    Can I Have A Decorative Concrete Overlay

    Yes, this replaced old carpet and tile in a hotel lobby.

    The project totaled 4500 sq. ft. of stamped and hand carved stones.

    The overlay material was a total of 1/4 inch thick over an old concrete floor.

    An excellent stampable overlay mix is STAMP MIX.

    This stamped concrete overlay was installed over an old, worn concrete patio that sloped towards the house.

    We resurfaced the concrete with our overlay, stamped a cobblestone pattern into it, and sloped the overlay away from the house to shed water.

    A spray down or sprayed on concrete overlay is great when you need some texture on the surface for slip-resistance or if you use a stencil to create a pattern like the one below.

    Concrete resurfacing using an overlay can make an old, cracked and pitted concrete patio look like new again.

    On this patio, I repaired the small cracks, lightly ground the surface, applied the overlay with a hand trowel at about 1/16 inch thick, then dragged a broom across the overlay to give it a broom finished look.

    I would use the trowel mix concrete overlay if you are going to diy this type of project.

    Add The Solid Crack Filler

    Assess the depth of the crack. If the crack is deeper than 1/4-inch, fill in the necessary sections to bring it up to a 1/4-inch depth. It is not desirable to use the liquid crack filler for deep areas as this extends curing time, can result in sinking filler, and adds to the overall cost of the project.

    One way to add solid filler is to dispense clean sand by hand through a funnel. One hand holds the funnel, while the other hand holds a small amount of sand and slowly drops it into the funnel. This method has the advantage of being very inexpensive and allowing you to vary the height of the crack filler as you go.

    Another option is to force a closed-cell backer rod into the crack. Three-quarter-inch backer rod is designed to fit into 1/2-inch cracks. Force the backer rod into the crack as much as you can with your fingers. Cut off the backer rod when you reach higher areas that do not need filler. If you reach sections where it is difficult to press the rod with your fingers, use a blunt tool such as a paint stirring stick, since sharper tools like screwdrivers may pierce the rod. Make sure that the backer rod is firmly in place before proceeding to the next step.

    What Causes Cracked Concrete

    How to Repair a Cracked Concrete Patio

    A cracked uneven concrete patio can be due to a number of reasons. One main cause is due to the soil beneath. The Dallas Fort Worth area is known for clay-based soil, which is highly expansive. The soil expands and contracts as it absorbs moisture. In turn, this causes the concrete to settle in various sections and often unevenly. This leads to sloping and eventually cracks.

    Insert Foam Tubing Into Large Cracks

    The crack I had to repair was about 1/2 inch wide.

    Although Sakrete crack filler can be used for cracks up to this size its best to fill in large gaps with the foam tubing.

    The foam tubing should be slightly wider than the crack to create a tight fit. I used a 5/8 inch wide variety.

    Place the tubing in the crack and push it down. There should be a 1/4 inch space between the top of the foam tubing and the top of the concrete crack.

    This 1/4 inch space is where the concrete crack filler will be poured.

    New To Real Estate From Framingham Ma

    If you’re still planning on having a concrete patio, rip that one out, and build a solid and even slab base to receive a new concrete slab. All those cracks on existing patio was caused by a poor slab base, and lack of any reinforcement . A new concrete patio needs to have a solid-compacted and even base in order to receive a new concrete flatwork that will stand for decades. Resurfacing any concrete surface is never the best option, eventually it will tip off, etc…

    In a situation like this one, the best thing to do, is to demo the existing concrete, build new base and place a new concrete patio, or use other type of material such as brick pavers to build your new patio. Do not place stones on top of it, you will have problems later. Hope it helps you.
