In general for substrates such as wood, concrete, mortar, fibre cements board, Eternit, etc. Also to be used as a blocking primer on bituminous substrates
In general, to be used for applications where highest water resistance is required such as swimming pools, fitness centres and underground joints. The drying time of Primer P87 at +20°C is at least 60 minutes. Latest 4 hours after primer application, the application of sealants or adhesives has to be performed. After longer drying times the surface should be controlled for cleanness. Primer P87 can also be used as blocking primer on bituminous substrates. For less absorbent substrates we recommend to dilute Primer P87 with Xylol up to 25% or use Primer 83. Primer P87 is moisture sensitive. Immediately close the canister after use. May leave stains which are difficult to remove from the substrate. Do not wait until residues are dried up; remove and wipe off immediately.
