The most important part of mixing your patching material is through preparation. It goes for both new building construction and remodeling works.
The most common types of repairs are on flat surfaces, such as patios, driveways or walkways that have a hole or depression. The hole’s tapered sides can turn into a problem in the long run as the patch will deteriorate and can peel or fail due to the patching compounds thinning out. This can leave an ugly second area for you to repair again soon.
The best way to patch is by altering the sides of these holes. You can use either a hammer and a chisel or a circular concrete saw. It is critical that you wear eye and ear protection while undertaking this type of work as your eyes might catch small pieces of dust, concrete, or even masonry blades. Your ears could be damaged by the saw’s loud noise as well.
The most challenging part is for you to get rid of the taper from the hole’s edges. Now, if you are successful, the finished edges are almost unnoticeable.
Mixing the patching materials
You should always follow directions when mixing the patching materials. You would want your compounds to have the consistency a very thick gravy or of a cake icing. Never mix compound that will exceed fifteen to twenty minutes.
Applying the patch
If you’re not using any bonding agents, you should have to wet the surface that needs patching first when using water based repair compounds. On the contrary, you should follow all directions carefully if you are using a bonding agent.
For cases of deep concrete repairs, use hardened nails in the hole. For even deeper repairs, drill half an inch diameter hole and install a half an inch piece of reinforcing steel. These materials will make the patch stable and in place. Make sure that the steel reinforcements are at least half an inch below the top of the patch. You can use steel trowel, magnesium or wood float, etc. as finishing tools to finish your repaired area. Finishing requires practice as it is an art. Wait for a few minutes for the patching compound to begin stiffening to get your desired results. If you are not sure, you can always practice in some out of the way spots.
Cover the patch with a piece of plastic once you are satisfied with it. Put weights on the edges of the plastic so the wind will not blow it away and so that air won’t pass underneath the plastic. This is imperative! Make sure the plastic stays in place for three to four days.
The worst time to do this type of work is during a breezy, hot and sunny weather. Many people incorrectly think that this is the best time, but the patching compound will dry out too quickly. The ideal conditions to perform this type of work are in 55F weather or when it is overcast and damp. In case you have to do it in warm weather, you should do it early morning. Make sure that the repairs have enough shade to shield them from the sun.
Never repair concrete during freezing weather as the patches will instantly freeze and fail. Always use common sense when doing any concrete repairs.
