Uses

Bonding all size and formats of jointed, pre-finished solid wood parquet with a ply backing. We advise against laying varnished, pre-finished solid wood in the lower part or traditional solid parquet without tongue and groove.

Recommendations when using Mapei Ultrabond P990 1K – Moisture curing, resin-based adhesive:

• Before laying, make sure all rooms have suitable windows or other sealing systems.
• The humidity level in the screed must be according to current norms and standards.
• If the substrate is not completely dry, or if the humidity is higher than the recommended level, we recommend applying a coat of suitable waterproofing primer, such as Eco Prim PU 1K, Primer MF, Primer MF EC Plus, etc.
• If there is a risk of rising damp, a vapour barrier must be laid before installing the screed.
• The humidity level in the wood must be according to current norms and standards.
• Do not lay if the temperature is lower than +10°C or higher than +35°C.

• Only lay floors if the walls and floors in the room are completely dry.
• In particularly dry weather, the hardening time of the product is longer.
• Do not let the product come into contact with fresh two-component epoxy-primer, otherwise it will deteriorate.
• Non-absorbent surfaces such as ceramic and marble must be sanded or cleaned and then treated with Primer M.
• Apply a coat Primer M on metallic surfaces
