Handling & Finishing

Handling & Finishing

Supa Doors should be handled in the same way you would a good quality lumber door. Here are some basic instructions that may be helpful in handling our product.

1. Doors should not be delivered to a job site or installed until concrete floors, foundations and plaster or drywall are completely dry.

2. Doors should be stored flat on at least three equally spaced 2 X 4’s in a dry, well ventilated area. Do NOT lean up against walls.

See complete handling, finishing and nail filling instructions.

Finishing

1. Doors supplied primed should be well sanded with 150 grit sandpapers, then wiped clean and finished with two coats or good quality oil based or latex paint.

2. To properly seal and finish doors, use a high grade product and apply in strict compliance with the manufacturers specifications.  If you are using latex paint do not over dilute or water down.

3. Door ends must be sealed before hanging.

4. Doors should be finished on all six sides before hanging or immediately thereafter.

5. When finishing doors, finish both sides at the same time, do not leave one side unfinished for a prolonged period of time.  See full finishing, handling and nail hole filling instructions.

Sanding and Prepping for Final Coat

Supa Doors applies 2 coats of water based acrylic primer to every door.

Supa Doors also applies a filler spackle to all nail hole inserts which exist as a result of trim being nailed on, or glazing bead nail on.

This nail hole spackle may not be perfectly filled when the door arrives to you. It is the responsibility of the paint contractor to fill all nail holes prior to applying finish paint coats.

Supa Doors does not warrant that all such nail holes will be perfectly filled and will NOT be responsible for any charges by the painter, contractor or distributor for such nail holes filled.

Supa Doors sands all door edges and sticking as well as bevels on panels. This provides a smooth finish prior to shipping. However, all surfaces including faces, edges, bevels and sticking may require further sanding by the contractor prior to painting final coats depending on your finish required.

Supa Doors does NOT supply a paint ready door.

Priming

Our state of the art, fully automated priming line enables us to supply the most consistent top quality doors, ready primed, almost ready to accept final coats of paint to the color of your choice. All primers are water based acrylic paint.

Important Pre - Drilling & Screw Information

All Supa Doors have wood edges. However, pre-drilling
is an essential part of installing your door:
Since all Supa Doors have wood edges this information is particularly important where there may not be edge in place, i.e. top edges for roller catches OR edge screws for certain mortised lock preps.

1. Screw Type – Preferably single thread parallel core screws are recommended for use with all M.D.F. doors (including wood edge doors).

2. Pre-drilling – It is imperative that you pre-drill pilot holes and do NOT over tighten screws.  M.D.F. is a fiber board and if not pre-drilled the fibers stretch on either side of the screw hole, which is unsightly but does not affect the integrity of the door.  If this splitting occurs fill with vinyl spackle. 
3. The pilot hole should be 90-95% of the screw core diameter.  You should also make sure that the pilot hole is drilled approximately 1/8” deeper than the length of the screw being used.

4. Do not over-tighten screws – set clutch on drill to minimum.  Over-tightening of screws causes a wedge effect and creates minor splits approximately 1/16” on either side of the screw.  If splits appear loosen screw slightly and fill split with vinyl spackle.  The integrity of the door will not be compromised and the full lifetime warranty will stay in place.

5. We recommend #8 x 1-1/4” screws for 1-3/8” doors and #10 or 12 X 12-1/4” screws for 1-3/4” doors.  6’8” doors require 3 hinges and 8 ft. doors 4 hinges.
