Failed Sealer - Granite

Removing Failed or Wrong Sealer from Granite Surfaces

Removing a failed sealer from granite takes time, effort, and care. If unsure or lacking tools, hire a PureSeal approved expert. Sealing outdoor granite patios, paths, or steps protects the stone and enhances its natural look. But wrong sealers cause issues.

Using the wrong sealer or applying it badly can cause peeling, discolouration, patchy spots, or cloudy surfaces. This harms granite’s appearance and lifespan.

The good news: you can remove bad sealers carefully to avoid damaging the stone’s surface.

Why Sealers Fail on Granite

• Granite is dense but porous. Not every sealer fits granite well. Common reasons for sealer failure include:
• Using sealers not made for granite, like surface films instead of penetrating types, leads to peeling or hazing.
• Sealing in wet, cold, or humid weather traps moisture, causing cloudy “blooming.”
• Applying too much sealer or many coats too fast creates sticky, uneven layers that attract dirt.
• Skipping proper cleaning before sealing leaves dirt or residue, causing patchy or peeling results.

How to Remove Failed Sealer Correctly

You must remove the old sealer fully before applying a new, suitable one. This ensures a clean surface and good seal.

Use a Specialist Granite Sealer Remover

Granite needs a professional remover made for natural stone. The right remover will:

✔ Break down failed sealer without harming granite’s finish.
✔ Lift discolouration, bloom, or flaky residue.
✔ Prepare the surface for a fresh, lasting seal.

Avoid generic paint or varnish strippers. They often damage or dull granite permanently.

Best Steps After Removing Sealer

After removing old sealer:

✅ Let the granite dry completely, avoiding trapped moisture.
✅ Choose a granite-compatible sealer, preferably penetrating and non-film-forming.
✅ Apply the sealer in dry, mild weather—no rain or extreme temperatures.
✅ Use thin, even coats to avoid uneven or sticky patches.

Why Use Specialist Removers?

General cleaners or solvents can:

❌ Dull the natural finish.
❌ Cause discolouration, especially with repeated use.
❌ Leave residues that block new sealer bonding.

Cleaning And Sealing Products offers granite-safe removers that:

✔ Remove failed sealers safely and thoroughly.
✔ Leave no harmful residue for resealing.
✔ Work quickly to restore granite’s natural beauty.

If your granite shows flaking, discolouration, or peeling from a bad sealer, remove it properly to avoid lasting damage. Using the right remover and sealer, and applying them carefully, helps keep granite beautiful and strong for many years.
