Recatable with itself after full drying cycle, sanding becmes necessary if there are defects r after 24 hurs. Plishability Material usage Dust and minr damage can be plished ut after the stated air-dry times have been reached, r after a full bake at 140 F (60 C) bject temperature, fllwed by a cl dwn f the bject t ambient temperature. Carefully sand ut dust particles and restre the surface accrding t the plishing recmmendatins. Ready t plish apprximately 30 minutes after cl dwn t ambient temperature. Carefully sand ut dust particles with #1500 then #2000 grit paper wet paper then plish with apprpriate cmpund. With recmmended applicatin, the theretical material usage is ± 26 sq.ft./liter (8 m²/liter) per cat. The practical material usage depends n many factrs i.e. shape f the bject, rughness f the surface, applicatin techniques, pressure, methd and applicatin circumstances. 4 / 5
