An easier to use version of the now discontinued U-2555 primer.
U-4749 Primer is mixed 1:1 with U-4748 catalyst and pre-reacted for 30 minutes before thinning and application.
Reduce up to 40 percent with U-1289, depending on desired film thickness, coverage, and local VOC limits.
Reduction up to 12 percent, or about 15 oz per mixed gallon, allows compliance with the most-stringent air pollution rules for a high build primer.
If rolled, use 1/8" foam roller sleeve and apply 2-3 coats, allowing tack-free time in between. When final coat has solidified but not completely cured, apply first coat of anti-foulant
• Ideal for gel-coat blister repair or prevention
• U-4749 may be used as a barrier coat over gel-coat below the waterline
• Caution - surfaces primed with these primers must be topcoated within 24 hours after sanding. This is important, as exposure to the elements for extended periods before topcoating could result in topcoat-to-primer adhesion failure
• Note — ALL Sterling paint products and components are sold separately
