Sponge or wipe dust/dirt off tile faces and remove water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured Ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Pour SPECTRALOCK PRO Premium Grout Part A Liquid into a clean mixing pail. Then pour SPECTRALOCK PRO Premium Grout Part B Liquid into same mixing pail. Mix by hand or with less than 300 rpm mixer until liquids are well blended. While mixing, add SPECTRALOCK Grout Part C Powder. Blend until uniform. For narrow joints, it is acceptable to leave out up to 10 percent of SPECTRALOCK Grout Part C Powder to produce a more fluid mix. Install grout in compliance with current revisions of ANSI A108.02 (3.13) and ANSI A108.6 (3.0 to 4.0). Spread using a sharp edged, firm rubber float and work grout into joints. Using strokes diagonal (at 45 degrees angle) to grout lines, pack joints full, free of voids/pits. Holding float face at 90 degree angle to grouted surface use float edge to "squeegee" off excess grout, stroking diagonally. Once removed, a thin film/haze will be left. Initial cleaning of film/haze can begin 20 minutes after grouting (wait longer when temperatures are cooler). Mixing one cleaning additive packet with 2 gallons (7.6 L) of clean water in clean bucket. Dip clean sponge into bucket wring out cleaning solution until sponge is damp. Using circular motion, lightly scrub grouted surfaces with damp sponge to loosen film/haze. Drag sponge diagonally over scrubbed surfaces to remove froth. Rinse sponge frequently. Change cleaning solution every 50 sq ft (4.7 sq m). Check work as you clean. Repair any low spots with additional grout. 1 hour after finishing first cleaning, clean area again following same procedure but use a clean white scrub pad and fresh cleaning solution. Rinse scrub pad frequently. Drag a clean sponge diagonally over scrubbed surfaces to remove. Use each side of sponge only once before rinsing. Change cleaning solution 50 sq ft (4.7 sq m). Allow cleaned areas to dry and inspect surface. For persistent grout film/haze (within 24 hours), repeat procedure with undiluted white vinegar and clean pad. Rinse with clean water and allow surface to dry. Inspect grout joint for pinholes/voids and repair with freshly mixed grout. Do not use undiluted white vinegar on polished marble or limestone unless a test spot indicates no change in finish appearance. Do not use acid cleaners on epoxy grout less than 7 days old. | |||||||||||||||||||||||||||||||||||||||||||||||||

Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Pour SPECTRALOCK 2000 IG Part A and Part B into a clean mixing pail and mix thoroughly with drill mixer until liquids are completely blended. Add the SPECTRALOCK Part C powder. Mix thoroughly with a high speed mixer ( greater than 450 rpm) for a minimum 2 minutes and until uniformly blended. This aerates grout to a fluffy mix. Grout may remain in bucket while grouting. Spread using a sharp edged, hard rubber float and work grout into joints. Using diagonal 45 degree angle strokes to grout lines, pack joints full and free of voids. Hold float face at 90 degree angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to reduce pulling grout out of filled joints. Initial cleaning can begin 15 minutes at 70 degrees F (21 degrees C) after grouting. Add wash cleaning additive to 2 gallons (7.6 L) of clean water and mix until fully dissolved. Do not mix cleaning additive to grout mix. Using a circular motion, lightly scrub grout joints and entire tile surface with a white nylon pad and plenty of water/cleaning additive solution to loosen residue and form joints. Drag a clean damp sponge or damp white terry cloth towel diagonally over scrubbed tile surface to remove froth and grout residue. Rinse sponge frequently and change rinse water often Wait 90 minutes at 70 degrees F (21 degrees C) before commencing final wash. Add Final Wash cleaning additive to 2 gallons (7.6 L) of clean water and mix until fully dissolved. Use same cleaning method as first wash but try to avoid contacting grout surface; clean tile only to loosen any remaining grout haze. Inspect joint for pinholes/voids and repair them with freshly mixed grout. After 12 hours, check for remaining haze and remove it by scrubbing with warm soapy water. Do not use acid cleaners on epoxy grout less than 7 days old. | |||||||||||||||||||||||||||||||||||||||||||||||||
