Damages to concrete generally are repaired by filling them with a patch product. However, this won't work when the surface is vertical. Gravity will pull the patch down. To repair vertical concrete surfaces, a special product is used that starts as a liquid or paste, dries quickly and won't shift during repair.

Step 1. Widen the crack using a chisel and hammer to a minimum of ¼ inch and break away any deteriorating concrete (the edges of the crack should be vertical or beveled in an inverted “v”). NOTE: for vertical cracks less than 1/2-inch wide and for cosmetic repairs, the best option is to use a textured acrylic caulk. Step 2.

2012-9-27 · When selecting the grit on the sanding disc, you should look for a 24 or a 36 grit flexible disk. This will make the concrete smooth, but it will keep it rough enough so that the sealant will stick to the concrete. You will also need protective eye goggles and a face mask. Once you have your concrete sanding disc, you will need to attach it to ...

The expanded metal is left in place (unlike timber that is removed). The resulting rough surface provides a good mechanical key and requires no further preparation. For both horizontal and vertical joints, care must be taken to ensure that the layer of fresh concrete adjacent to the joint is adequately compacted.

The finer grits will result in ultra smooth and polished concrete surfaces. To prevent the floors from attracting dust and becoming rough again, high quality concrete hardeners are applied to the surfaces. For grinding new concrete surfaces, we may wait about less than a month to let it dry completely and cure properly.
