PREPARATION
|
| • |
All surfaces should be cleaned before sealing for best penetration and performance. Clean all dust, debris and loose material. Remove oil, grease, algae, grime, mildew or mold with appropriate cleaners.
|
| • |
After cleaning, test absorbency of surface by sprinkling a few drops of water on the surface. If the water does not readily penetrate the surface, stripping will be necessary to remove old coatings prior to applying product. Retest surface after dry. (Sanding or removal of paint containing lead may be hazardous. Call 1-800-424-LEAD for details.)
|
APPLICATION
|
| • |
Do not use if air or surface temperature is below 35°F.
|
| • |
Do not apply in rain or when rain is imminent.
|
| • |
Combine equal parts Seal-Once and clean water (1:1 ratio). Use a paint stick or jiffy mixer and mix for one minute. Do not entrain air while mixing. DO NOT THIN.
|
| • |
Apply one even coat with garden sprayer, brush, roller, air-assisted and/or airless sprayer. Use coarse spray pattern.
|
| • |
For best results, apply in the evening, out of direct sunlight, and at cooler temperatures.
|
| • |
When applying in direct sunlight and wood is hot, spray with a mist of water and apply immediately on dampened surface.
|
| • |
For wood: Apply to all wood surfaces and ends.
|
| • |
Do not use with other waterproofing products.
|
| • |
An additional second or third coat may be needed on dry, porous wood. In high traffic areas on wood, application may be necessary every 2-3 years only in worn areas.
|
| • |
Can be stained or painted after Seal-Once™ is cured. |
| • |
Approximate coverage: 200-300 square feet/gallon. Actual coverage will vary due to porosity of surface.
|
DRYING TIME
|
| • |
Wood surfaces: Allow water to evaporate before subjecting surface to light foot traffic; 24-48 hours for full cure, depending on temperature and humidity.
|
| • |
Concrete/masonry surfaces: Allow surface to dry 1-2 hours depending on temperature and humidity.
|
| • |
When recoating, apply as soon as previous coat has penetrated the surface.
|
CLEAN UP
|
| • |
Clean equipment and brushes with warm, soapy water.
|
| • |
Store unused product above 32°F, protect from freezing.
