Failed Sealer - Slate

Our failed sealer removal products are specifically formulated to tackle sealer issues on slate, a stone that requires careful treatment due to its layered composition and occasional iron content. When sealers on slate begin to deteriorate, leading to discoloration, whitening, or an uneven finish, choosing the correct removal product is essential to avoid affecting the stone’s natural appearance. For minor sealer issues, products like xylene can help re-emulsify and lift certain types of sealers, allowing trapped moisture to escape and restoring the bond without damaging the slate.

In cases where full sealer removal is required, a slate-safe stripping product is recommended to prevent surface damage. Using harsh acids or incompatible products can lead to unwanted etching or rusting if the slate contains iron, so it’s vital to read product descriptions and follow application guidelines carefully. Testing a small area before full application is also advised to confirm compatibility.
