REMOVING MASTIC FROM CONCRETE I have had many requests for a
painless method to remove tile mastic from a concrete floor so I have researched
the answer. Mastic of course is the adhesive used in applying tile, linoleum and
carpet and those that have attempted to remove it manually can verify that it is
meant to be permanent. You'll find it common in older houses that are being
renovated. If you attempt sanding it or grinding it using conventional tools you
will simply plug up your paper or stones with the glue and then smear it with no
result. Using chisels, hand scrapers and solvents to break down the glue is not
very efficient and very tedious. The method that professionals use is a machine
known as a Concrete Floor Grinder. Similar to a floor buffer, this machine has
diamond cutting blocks that grind and level and smooth concrete, remove epoxy,
urethane, polymer enhanced surfaces, glue, thinsets, mastics, brick, grout,
& paint. But
if the material to be removed can be cut with a knife
and is thicker than 1/16, as with mastic, a blade called a "Strip-Sert" is
substituted for the diamond inserts. Strip-Serts are tungsten carbide inserts
designed to remove heavy build up without damaging the concrete. The Strip-Sert
has four beveled edges. Each edge is rated to last 2 to 4 hours (or 500 to 1000
sq. ft.) Strip Serts are ideal for removing heavy mastics, paints, resins, tar,
fiberglass, ice, industrial buildups and rubber deposits. Applying clean sand to
the surface before grinding will cause the mastic to ball up and make removal
even easier. Strip-Serts will only strip these coatings and will not damage the
concrete floor. Keeping this in mind, sometimes coatings will sink into the top
layer surface of the concrete and diamond blocks will need to be used afterwards
when a clean concrete finish is desired if you are not installing another floor
covering.
