Recoat

Eco-PT Topcoat may be used to coat over an existing epoxy in sound condition. Detergent scrub and rinse with clean water to remove surface dirt, grease, oil and contaminants. Floor must be sanded thoroughly with 80 grit paper/60 grit screen prior to recoating. We recommend thorough sanding with a swing-type buffer so that multiple scratch marks cause an obvious gloss loss on all areas (depressions will remain shiny), and the floor is uniformly dulled. The ability to see individual scratch marks is an indication that sanding is not adequate. Scrub with detergent and rinse with clean water before coating.

Sanding Required

Eco-PT Topcoat must be thoroughly sanded if applying Eco-HPS 100 (see chart below). APPROXIMATE SAND TIME (hours) - °F (°C): 65 (18.3) 70 (21.1) 75 (23.9) 80 (26.7) 90 (32.2) 24 20 16 12 8 Eco-PT Topcoat must also be sanded if applying other Tennant urethanes after 24 hours. Use 80 grit sandpaper except for Eco-HPS 100, WearGuard™-240 Gloss and Tennant CRU–use 100 grit sandpaper. The use of more aggressive paper will introduce deep grooves that will not be covered by a single, thin coat of urethane; swirl marks will be particularly evident if the topcoat is glossy. We recommend thorough sanding with a swing-type buffer so that multiple scratch marks cause an obvious gloss loss on all areas (depressions will remain shiny), and the floor is uniformly dulled. The ability to see individual scratch marks is an indication that sanding is not adequate. Scrub with detergent and rinse with clean water before coating and tack rag to remove fine dust.
