Surface Preparation Before Applying Coatings | Concrete

By far, concrete surface preparation is the most common before applying coatings. 99% of all concrete projects have a very thin film curing agent applied to it. This helps the concrete dry without cracking when initially poured, but is an enemy to epoxy coatings. Therefore, this thin layer of silicone-based compound needs to be completely removed.
