Micro-seal HD Silane Siloxane Water Repellent | Concrete Brick Block Stucco | Clear Non Film Forming

The Coverage Rate depends on the surface. Test the product on a small area of the substrate to estimate coverage. Extremely porous surfaces may require multiple coats.

The use of fluted, scored block, raked joints, sandblasted or etched surfaces will result in a greater absorption and lower coverages rates by up to 40%. Test these areas for the expected coverage rate before general application. Allow for this increased surface area when determining material requirements.

MIXING AND APPLICATION INSTRUCTIONS

Priorto application, all surfaces shall be clean and dry with no oils, dirt, debris or minerals such as efflorescence, lime and calcium. These stains, along with others, will prevent proper penetration of Micro-Seal HD to sufficiently seal for the warranty period.

The use of RainguardPro’s Restore-N-Prep Concrete and Masonry Cleaner system is recommended as a pre-treatment to clean masonry surface. Once clean, allow the surface to fully dry before sealing or applying a topcoat.

WORKING WITH CONCENTRATES

FOLLOW THESE SIMPLE APPLICATION STEPS

1. Apply Micro-Seal HD using a hand pumped garden sprayer (do not atomize) or low-pressure airless spray equipemnt
2. If using airless spray equipment we recommend a spray tip size of .035 to .051. Spray head should be held 8 to 12 inches from the surface.
3. Apply a fog coat quickly followed by a flood coat that runs down the wall approximately 6-12 inches below the point of application
4. Apply material following the coverage rate previously listed (P.1.)
5. Avoid application in windy weather
6. Trigger gun off at the end of each pass to avoid using excessive materials.
7. Multiple coats may be applied. Whitening or yellowing will not occur.

Concrete Curing 

Micro-Seal HD regulates the moisture content of the concrete at the curing stage. It prevents quick water evaporation. This alleviates cracking while the concrete is drying. Micro-Seal HD is also breathable for the escape of moisture over time.

Apply Micro-Seal HD at a rate of 300-400 sq ft/ gallon to “wet” the fresh concrete. This is typically done the day after pouring the concrete and after form release agents, oils and other products are properly prepared to receive a curing aid.

Test Panel 

Always apply Micro-Seal HD onto a mock wall or test panel. Tes the wall or an actual surface area to determine acceptable color, surface porosity , application rates and methods before starting general application.

Safe Handling

Use product only with adequate ventiliation and/or an appropraite cartridge type respirator. Avoid contact with skin and wear protective gloves. Read the Safety Data Sheet before using.

Precautions

Use material in a well-ventilated area. Protect the work of other trades. Protect shrubbery and other plants with drop cloths. Protect automobiles and all other areas not to be coated from overspary. Remove overspray from any windows, automobiles, metal, etc. as soon as possible should it cocur. TO prevent permanent staining, clean spills or leaks in a timely manner.

All surfaces to be coated should be clean of any dirt and grime, efflorescence, lime run, form oils and realse agents, grease, mud, excess mortar, and mold and mildew, etc. ALl cracks should be poitned or caulked. All voids, beeholes, masonry surface defects and openings such as conduits, pipes, drains, door frames, vents, air conditioner openings, electrical openings, control joints or any dissimlar materiasl hsould be rpeaired using urethane or other approved patching.

Do not apply to surfaces if moisture content is greater than 25%

STORAGE
Store materials in a well-protected area between 45° and 90°F. Avoid freezing temperatures, direct sunlight, and moisture. Keep away from heat sources.
