Painting & Staining

Immediately following installation, all bare wood windows and doors must have a top quality finish applied to the exterior and interior surfaces. Periodically, wood windows and doors must be refinished, as needed, to avoid damage to wood parts.

GENERAL GUIDELINES

  • Immediately following installation, all bare wood windows and doors must have a top quality finish applied to the exterior and interior surfaces. Periodically refinish as needed to avoid damage to wood parts. It is the homeowner's responsibility to select a high-quality interior or exterior paints and stains, to prime all wood surfaces, and to follow the paint or stain manufacturer’s directions for the proper application of their product. When applying a finish, do not apply paint or stain to weather strip, vinyl, plastic, metal or any other non-wood parts. Solvents in paints, stains and varnishes will cause plastic or vinyl parts, in particular, to become brittle and require replacement. Do not apply a finish to any surface which has an abrasive or sliding contact with another surface. Clean and dry bare wood surfaces before applying your choice of finish. Remove handling marks, debris, or effects of exposure to moisture by sanding lightly with 220 or 320 grit sandpaper. Do not use cleaners containing abrasives or solvents on Marvin products. Clean with mild detergent and warm water. Stain or clear coat finishes are not recommended for exterior wood window and door surfaces.* Do not apply lacquer or varnishes over primed parts.
  • In addition to recommendations found in Marvin Windows and Doors General Painting/Staining instructions, products installed in high humidity and high moisture environments should have a finish applied prior to installation. Finishes used should be appropriate for each area, and be of a grade sufficient to protect the units from moisture damage, providing water shedding properties while allowing water vapor to diffuse to the exterior. Units should be finished with operable sash removed. All accessible wood portions should be finished. High moisture areas include certain regions of Japan, Ireland, the United Kingdom and the United States.
  • Marvin treats exposed millwork on windows and doors with a water repellant wood preservative. If any portion of the millwork is cut off or otherwise disturbed (by installation or damage in the course of the product’s lifetime), untreated wood will be exposed to the elements and may deteriorate. Untreated wood must be protected by a water repellant wood preservative which contains at least 0.5% IPBC. Apply as recommended by the treatment manufacturer. Failure to retreat properly or adequately voids warranty.

* Some exceptions may apply.

PAINTING A WOOD EXTERIOR

A bare wood, brand new Marvin window or door must be painted immediately to prevent possible damage to the wood, even if the window or door is already primed. Primers function to maximize adhesion between the wood and the paint; they do not offer any protective qualities.

  • Make sure all bare wood window and door surfaces are clean and dry. Remove any handling marks, debris or effects of exposure to moisture by sanding lightly with fine sandpaper and wipe clean before applying paint. Before finishing, run a strip of masking tape along the edge of the glass, leaving a 1/16' (1.5mm) space between the tape and the wood. This will allow you to lap the finish coat onto the glass for a proper seal. To make sure you get good paint adhesion, high-quality primer should be used. Apply one coat of primer and two coats of top quality paint according to the paint manufacturer's instructions. Use only a high-quality oil base or latex paint. Paint windows with sash or panels opened (or removed altogether) and do not close (or reinstall) until thoroughly dry. Carefully follow paint instructions, and make sure you wear adequate hand and eye protection.

Windows and doors with a wood exterior should be inspected and repainted periodically. Any signs of blistering, peeling or cracking in the finish should be immediately repaired to protect the wood underneath. Consult with a local paint store or house painting contractor for the best solution for your needs. If you notice any cracks, they should be caulked prior to repainting with a high-quality caulking material or a paintable grade caulking compound.

Paints, stains, and varnishes contain solvents which, when coming in contact with plastics and vinyl used in weather stripping, cause these materials to lose their flexible qualities, making them brittle. Even momentary contact between the finish and the plastic will cause this to occur. Also, do not allow strong detergents, ammonia, solvents, chemicals or other harsh cleaning substances to come in contact with painted exterior surfaces as they can be damaged.

STAINING A WOOD EXTERIOR

FINISHING OR PAINTING A BARE INTERIOR WOOD

If you have a brand new, bare wood Marvin window or door, you must finish it immediately to prevent possible damage to the wood. Even a primed window has no guarantees; primers function to maximize adhesion between the wood and the paint. They do not have any protective qualities.

  • Make sure bare wood window and door surfaces are clean and dry.
  • Remove any handling marks, debris or effects of exposure to moisture by sanding lightly with fine sandpaper and wiping clean before applying your choice of finish.
  • Before finishing, run a strip of masking tape along the edge of the glass.
  • If you are using paint, leave a 1/16" (1.5mm) space between the tape and the wood bead which will allow you to lap the paint onto the glass for a proper seal.
  • Carefully follow paint or stain instructions, and make sure you wear adequate hand and eye protection.
  • Marvin uses a rubber-like material between glass panes and wood sash frames to ensure a weather tight seal. Occasionally, an excess of this silicone sealant, called “squeeze-out,” appears around the edge of the glass. You can safely scrape off “squeeze-out" with a plastic putty knife without damaging the weather tightness of your window or door.
  • Caution: It is extremely important that you do not paint locks, hardware, weather stripping, jamb liners or any surface which comes in contact with another window or door surface.
  • Use paints, stains and varnishes with care-they contain solvents which, when coming in contact with plastics and vinyl weather stripping, cause these materials to lose their flexible qualities.

TREATING EXPOSED PARTS

Marvin treats exposed millwork (wood) on windows and doors with a water repellant wood preservative. If any portion of the millwork is cut off or otherwise disturbed (by installation or damage in the course of the product’s lifetime), untreated wood will be exposed to the elements and may deteriorate. Untreated wood must be protected by a water repellant wood preservative which contains at least 0.5% IPBC. Apply as recommended by the treatment manufacturer. Failure to retreat properly or adequately voids warranty.

PAINTING OVER A CLAD FINISH

Marvin’s clad-wood products feature low-maintenance, extruded aluminum exteriors on both the sash and frame, and a commercial grade paint finish that meets AAMA 2605-05. It's resistant to chalking and erosion, keeping paint looking fresh and vibrant for years.

Painting over Marvin’s factory-applied clad finish voids any warranty, written or implied. Marvin Windows and Doors will not be responsible for any window or door which has had paint applied over its clad finish.

REPAIRING NICKS OR SCRATCHES TO EXTERIOR CLAD FINISHES

Small nicks and scratches to Marvin’s factory-applied exterior clad finishes can be repaired using touch-up paint orderable through your local Marvin retailer.
