646 PLUS
is new CLASS of semi gloss water based  sealer.

This Self-crosslinking acrylic resin, along with a solvent-free polyurethane, is a one component system.
This sealer performs as well as two part epoxy type products.
646 PLUS outperforms 2 part expoxy products in hot tire resistance tests.

This product has never before seen early water, and stain resistance.
That means it will become imprevious to re-emulsification
in a shorter time than any other sealers.

SATIN 646 PLUS is below 100 V.O.C., meeting SoCal A.Q.M.D. requirements. SATIN 646 PLUS is a water based, breathable sealer that performs better than oil based lacquer.

This product makes oil based lacquer obsolete. You can not use lacquer where vapor pressure, exists, as on patios, driveways or surfaces in contact with the earth. 
Use 646 PLUS in areas where hydrostatic pressure exists. 

646 PLUS meets, or beats the performance of competitive products both in protection and hardness. It is easy to use, without overwhelming, harmful or heavy odors.

DIRECTIONS: Test SATIN 646 PLUS first on an un-installed piece of stone. Apply 646 PLUS with a brush, sprayer, roller, or sponge mop. Work the first coat into tiles for deep penetration. When visibly dry; apply a light second coat. If the surface darkens or appears wet, it is not yet sealed and needs another coat. Tiles are completely sealed when further coating does not darken or give a wet appearance. 
NEVER APPLY ANY SEALER TO A SURFACE UNLESS IT IS COMPLETELY CLEAN AND DRY!

DO NOT LEAVE PUDDLING! Sealer will not dry clear if left to puddle.

COVERAGE: One gallon of MATTE FINISH 646 will cover approximately 200 sq. ft per gallon. That is the total amount of sealer we estimate on an average porosity, to get it completely sealed. Some stones may use more if they are very porous. This is a multiple coat product. Let surface become visibly dry between coats. 
When using as a joint stabilizer; spread sand over the pavers, and squeegee the surface clean. Spray on sealer then again squeegee the surface to avoid puddling, and work into joints. Figure about one gallon per 100 sq. ft. on 12 X 12 pavers. When using on decomposed granite; figure about 30 to 40 sq. ft. per gallon.

LIMITS: Do not use below 60, or in hot mid-day direct sunlight. Do not let 646 puddle or run down vertical surfaces. When testing for desired results be sure to allow 24 hours for curing. Neither 646 Plus or 686 Plus are not for use on ceramic, porcelain, polished marble, travertine or polished granite.

CAUTION: Use rubber gloves when applying. Avoid contact with skin. Prolonged exposure to vapors may be harmful or fatal. Use in a well ventilated area. In conditions which do not permit good ventilation; use of a breathing apparatus is recommended.
