Guidelines for Treating Your New Shed

(All sheds are to be sealed or treated within 60 days)

All wood sided sheds are sold unfinished and, must be caulked prior to treatment, with a stainable/paintable caulk at any seam that may allow water in, such as trim over the doors, windows, vents and along the tops and sides of all corner boards. Galvanized nails will bleed a darkish stain on wood sheds. To prevent knots from bleeding through your finish, see your paint supply store for a knot sealer such as Binz or Kilz which is available in clear or white and can be applied over the knots before priming/painting or staining.

Cedar sheds must be treated outside within 60 days of installation. We recommend using a high quality penetrating oil stain on the outside. (Avoid water-cleanup and solid stains) An exterior varnish may be used on the interior walls, but this process is only for cosmetic purposes. Cedar is porous and contains tannins, which can cause “water stains” to appear on the inside as humidity leaches the tannins to the surface. They are harmless, but staining or varnishing the inside will minimize this condition.

Pine sheds and pine trim must be stained or primed and painted on the outside within 60 days of installation. Treat the knots, prime all surfaces and use exterior acrylic latex paint for best results.

Smart Panel Sheds are pre-primed but must still be painted (not stained) within 60 days on the outside with an exterior acrylic latex base paint, do not use any oil based product. The outside trim is untreated pine and also needs to be treated in the manner of unfinished wood described above for pine sheds.

All Screen Houses must be treated according to the guidelines above, inside and out. Pressure Treated wood and plywood can and should be treated, after it has dried out for several weeks.

Vinyl Sheds do not require treatment, but may need to be maintained with a vinyl siding cleaner as needed.

NOTE: ALL door types and windows, (with the exception of vinyl), should be painted/stained on all six sides (inside, outside and all four edges) applying extra to the cut edges. This minimizes shrinking and swelling due to weather conditions. It is normal for the doors to shrink and swell; sealing them minimizes any movement. ALL shutters and flower boxes, (with the exception of vinyl), must be removed and sealed on all sides as well as treating the siding behind them.

FLOORS: Use Acrylic Latex Floor paint or Deck Enamel only. DO NOT use Thompson’s water seal or any oil-based product.

These are guidelines only!! Please check with a professional paint supplier for recommendations of painting or staining materials and for proper coverage. Never apply treatment to moist wood. Be cautious of “all-in-one” waterproofing products and water-based stains, though they may preserve the wood, they allow weathering.

RE-APPLY ACCORDING TO MANUFACTURER’S RECOMMENDATIONS. Stains need to be applied more frequently than exterior latex, usually yearly, for best results.

DOOR MAINTENANCE: Due to variations in the weather or slight settling of your shed, the door handle may require periodic adjustment. This is a simple procedure which can be completed in just a couple of minutes using a Phillips screwdriver. Remove the two screws holding the door block and move it so that the latch bar is centered in the loop, then re-install screws. Leave a minimum of ¼” gap between the doors to allow for expansion.
