Thanks to its advanced bonding properties, concrete resurfacing can last for quite a while. A properly resurfaced floor can last from 8-15 years.

Concrete resurfacer is a very strong product, rated for a compressive strength of about 4,500 psi. This is actually stronger than the slab itself, so properly applied, resurfacing layers can be very durable.

Concrete seems like a stable and permanent material, but it remains porous and will absorb water. When this water trapped inside the concrete freezes, it pushes the cement binder apart. This expansion, and the resulting contraction when the water melts again, causes crumbling.

Yes, you may pour a concrete pad overlay over an existing slab. You need to consider the added height and weight of the overlay on the existing structure. Overlays may include polymers, portland cement concrete, or epoxies. … You should improve the drainage of the slab by having a good slope on the overlay.

Repair Crumbling Concrete. Concrete is simply artificial rock. If it’s mixed, placed, finished and cured correctly it can last 100 or more years. … To add a thin patch of concrete that wouldn’t exceed 3/8-inch in thickness, all you do is mix coarse clean sand with Portland cement.

Fact: Fresh wet concrete does not normally bond well to existing dry concrete. … Concrete would have gotten an F. There is nothing in basic portland cement that will act as a bonding agent. Portland cement concrete works well in mass and provides great compressive strength but not bond.

Do not try to use concrete to glue the pieces back together – it won’t work, so don’t waste your time. … Once you have the epoxy glue correctly mixed, simply apply it to the damaged areas, clamping them together until the glue is completely dry.

Concrete Resurfacing Costs. The average cost to resurface 100 square feet of concrete is $400. Less expensive projects can run as little as $300 while more expensive ones are about $500. … Concrete with a decorative overlay typically ranges in price from $7 to $12 per square foot while stamped concrete costs $8 to $20.

Pour the resurfacer onto the concrete in one-foot wide strips. Scrub the material into the concrete surface using a long handled squeegee. Evenly spread the resurfacer back and forth onto the slab. Apply a non-slip finish using a concrete broom after about 5 minutes.

Cement sticks very well to plastic, or at least Portland cement concrete does. Leave a little residue in a plastic paint bucket, on a plastic tool handle, or on any other plastic surface, and try to get it off a few days later.
