Coverage
  • For very porous surfaces: 1st coat: 75-150 sq. ft./gallon. 2nd coat 150-300 sq. ft./gallon.
  • For average density surfaces: 1st coat: 200-300 sq. ft./gallon. 2nd coat 400+ sq. ft./gallon
  • Generally, the sealer will go twice as far on the 2nd coat as it did on the 1st coat.
  • Wait 6-12 hours between coats to ensure the previous one is completely dry.
Surface Preparation

Always be sure surface is clean, dry, and free from any dirt, grease, oil, wax, or other contaminant. Read the entire label before using. Use only as directed. Always test on a small piece of material or a small inconspicuous area to determine suitability. Ensure the area is well ventilated. Ideal surface temperature should be between 60°F and 80°F. Product works best when it is the first substance applied to the surface, insuring proper penetration.

Applications

SEALER 444 may be applied with spray applicator, brush, roller, or lint free rag. Apply the first coat liberally to ensure proper penetration, bonding, and to provide a good base. Avoid puddles by wiping up excess.

  • For Sealing Grout Joints: Apply to joint with small brush or squeeze bottle. Allow to soak 10-15 mins. Wipe off excess from tile surface. Do not leave voids and puddles.
  • Smooth Surfaces: apply 444 with a lint free cloth, spray applicator or short nap roller.
  • Rough Surfaces: apply with a ½ to ¾ inch nap paint roller or paint brush.
