Concrete Surface Preparation and Coating Removal Contractor
Laying a Foundation for Years of Trouble-Free Service.
As many as 80% of floor coating failures result from inadequate surface preparation.
McLean Flooring Solutions brings years of training and experience in surface preparation to every job.
Removal of existing coatings, surface prep and possible moisture mitigation are also often required prior to tile or carpet installation.
We rely on a variety of materials and methods — analyzing surface, intra-surface, and subsurface conditions, and factoring in budgetary and regulatory realities and environmental concerns — to create the best solution for your resurfacing job.
HERE ARE SOME OF OUR BASIC PREPARATION STEPS:
EXAMINE THE SURFACE
We’ll check the surface for barriers such as existing sealers, curing materials, grease, oil, efflorescence, and dirt that must be removed.
If appropriate, we send out old tiles and adhesives for lab testing of hazardous materials to protect your workers and ours.
EVALUATE PAINTED SURFACES
If paint is peeling or degrading in any way, it must be completely removed.
REPAIR SURFACE DEFECTS
Remove any loose concrete, clean and fill holes and cracks, and address other surface defects.
Typically, for example, we V-cut all cracks and fill expansion joints and cracks with a flexible polyurea, while addressing spalls with a solid concrete repair product.
TEST THE CONCRETE
A “water drop” test can be used to determine if a surface has any pre-existing sealers that would inhibit adhesion. We use Wagner Electronics “Rapid RH” concrete moisture tests to determine the amount of moisture vapor in your floor.
This test is critical and will determine which primer we use to avoid future coating failure.
CLEAN UNCOATED CONCRETE
Remove any chemicals, oil, grease, or other foreign substances.
HERE ARE SOME TECHNIQUES WE EMPLOY TO CREATE AN IDEAL BONDING PROFILE ON CONCRETE
Shot-blasting is the preferred method for creating an ideal bonding surface for epoxy, polycrete, and Methyl Methacrylate (MMA) floors.
Shot-blasting triples the bonding surface profile for a seamless floor.
Diamond grinding is done to the edges of a floor or in open areas and is excellent for smoothing out a rough, uneven floor.
Scarifying employs cutters (toothed washers) operating with a rotary action. The cutters impact the concrete surface at a right angle, fracturing or pulverizing the top surface of the concrete and exposing a clean, fresh surface.
