Surfaces must be clean, dry and free from all defective and poorly adhering material, dirt, grease and salts and if necessary, they should be thoroughly rubbed down using a suitable abrasive paper. Dry sanding, flame cutting and/or welding of the dry paint film will give rise to dust and/or hazardous
fumes. Wet sanding/flatting should be used wherever possible. If exposure cannot be avoided by the provision of local exhaust ventilation, suitable respiratory protective equipment should be used. Wooden surfaces should be properly leveled with Vivechrom’s ACRYLIC MASONRY PUTTY.
