Owatrol Prepdeck – 3in1 Stripper, Cleaner, Millglaze Remover

Owatrol Prepdeck – 3-in-1 Stripper, Cleaner and Mill Glaze Remover is a multifunctional, water-based professional product designed for exterior wood. It removes existing coatings such as stains and acrylic paints, effectively eliminates mill glaze on new timber, and restores the surface by stripping dirt and stubborn contamination. Used undiluted, PREPDECK opens the pores of hardwoods to improve penetration of finishing products. When diluted with water, it becomes a powerful cleaning agent suitable for facades, terraces and garden furniture.
