Applying Deck Stain or Clear Sealer

Before proceeding, make sure the surface is thoroughly cleaned and dry.

Application Guidelines:

If you are going to apply a tinted stain or sealer, mix all cans together to insure uniform color, (referred to as "boxing"). Even If you are using a standard factory mixed color you should not eliminate this step. You need to be assured that you are starting out with the same color and even factory mixed colors can vary from batch to batch. Take an empty 5 gallon pail and add up to 4 gallons of stain, mix thoroughly using a mixing paddle. Pour out a small amount into a 1 or 2 gallon pail for your brush work and use the 5 gallon pail for your roller or paint pad. Routinely stir during application. When you get down to the 2 gallon level add another gallon if you are using a large amount for the total job. By adding new material at intervals like this color uniformity is assured even if there is a difference in color between the cans of material.

Wear Proper Clothes: To protect against skin irritation, a long-sleeved shirt, long pants and goggles. Also use an OSHA approved mask to protect against inhalation of vapors if using solvent based products. For your information and safety, always take the time to read the product labels carefully before use. Before applying stain, test on a sample piece of wood from your deck or in an out of the way place, to verify the color and look you want.

Method of Application:

The preferred application methods are:
  • A quality paint brush, an airless sprayer, a pump-type garden sprayer, paint pad or a short nap roller, 1/4"- 3/8".
  • Apply liberally to dry wood to the point of saturation, allow to sit for 5 minutes or so and remove any puddles with a dry 1/2" roller or paint pad attached to a pole.

The stain should saturate all checks or splits. All exposed ends should be coated several times until all wood pores are saturated. A second coat of stain may be necessary to produce a uniform even finish.

Sealer and Finish:

Stains are designed to color wood surfaces but they need to be protected. As we mentioned in the Introduction, penetrating finishes are superior to coatings such as varnish or polyurethane, because they do not crack, peel, or become opaque. Super Seal is an excellent finish for stained or natural wood surfaces. 100% acrylic water repellent, sealer formulated to provide superior protection from moisture penetration and the effects of weathering. Super Seal is non-toxic to humans, animals, and vegetation. It contains UV filters, and is mildew resistant. Hy-Tech Insulating Ceramics can be added to any sealer to help reduce surface temperatures of wood decks and provide a Non-Skid surface.

Care and Maintenance:

Wood surfaces may need to be retreated every 3 - 4 years or earlier depending on weather exposure. A close inspection of treated surfaces should be done annually.
