This innovative product forms a molecular bridge, chemically fusing the coating with the surface. The product can be used on various surfaces, including concrete, wood, aluminum, etc.<\/p>\n<p>Various surfaces and coatings can be coated with Rockhard Fusion Primer. However, remember that water-based coatings cannot be used over top coats. No surface profiling is required to achieve a strong chemical bond to concrete as long as the substrate is clean and free of bond breakers like oils, greases, etc.<\/p>\n<p><em>*<strong>Gas emissions from this coating system can affect air quality indoors due to its high VOC content, so please take extra precautions when installing it.<\/strong><\/em><\/p>\n<h4>Coverage Rates<\/h4>\n<div class=\"table-wrapper\">\n<table width=\"548\">\n<tbody>\n<tr>\n<td><strong>System<\/strong><\/td>\n<td><strong>Sqft.
