Bona R410 DPM is a two-part epoxy resin, perfect for priming and strengthening weaker substrates as well as functioning as a highly effective moisture barrier on cementitious sub-floors where the relative humidity reading (R.H.) is as high as 90 - 100%.
Bona R410 is compatible as a primer with the following Bona 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|
Please view the Technical Information Sheet above, for a full list of compatible adhesives.
All substrates must be even, totally dry, clean, free from cracks and physically sound. The surface should also be slightly textured. If necessary it should be professionally prepared for laying.
Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the container at all times. The following climatic conditions must be met before using the primer:
The product in itself must, if necessary, be brought to room temperature. Warm product reacts more quickly whereas cold product reacts more slowly.
The hardener supplied is the correct proportions for the container of R410.
If Bona R410 DPM is being used as a primer, apply one layer of kiln dried sand onto the wet film (1kg per square meter). This will act as a key for a levelling compound to stick to, should it be required. If R770, R777 or R840, R850, R850T are to be used for gluing afterwards, the use of sand is not necessary.
Coverage should only be used as a guide as the actual coverage can be affected by how the product is applied and the substrate.
