Purpose: WB Gray DTM Primer-Surfacer X3247 is a VOC compliant primer (< 1.0 Lbs per gal.) in a single package. Reduce with water and use this product for degreased bare metal applications where pretreatment is not an option. This medium gray primer builds film quickly, hides minor surface defects, and provides a sag-free groundcoat that can be sanded for smooth finish applications. Recoat with solvent or waterbase topcoats. WB Gray DTM Primer-Surfacer X3247 can replace most 2k solvent base primer-surfacer products in most conventional OEM applications.

Recommended substrates: clean aluminum (smooth, mill finish, gold and clear chromate) ; clean steel (smooth, matte finish, gold and bright zinc plate)

Mix Ratio: reduce as needed, up to 10% parts by volume with tap water.

use of Zahn cups is not recommended

Start with 12 parts primer to 1 part tap water or ~ 9 oz (fl) per gallon

Always Mix well before use

Application: Use conventional air pressurized, suction feed, or HVLP spray equipment. Stainless steel is recommended for all waterbase applications. Fluid pressure and air pressure will vary according to nozzle combination and equipment; note recommended nozzle size 0.055" ‚ 0.070"

Conventional wet films are 6.0 - 8.0 mils.

Reduced 12:1, a wet film of 6.0 ‚ 8.0 mils will yield between 2.2 ‚ 3.0 mils DFT.

primer will not sag or run at higher wet film thickness.

Sanding and Recoat Schedule (will vary with DFT and shop conditions):

ambient room temperature: 2 ‚ 3 hours

Flash-off: 30 minutes @ RT and Force Dry 30 minutes @ 135 -150 F

Coverage @ 12:1 reduction

… 250 sq. feet per gal (coating) per 2.5 mils DFT @ 100% transfer efficiency

Clean up

Water when wet
