Easy Process Of Fixing Cracks In Concrete Block Walls
Cracks in concrete can be wide as well as narrow, both of which need to be fixed as soon as you notice them. Wide concrete cracks can be mended or strengthened with a patch as well as sealed using a concrete patching compound. Smaller cracks, not more than 1/4 inch wide, can be fixed with the help of a concrete caulk or liquid filler. Patching compounds generally are combined & put together with water and then they are spread using a trowel. They have a texture exactly the same as grout that can be smoothed as well as textured in order to blend with the surrounding area. However, the color of the patch will appear like new concrete that will not match the old concrete. Covering up the patch fully needs painting the surface using suitable concrete paint.Fix Wide Cracks In Concrete Block Walls
- When it comes to repairing wide concrete cracks, you need to weaken or undermine the sides of the crack in order to give it an inverted "V" shape. This, in turn, will help the repair material to "key" into the crack, building a mechanical bond, apart from the chemical bond betwixt the patch material and the concrete.
- First of all, rip off the crack with the help of a hammer as well as a masonry chisel in order to open up or broaden the base of the crack as well as to get rid of any loose material from the old concrete.
- After that, it is important to do away with all the debris from the crack, with the help of a wire brush. If you want, you can also clean the crack with the help of a pressure washer or a garden hose and spray nozzle.
- Take out all water as well as debris from the crack with the help of a wet/dry shop vacuum or a brush. Work with the utmost care when it comes to getting rid of all dust and grit from the crack. Don't worry if the surfaces are wet, however, make sure to avoid pools of water on the surface.
- Combine & put together the concrete patching compound, in accordance with the manufacturer's directions. Chisel the compound into the crack. Run through the chisel into the compound in order to get rid of air pockets and help move the patching material extremely deep into the crack. Fill the crack up to the adjoining concrete surface.
- Smooth the surface of the patch with the help of a trowel, beautifying the compound into the adjoining concrete. Brush the surface of the patching compound with the help of a dry paintbrush in order to texture the surface, if you want.
- Allow the compound cure as directed before painting or sealing the surface of the patch and the adjoining area, if desired.
