Thinning: May be thinned up to 5% with POR-15 Solvent. Thinning is not usually required. Subsequent coats may be applied at 12 hour intervals if desired. Stir Tie-Coat thoroughly before using; do not shake as this will create air bubbles. 

Pressure: Spray at approximately 35 lbs. Do not sand between coats of primer. Sand only after final coat of primer has fully dried (24 hours). 

Topcoating: Allow a minimum of 24 hours before applying any topcoat over Tie-Coat Primer. Failure to allow enough dry time before applying topcoats may result in spidering or crinkling of the finish. 

Storage & Handling: Store in tightly closed container and protect from moisture and foreign materials. Ideal storage temperature range is 50 - 81° F (10 - 27° C). 

Summary:

1. Stir, do not shake, Tie-Coat Primer before using.
2. Do not sand between coats. Sand only after final coat has dried thoroughly (24 hours).
3. As with all solvent-based coatings, use an organic vapor particulate respirator, NIOSH/MSHA approved, when spraying or brushing. In closed areas, use an air-supplied respirator when spraying.
