| Surface Preparation | All receiving surfaces must be structurally sound, clean, free of dust, dirt, silicones, paint products, efflorescence or any other contaminant which could prevent proper penetration. Allow new cement and masonry surfaces to fully cure (approximately 28 days) prior to application. A sample area should be tested to be sure no color variation will occur. | |||||||||||||||||||||||
| Application | For best results, use suitable spray equipment, maintaining consistent spray pressure. Starting at the bottom, apply a fog coat followed immediately by a saturation coat. Do not skimp. Porous surfaces may require two coats. Protect all glass and metal surfaces from direct contact or overspray. | |||||||||||||||||||||||
| Clean Up | Clean all tools and equipment with detergent and water immediately after use. Clean up drips, runs, and overspray on non-treated surfaces while MerSeal II is still wet, using detergent and water if necessary. | |||||||||||||||||||||||
