DESCRIPTIONKeracaulk™ S (sanded) and Keracaulk U (unsanded) are premium-grade, easy-to use, easy-to-clean siliconised acrylic caulks formulated to match the colour and texture of MAPEI sanded and unsanded grouts.

FEATURES AND BENEFITS• Contain a mildewcide to make both caulks resistant to degradation from

mildew (after cure)

• Paintable

• Water cleanup while fresh

• Packaged in gun-grade tubes for easy application

• VOC-compliant

INDUSTRY STANDARDS AND APPROVALSGREEN STAR™ - Keracaulk™ S (sanded) and Keracaulk U (unsanded) can contribute valuable points towards Green Star™ projects due to the very low VOC content in these products. Refer MSDS Section 9 for further details.

WHERE TO USE• For gaps up to 6mm

• As a flexible barrier/filler between horizontal and vertical surfaces to prevent cracked tiles due to expansion

• For filling joints where tile abuts dissimilar surfaces

• For caulking around sinks, tubs, showers, countertops and ceramic tiled floors

• For interior use only

• For restoring cracked or worn grout joints

LIMITATIONS

• Do not install over substrates containing asbestos.

• Application temperature range is +10°C to +32°C.

• Apply only to clean, dry surfaces.

• For both Keracaulk™ S and Keracaulk U, joints should not exceed 6mm in width.

• Do not use for exterior projects or applications subject to constant water immersion.

• Do not use in areas where joints will be subject to heavy abrasion or wear.

• Allow new concrete to cure for 30 days before caulking.

• Although Keracaulk™ S and Keracaulk U are colour-matched to MAPEI’s grout colour system, expect a slight variation in colour due to the difference in composition between materials.

• For applications beyond 6mm in depth, the caulking depth must be controlled by a closed-cell backer rod.

• Do not use in a thin application.

• May stain porous materials (conduct test on separate area before final application).

SURFACE PREPARATION• Surfaces must be structurally sound, stable, clean and

free from dust, oil, grease, paint, gypsum patch, flooring adhesive, tar, wax, sealers, curing compounds, form release agents, laitance, loose particles and foreign substances that could reduce or impair adhesion.

• Remove all traces of paint, loose particles, residue and cement particles by mechanical means.

• Remove mildew by scrubbing with a mixture of 118ml of trisodium phosphate (TSP), 946 ml of liquid bleach and 2.84L of warm water. Protect eyes and hands by wearing goggles and water/chemical resistant gloves. Thoroughly rinse and allow surface to dry completely before caulking and painting.

• Vacuum out joints and wipe them clean with a damp rag.

Consult MAPEI’s Technical Services Department for installation recommendations regarding substrates and conditions not listed.

PRODUCT APPLICATION1. Read all installation instructions thoroughly before

commencing work.

2. Tiles should be firmly set before caulking. Typically this is 24 to 48 hours after tile installation.

3. Caulking may be done either before or after grouting.

4. For a clean, straight and neat caulk joint, mask both sides of the joint with masking tape.

5. Keracaulk™ S and Keracaulk U come ready to use. Apply with a caulking gun. Do not open cartridges until preparatory work has been completed.

6. Cut nozzle tip to desired bead size at 45-degree angle.

7. Completely fill joints with sealant and smooth over with a wet finger.

8. Excess caulk should be removed with a damp cloth before caulk skins over.

9. Immediately wash hands and tools with warm water and soap.

PROTECTION1. Allow at least 4 to 6 hours drying time before painting.

2. Protect from water exposure until fully cured (at least 72 hours).

Note: Larger beads of caulk and cool, humid conditions will require a longer drying time.
