V. WOOD TREATMENT:

Wood is a unique substrate to seal. Like the tree it came from, each board may have a slightly different grain, composition, and appearance than the one beside it. Consequently, its treatment may need special attention. Generally, any wood, new or aged, is going to need thorough cleaning to prepare it for long lasting Lifetime™ Waterproofing Sealant. The only known acceptable method of cleaning is to power wash the wood with hot water (approx. 180°F/82°C) at approximately 2,000 to 2,200 psi, holding the nozzle a minimum of 6 inches (15 cm.) from the surface. Rinse thoroughly.

Let the wood DRY THOROUGHLY before applying Lifetime™!

Drying time may take 3 – 5 days even in fair warm weather and low humidity. The moisture content of the wood and the atmosphere should be equalized before application of Lifetime™. Since moisture swells wood, any drying and drawing will shrink the wood. Therefore, if Lifetime™ is applied prematurely (before the wood is allowed to dry thoroughly), microscopic pores will emerge between the wood and Lifetime™, thus allowing water penetration. As wood ages, shrinking also occurs, although at a much slower pace. Thus, after aging for perhaps one or more years, a second light coat of Lifetime may be necessary. However, be careful not to apply too much, as the surface may become fairly slick for several weeks or longer. (New wood needs to cure 3 – 6 months before being cleaned and sealed).

If a color other than the natural wood aging is desired, apply a mineral spirits (solvent) based stain after the wood has dried, prior to applying Lifetime. Apply the stain according to manufacturer's directions. After stain is thoroughly dry, the wood is now ready for Lifetime™ application.

When applying Lifetime™ by sprayer, use long even strokes with the wood grain, overlapping each pass by moving approximately 4 inches (10 cm.). If puddling occurs, use a broom or similar object to spread the puddles immediately. EXCESSIVE PRODUCT ON HORIZONTAL SURFACES WILL CAUSE THE SURFACE TO BECOME SLICK. ONE THIN COAT IS ALL THAT IS REQUIRED. TWO COATS OR ONE THICK ONE IS NOT NEEDED NOR RECOMMENDED. Use a sprayer tip as recommended by rental store dealer or professional power washer compatible with the equipment being used.

When spraying, ALWAYS USE PROPER MASK for your own protection! Cover any objects in close proximity, i.e. shrubbery, windows, etc., to avoid a rubber film coverage from any over spray or wind drift.

Allow 1 – 2 hours before testing Lifetime™ for walking purposes. The wood is now ready to begin protecting from water penetration, although hopefully it can stay dry a couple of days before being tested by rain. Periodic cold water power washings, (max. 1,800 psi) perhaps every year or so, will remove surface grime, mildew, etc., and refresh the appearance to a newer look. Cold water power washing will not break down silicone rubber sealant. (See Application Guidelines for additional information.)

VI. CONCRETE TREATMENT:up.gif

New concrete should cure approximately two weeks before applying Lifetime™. If a curing agent other than water was used, i.e. paraffin or other chemicals, the concrete must first be power washed prior to applying Lifetime. Wash with hot water (approx. 180°F/82°C) using degreasing detergent at approximately 2,000 to 2,200 psi, holding the nozzle a minimum of 6 inches (15 cm.) from the surface. Rinse thoroughly.

Let the concrete DRY THOROUGHLY before applying Lifetime™!

Drying time may take 3 – 5 days even in fair warm weather and low humidity. Lifetime™ can be applied to new concrete, cured with water and kept free of traffic to the first two weeks, with no power washing. However, make sure the concrete is thoroughly dry and clean before beginning application. Any used concrete must be power washed, using detergent and hot water, to remove dirt particles, grease, etc. in order for Lifetime to properly penetrate. Periodic cold water detergent power washes using maximum 1,800 psi pressure will refresh concrete, remove any grease and oil accumulated, and provide a newer look.

When applying Lifetime™ by sprayer, use long even strokes with the wood grain, overlapping each pass by moving approximately 4 inches (10 cm.). If puddling occurs, use a broom or similar object to spread the puddles immediately. EXCESSIVE PRODUCT ON HORIZONTAL SURFACES WILL CAUSE THE SURFACE TO BECOME SLICK. ONE THIN COAT IS ALL THAT IS REQUIRED. TWO COATS OR ONE THICK ONE IS NOT NEEDED NOR RECOMMENDED. Use a sprayer tip as recommended by rental store dealer or professional power washer compatible with the equipment being used.

When spraying, ALWAYS USE PROPER MASK for your own protection! Cover any objects in close proximity, i.e. shrubbery, windows, etc., to avoid a rubber film coverage from any over spray or wind drift.

Also, be aware that concrete continues its curing cycle for many years. Therefore, like wood, it will shrink and draw with the passage of time. As this occurs, it may begin to accept some water penetration. If water penetration occurs, first clean the concrete with cold water detergent power washing, allowing ample days to dry. Then apply a second light coat of Lifetime™, and the concrete will again be protected from water penetration for several years. (See Application Guidelines for additional information.)
