Professional Concrete Surface Preparation | Shot Blasting
surface preparation of concrete in readiness for the application
of a coating or repair material includes all the steps taken after
the removal of the deteriorated concrete. Many of the same steps
apply when little or no concrete is removed. Proper preparation
provides a dry, even and level surface free of dirt, dust, oil and
grease. Removal of surface contaminants allows primers and repair
materials to have direct contact with the substrate, increasing
the surface area and roughness of the surface, and providing increased
anchorage of the applied material.
Concrete Surface Preparation Basic Steps Include:
the concrete to remove all substances that could inhibit the ability
of the overlay to bond, such as dirt, oil and grease. It's also
necessary to strip away any coatings, sealers or paints that may
have been applied to the concrete.
any unsound concrete, such as minor spalling, scaling or delamination,
down to solid concrete.
active cracks so they don't mirror through to the overlay. Typically
any cracks equal to or wider than the width of a credit card will
or roughening, the concrete surface to improve the "grip"
of the overlay.
grinders or shot blasting units that mechanically abrades the concrete
is one of the most effective ways to prepare concrete substrates
for resurfacing. This equipment not only removes most contaminants
and unsound concrete, it will also leave behind a roughened surface
technologically-advanced floor preparation systems respects the
environment. No harmful chemicals are used in shot blasting, grinding
and polishing processes.
