Ninety-Day Primer Gives Extra Protection to Field Exposure

Endura Products of Greensboro, N.C., has announced that its standard 30-day primer will be upgraded to a 90-day primer and will be applied to all FrameSaver® No Rot Exterior Door Frames as well as to all standard door frame components.

The company says while primers are designed to protect against weather elements and to improve the adherence of finish coats and typically have a 30-day protection, field-testing of several primers in real weather conditions resulted in variances of performance. It says the 30-day primer test subjects showed a 30-percent loss of top coat adhesion, while its new 90-day primer showed less than 10-percent loss after outdoor testing.

The company says some of the most frequent causes for field applied paint failures include: field exposure duration beyond the primer's capability, wood that's not fully dry when top coated, and topcoats applied outside of recommended temperature ranges and while a good performance primer offers extra protection against the first cause, it will not resolve the paint failures that result from the second and third causes.

The new primer Endura has identified will standardize the quality of the primer in both FrameSaver's Texas plant and Endura's North Carolina plants. The company says its new primer is already being used in its Texas plant and North Carolina plants will begin using it in November.
