona R850 Adhesive||An elastic, one-component, silane-based adhesive for parquet flooring and most other types of timber products|
|Bona Titan||A hard-formulated, silane-based adhesive for all physically sound sub-floors|
Ensure that the substrate is sound, dry, clean and free from dust, dirt and any other surface contaminants.
Always do a test area before starting any project to assess product performance and suitability. Follow the manufacturer's instructions on the container at all times.
Before using the primer / moisture barrier the following climatic conditions must be met (values for Central Europe):
The product is protected by an aluminium plate, which must be removed together with little amounts of hardened material prior to use.
Please Note: The installation should be carried out within a narrow time frame to avoid dust forming on top of the primer. Very rough and porous subfloors can result in a higher consumption. If the floor is uneven, a suitable levelling compound can be applied.
