Download our Installation instructions.
Can I install a storm door over my Therma-Tru door?
The addition of a storm door will not void the warranty on Therma-Tru entry doors.
What paints can be used on Smooth surface doors without priming?
Smooth surface doors come ready to paint. After cleaning, paint the door using a high quality exterior grade acrylic latex paint. Be watchful of paints with major ingredients like "vinyl polymers" or "polyvinyl acetate" or that are labeled "interior/exterior." In many cases they do not adhere well to Smooth-Star doors.
Which Therma-Tru Benchmark Collection doors can be stained?
Wood-grained doors.
What paint should I use on wood-grained Therma-Tru doors?
These doors should be primed and painted with a high quality acrylic, alkyd or oil-based exterior house paint. Primer and paint should be produced by the same manufacturer and be made to work together. Paint all exposed sides, edges and ends of the door.
Do I have to prime wood-grained doors?
No, it is not necessary to prime the door, but if your door has a lite in it, then the moulding around the glass should be primed with an acrylic primer. Wipe the frame with a clean cloth first, then prime and paint.
