PRODUCT DESCRIPTION

LATICRETE Latasil sealant is a high performance, one component, neutral cure, 100% silicone sealant designed for ceramic tile & stone applications.

• Exterior and interior use.
• Swimming pools and other wet area applications.
• Joints for ceramic tile & stone applications.
• Expansion joints in residential and commercial applications.

• Conforms to ASTM C-920 and ASTM C-794 adhesion properties.
• Equipped with fungicides to resist mold & mildew growth.
• Resistant to pool chemicals.
• Matches top 19 LATICRETE grout colors and clear.
• Easy to smooth and tool.
• Excellent for masonry construction.
• Excellent movement capacity-25% extension & compression.
• Can be used where ceramic tile abuts glass and window framing.
• Compliments LATAPOXY^® 310 Stone Adhesive system (see section 10. FILINGSYSTEMS).

• Stone
• Glass
• Metal/Steel
• Ceramic Tile
• Masonry Surfaces
• Wood and Plastic Surfaces

Available in 10.3 oz (305 ml) cartridges; 6 tubes per carton.

• LATICRETE^® Latasil^™ 9118 Primer-one pint (.47 l) jar, 5 pints (.47 l) per carton.

• Coverage will vary depending upon joint size and width.
• Approximately 11 lineal feet (3.35 m) per tube at 3/8" by 3/8" (9 mm x 9 mm) joint width.
• Approximately 25 lineal feet (7.62 m) per tube at 1/4" by 1/4" (6 mm x 6 mm) joint width.

When stored in the original, unopened containers at or below 90°F (32°C), LATICRETE 9235 Latasil sealant has a 12 month shelf life.

• Adhesives/mastics, mortars and grouts for ceramic tile, pavers, brick and stone are not replacements for waterproofing membranes. When a waterproofing membrane is required, use a LATICRETE Waterproofing Membrane (see Section 10 FILING SYSTEMS).
• A test area should be conducted when used with stone. Test sealant on small area to verify results.
• Use LATICRETE Latasil 9118 Primer for porous stone and tile and for wet area applications. Conduct a test area to verify results.
• Not for use in applications where physical abuse or abrasion is likely.
• Do not use on or adjacent to building materials that may bleed oils, plasticizers or solvent materials such as impregnated wood, oil based caulks, green or partially vulcanized rubber gaskets or tapes.
• For stone installations, test a small area to check for any fluid migration and to verify results.
• Not a structural glazing adhesive.
• Joint depth should not exceed 1/2" (12 mm) thickness (use backer rod for deeper joints).
• Joint width should not exceed 1" (25 mm) and be narrower than 1/8" (3 mm).
• For perimeter sealing or expansion joint design, the ratio of the joint width to sealant depth should be roughly 2:1.
• Cannot be painted.

Consult MSDS for more safety information.

• Protect finished work from traffic until fully cured, generally 24 hours at 70°F (21°C).
• Sealant must cure a minimum of 14 days at 70°F (21°C) / 50% R.H. prior to exposing to continuous water submersion.
• Maintain surface temperature between 40°F (4°C) and 90°F (32°C) during installation and for 24 hours thereafter.
• Uncured sealant may irritate eyes if contact is made. Avoid contact with sealant until cured.
• Keep out of reach of children.
• If uncured sealant comes in contact with skin, wash with soap and water immediately.
• Always use LATICRETE Latasil with adequate ventilation and avoid prolonged breathing of vapor and prolonged skin contact.

Adhesion performance according to ASTM C-794.
Conforms to ASTM C–920 Sealant classification.

• Clean all joints and surfaces to receive sealant, removing all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants and protective coatings.
• Metal, glass and plastic surfaces should be cleaned by mechanical or solvent procedures. Simple detergent or soap and water treatments are not acceptable. In all cases where utilized, solvents should be wiped on and off with clean, oil and lint free cloths.
• When using any solvent always follow solvent manufacturer's safety, handling and installation recommendations.

Substrates For Priming
Use LATICRETE Latasil 9118 Primer for these substrates:

• Stainless Steel
• Sandstone*
• Metal
• Limestone (or other Porous Stones)
• PVC
• Fiber Reinforced Cement

* Subject to testing and approval by LATICRETE. Actual stone samples to be provided for testing.

• Use LATICRETE Latasil 9118 Primer for all permanent wet area applications.
• For underwater or continuous wet area applications, polyethylene foam backer rod is recommended. Use polyethylene tape on joints too shallow to accommodate foam rod. Polyethylene backer rod is "closed cell" which is water repellent.

• Use polyurethane or polyethylene foam backer rod for deep joints. Use polyethylene tape on joints too shallow to accommodate foam rod. These materials allow the silicone to stretch freely with joint movement.
• Apply masking tape to the face of the veneer. Masking tape will allow for easier removal of sealant if it comes into contact with the face of the veneer. Sealant should only be applied into the joints, adhering to the flanks of the veneer. Applying the masking tape results in a cleaner look, and allows for easy tooling without affecting the face of the veneer.
• Apply sealant into the joint, filling completely.
• Finish joints with a "Jointing Tool" when complete (within 5-7 minutes) for a smooth professional finish.
• Remove masking tape immediately after tooling. Wipe any sealant off the face of the veneer immediately.

Cured joints should be cleaned regularly with a neutral pH cleaner.
