UNISEAL will effectively solidify punky or chalky concrete or masonry surfaces when used as a primer prior to topcoating. It is also designed to be used on its own as a transparent sealer over interior concrete floors to provide dustproofing and enhanced cleanability characteristics. UNISEAL will amber slightly when used on exterior surfaces without a topcoat.
2. NON DUSTING: UNISEAL penetrates deeply to eliminate concrete dusting, providing for easy cleanup and minimum maintenance.
3. DEEP PENETRATION: Its low viscosity allows UNISEAL to penetrate into and preserve dense surfaces such as smooth-troweled concrete floors and asphalt surfaces.
4. ANTI-SPALLING: Applied to concrete decks, walkways, industrial areas, etc., UNISEAL will effectively protect against the intrusion of destructive salts, oils, solvents and gasoline. It also prevents spalling and pitting caused by freeze/thaw cycling.
PACKAGING AND MIXING
UNISEAL may be reduced with water for increased penetration over dense substrates. Shelf life in unopened containers is one year. Store at temperatures between 50°F and 100°F (10°C to 38°C). Do not open containers until ready to use the material.
Prior to applying UNISEAL, all loose material, dirt and dust shall be removed by use of a power vacuum, stiff bristled broom or compressed air. If concrete is badly spalled, restore aggregate to a reasonable condition using a cementitious patching or resurfacing compound. Previously painted surfaces should be brush blasted or mechanically abraded to remove the existing finish.
New concrete which has been previously cured with a curing compound or new concrete that has been smooth troweled, shall be cleaned and etched with 10% Muriatic Acid solution. Wash with TSP and follow with a rinse of clean water.
Existing concrete shall be cleaned using TSP and water. Cleaning shall be accomplished using mechanical scrubbers. Rinse thoroughly with fresh water to remove all traces of the chemical cleaner. If general cleaning is not adequate, then surfaces should be cleaned and etched as recommended for new concrete.
Allow new asphalt surfaces to cure for a minimum of 60 days prior to application. Clean the surface completely with a commercial grade detergent and rinse thoroughly with plenty of clean water.
If surfaces are highly contaminated, or if surfaces are to be subjected to unusual service conditions, consult our Technical Service Department for recommendations.
Coverage rate will vary depending upon surface porosity. One coat is usually sufficient for sealing substrates when UNISEAL is used as a primer. When used as a sealer/finish, two coats are required to achieve a uniform sheen. Two coats will also be required when sealing lightweight concrete or other highly porous surfaces. The following are approximate application rates:
Thin as necessary with water to achieve adequate penetration of the surface being sealed. When used as a sealer/finish apply a second coat of UNISEAL at approximately 50% greater coverage rate than those listed above. When used as a primer on exterior applications, UNISEAL should be topcoated within 48 hours to ensure optimum bonding characteristics. On interior applications, the dry time is dependant on the ability of the water to evaporate from the film. Use fans to generate maximum air movement.
Use TSP and water to thoroughly flush equipment. Purge the water from the system using mineral spirits. Leave the solvent in the lines and equipment until next use.
LIMITATIONS & PRECAUTIONS
UNISEAL will freeze and become unusable below 32°F (0°C). Do not ship or store unless protection from freezing is available. Do not apply if conditions will not permit complete cure before rain, dew or freezing temperatures occur. Do not apply in the late afternoon if moisture condensation can appear during the night. Do not apply UNISEAL at temperatures below 50°F (10°C), or when there is a possibility of temperatures falling below 32°F (0°C) within a 2 hour period after application.
UNISEAL may be an irritant to skin. Avoid breathing of vapor or spray mist. Approved MSHA/NIOSH chemical cartridge respirator must be worn by applicator. Avoid contact with eyes and skin.
