Yes, you’re probably tired of hearing it, but preparation is everything! Once the application surface has been degreased (when necessary), cleaned, and properly profiled, you will need to repair any cracks or holes before applying MuscleGloss. This part is crucial for two reasons. First, if you do not repair cracks and holes, your epoxy is going to seep into them, which will cause you to use way more product than expected” possibly even running out of product if the cracks/holes are deep. Second, you will want to make sure the repairs you make will be solid. A failed patch can easily turn into a failed epoxy application, because the epoxy can and will come up with a patch that doesn’t stick.
There are two kind of cracks you need to keep in mind, those that are less than 1/8” in width and depth and those that are greater than 1/8” in width and depth.
Less than 1/8”
These small cracks can be filled with Muscle Fill. Before applying Muscle Fill, make sure the crack is clear of any debris.
Greater than 1/8”
These larger cracks will need to be ground out to ensure a good, long-lasting bond between the patch and the concrete. You can simply use a handheld grinder designed for use in cracks. Don’t worry about opening the crack up further” this is the expected result. You can also use prep solution, such as, Muscle Prep, but we do not recommend this option for the best results. For these cracks, you should use a two-part epoxy system with sand, such as, our product, Muscle Patch. The sand will add strength to the patch and help it last for a long time. All loose debris and material will need to be cleared out of the crack before applying the patch. We also recommend putting applying a primer to the crack before doing the Muscle Patch application. Apply Muscle Patch while the primer is still tacky.
Holes and Chips
Holes and chips can be filled using the same basic guidelines for filling cracks. One important thing to keep in mind though, is that any chips or holes that are very shallow will need to be ground out to create a vertical side for the patch to adhere to.
Lifting can be a serious issue. It can become a tripping hazard or threaten the structural integrity of the concrete floor. Any area that is lifting should be thoroughly examined. It’s best to find the source of the problem and eliminate it! To repair areas that have lifted, we recommend using our product, Extreme Patch. This product is similar to Muscle Patch, but is stronger and allows for better expansion and contraction. You will likely need to grind down the edges of the lifted areas. Resist the temptation to grind it all the way down though! Doing this will significantly weaken the slab. Use Extreme Patch to level out the area. You probably will not be able to get the floor perfectly flat, but you will be able to at least eliminate the tripping hazard.
