thematerials is assured. For contractors who wish to apply the
materials themselves Fosroc is also ableto offer technical

Section B : Application Method
1.0 Preparation
1.1 The concrete surface should be fresh and free of surface
water. Please ensure that there is noformations of bleed water
prior to commencing application.
1.1 For new hardened concrete, (after demoulding), the surface
should be wet before commencingapplication. Dry surface will prove
a problem in removing the curing membrane and will leavestains.
2.0 Application
2.1 Use knapsack type spray equipment for applying Concure LP90
and it will give a continuousand uniform surface appearance.
Maintain pump pressure to give an even spray.
2.2 Stir the material well before commencing application. By
stirring, there should be an evendispersal of the pigment.
2.3 The spray nozzle should be held at a distance of 450mm from
the concrete substrate andpassed back and forth to ensure complete
coverage.
2.4 There will be a fugitive white colour formation on the
application, which will help in recognizingthe applied areas.
2.5 The application should be continuous and should provide an
unbroken membrane.
2.6 Care should be taken that the surface is not trafficked
until the membrane dries completelyand the concrete attains its
trafficable strength.

3.0 Overcoating
3.1 Prior to overcoating always ensure that the curing membrane
is completely removed asit affects the bonding of the coating.
3.2 Although Concure LP90 will disintegrate with normal wear and
tear of trafficking andUV exposure, ensure that the curing membrane
is completely removed by jet blastingthe substrate with steam or
water.
4.0 Cleaning
4.1 Cleaning with water will remove the Concure LP90 from the
tools and equipment.
