Removing old sealer is an important step when resealing stone surfaces to ensure proper adhesion and an even finish. Here's a detailed guide to help you do it effectively:
1. Assess the Existing Sealer
-
Perform a Sealer Test:
- Apply a few drops of water on the stone. If it beads up and doesn’t absorb, the sealer is still intact.
- If the stone darkens quickly, much of the sealer has already worn off.
2. Choose the Right Stripper
- Use a stone-safe sealer stripper specifically formulated for your type of stone and sealer (e.g., penetrating or topical).
- Avoid harsh chemicals like acids, which can damage natural stone.
3. Gather Necessary Tools
- Stripping solution.
- Scrub brushes or pads (non-abrasive for delicate stones).
- Microfiber cloths or rags.
- Protective gear (gloves, goggles, and masks).
- Plastic sheeting to protect surrounding areas.
4. Prepare the Surface
- Clean the stone with a pH-neutral cleaner to remove surface dirt and grease.
- Allow the surface to dry completely before applying the stripper.
5. Apply the Stripper
- Follow the manufacturer’s instructions for dilution and application.
- Apply the stripper evenly with a sponge or brush, ensuring full coverage.
- Let the product sit on the surface for the recommended dwell time (usually 15-30 minutes).
6. Remove the Old Sealer
- Use a non-abrasive scrub pad or brush to agitate the surface gently, loosening the old sealer.
- Wipe away residue with a microfiber cloth or mop.
- Rinse the surface thoroughly with clean water to remove all traces of the stripper.
7. Repeat If Necessary
- For stubborn areas, reapply the stripper and repeat the process until all sealer is removed.
8. Allow the Stone to Dry
- Let the stone dry completely, typically for 24-48 hours, before applying the new sealer.
9. Apply the New Sealer
- Once the surface is dry and free of residue, proceed with reapplying the new sealer following proper techniques.
Tips for Success
- Test in a Small Area: Always start in an inconspicuous spot to ensure the stripper is safe for your stone.
- Work in Sections: For large areas, strip and rinse in smaller sections to prevent drying.
- Use High-Quality Products: Opt for trusted brands to ensure effectiveness and safety for your stone.
