Apply an even film of the mixed adhesive to both surfaces
by brush, roller coater, serrated scraper or spraying.
In some cases a single adhesive application to each
surface may not be sufficient (e.g. porous surfaces) then
multicoat applications may be needed to build up film
thickness. In this case, each coat should be allowed to
dry for about 40-45 minutes except the final one which
should have 10 - 20 minutes. It is always advisable to
build up film thickness with a number of thin coats rather
than a single heavy coat.
Allow the 2 films to dry for 10-20 minutes, or until they can
be touched with the knuckles without any cement being
