APPLICATION AND USE

Preparation Sandblast or grind to bright metal finish. Remove all blasting/grinding/sanding residues with a clean air line and sweep with a clean brush or broom. (Vacuum clean for best results.) Immediately apply Viny-Lux Primewash 353/354 thinned 25 percent with Viny-Lux Solvent 355.

If small amounts are required, the mixing ratio by volume is 7 parts Viny-Lux Primewash Base 353 to 1 part Viny-Lux Primewash Reducer 354 to 2 parts Viny-Lux Solvent 355. Mix only as much as you can use in the stated pot life.

Some Important Points

Do not apply more than one coat. Do not apply in excess of 0.5 mils DFT. Excess film thickness will lead to delamination and splitting. Be careful not to leave puddles in deep sanding tracks. Do not use a cloth to remove blast residue as the cloth may leave fibers behind which can cause wicking of moisture through the primer system and cause premature failure. Product temperature should be minimum 10 degrees C/50 degrees F and maximum 29 degrees C/85 degrees F. Ambient temperature should be minimum 10 degrees C/50 degrees F and maximum 35 degrees C/95 degrees F. Substrate temperature should be minimum 10 degrees C/50 degrees F and maximum 29 degrees C/85 degrees F.

Compatibility/Substrates

Apply over bare metal only. Metal surface must be thoroughly dry and free of all rust, mill-scale, grease, oil and paint. Sandblasting, power wire brushing and grinding with medium grade (grit) emery cloth are the best methods of cleaning. Do not use coarse sandpaper or grinding wheels.
