1. Surface Preparation:
- Thoroughly clean the tile countertops to remove any dirt, grease, or debris.
- Allow the tiles to dry completely.
- Apply a chemical degreaser to the tile surfaces and scrub with a nonabrasive pad to remove any stubborn stains or grease.
- Rinse the tiles and let them dry again.
2. Leveling:
- Use a self-leveling compound to address any unevenness in the tile surface. Follow the product instructions to mix and spread the leveling compound.
- Let it dry completely according to the manufacturer's recommendations.
- Sand the leveled surface smooth using fine-grit sandpaper.
3. Primer Application:
- Apply a bonding or adhesion promoter specifically made for quartz countertops over tiles.
- Roll or brush the primer evenly onto the entire surface.
- Follow the product instructions regarding drying time.
4. Cutting Thin Quartz:
- Measure the countertop area and cut the thin quartz sheets to fit. Thin quartz comes in various thicknesses, so choose one suitable for your project.
- Use a diamond saw or a wet tile saw for precise and clean cuts.
5. Apply Thin-set Mortar:
- Spread thin-set mortar onto the prepared tile countertop using a notched trowel.
- Make sure the entire surface is evenly covered to ensure proper adhesion.
6. Install Quartz Sheets:
- Carefully place the cut quartz sheets onto the mortar bed.
- Gently press them down to secure them in place.
- Use shims or spacers to maintain consistent gaps between the sheets for grout lines.
7. Apply Caulk:
- Caulk the countertop seams and edges using color-matched silicone caulk.
- Wipe off excess caulk and smoothen the sealant with a damp cloth or finger.
8. Allow to Set and Cure
- Allow the thin-set mortar and caulk to set and cure according to the product specifications. This can take several hours or overnight.
9. Clean and Maintain:
- Once fully cured, clean the thin quartz countertops with a mild detergent and warm water.
- Dry the surface with a soft cloth.
- Follow regular maintenance instructions for quartz countertops.
Remember, working with power tools and sharp materials can be hazardous, so take appropriate safety precautions and follow manufacturer guidelines for the adhesive, primers, and thin quartz. If unsure about any steps, it's best to consult with professionals or contractors experienced in countertop installations.
