SMOOTH-STAR® UNITS
Painting Door Interior:
1. Clean first with mild detergent and water or use a TSP (tri-sodium phosphate) solution.
Rinse well and allow to dry completely.
2. Mask glass and hardware.
3. Use high-quality acrylic latex house paint, following manufacturer's application instructions.
4. Paint edges and exposed ends of door.

5. Paint edges and exposed ends of door.
Staining Door Interior:
We only recommend the use of the stain and clear coat products found in the Therma-Tru
Finishing System. (See the Therma-Tru Finishing System instructions for complete details.)
1. Clean first with a clean cloth and mineral spirits and allow to air dry OR wash door with a mild
detergent and water, or a TSP (tri-sodium phosphate) solution. Rinse well and allow to dry
completely.
2. Mask glass and hardware.
3. Apply stain with a cloth in a circular motion to one section at a time.
4. Wait 5-10 minutes before brushing, depending on the desire for a lighter or darker shade.
5. Brush with the natural bristle brush in the direction of the grain to “feather” or blend the stain to
a rich wood look. Clean brush tips frequently with a dry cloth to remove excess stain. Stain
and brush out each section completely before moving onto next section.
6. Allow a minimum of 48 hours drying time for the stain to cure before applying topcoat.
REPAINTING PROCEDURE
1. Sand the surface to be re-coated with 180 grit sandpaper to abrade and make porous.
2. Remove all sanding dust from the surface. This can be accomplished by using a damp cloth.
3. Optional: Wipe the surface with a solvent paint deglosser applied with a clean cloth followed
by a final wipe with an additional clean cloth to ensure the surface is free of any contaminates.
4. Apply Sherwin Williams DTM TM Bonding Primer part # B66A50 to the surface and let the
coating dry, following the directions provided on the label located on the back of the can.
5. Topcoat the Sherwin Williams DTM TM Bonding Primer with a high quality acrylic latex

WEATHERPROOF, FINISH AND MAINTAIN
• Add insulation to air space between opening and unit.
• Caulk around entire perimeter of unit on exterior side; seal sealing fins to siding
or facing, seal front bottom edge of sill, seal all joints between jamb and mouldings.
• Seal joints between exterior hardware trim and door face to prevent air and water
infiltration.
• Paint or stain according to Therma-Tru instructions. Do not paint gaskets or
weatherstrip.
• Maintain or replace sealants and finishes as soon as any deterioration is evident.
For semi-gloss or glossy paints or clear coats, do this when surface becomes dull
or rough. More severe exposures require more frequent maintenance.
• All Therma-Tru doors must be finished and maintained in accordance with our
recommendations. Failure to do so may affect the applicable warranty.
• Remove sill tape and labels on glass.
• Use touch-up paint to paint heads of rough opening screws
JAMB EXTENSION INFORMATION
The following images are intended to help clarify how a patio door is
installed in different frame openings.
The jamb extensions are made of standard wood trim materials, readily
available from lumber yards and building material retail stores.

INTERIOR CASING ATTACHMENT
Interior casing may be attached to the frame in either of the following ways:
An air nailer can be used to fasten the interior casing to the frame using 0.050" x
1-½" wire brad nails through the casing and fiberglass frame. For maximum
holding power, ensure that nails are installed through anchor blocks located within
frame profiles. Locations are shown below for standard two-panel systems.
For manual application, we suggest using 4d-1-½" finish nails. They can be used
to secure interior casing to the frame. Pre-drilled pilot holes (1/16" dia.) are
recommended to avoid splitting casing or frame. Ensure that nails are installed
through anchor blocks for maximum holding power.
