Applying sealer on flagstone is important for protection, though a poorly done job means resealing will be necessary. However, the previous sealer should first be removed – so how does one remove sealer from flagstone?
Flagstone should be cleaned thoroughly using a damp cloth to get rid of dirt and debris. Once dry, pour a sealer stripper designed for use on flagstone, then use a stiff brush to agitate the surface without allowing it to dry, unless otherwise specified by the manufacturer. Wipe the surface clean.

Here’s a list of the equipment you’ll need, which are available on Amazon (note: we earn a small percentage if you decide to buy these products, which goes to maintenance of this site and helping readers like you):
- Sealer stripper or remover that is made for flagstone surfaces. Choose a formula that is compatible with the previous sealer’s formula.
- Stiff-bristled cleaning brush, which helps efficiently spread the stripper on the flagstone surface while agitating it for the best results. A brush with a long handle is recommended for comfort and convenience.
- Chemical-resistant hand gloves are critical because they will protect your hands from exposure to the chemicals in most sealer removers
- Cleaning cloths, which will be used to wipe down excess sealer remover. White is always recommended because colored towels may bleed onto the surface.
The process for removing sealer from flagstone is the same for most products; this is what has been outlined below. However, some sealer strippers may have specific directions which should always be followed.
- Pour a liberal amount of sealer stripper on the flagstone surface
- Use the brush to spread it evenly on the surface, without allowing it to dry. Continue agitating it for up to an hour until the sealer has visibly softened.
- Wipe the surface dry with a clean, white cloth.
- Repeat steps 1-3 if the sealer has not been completely removed.
- Rinse the flagstone surface thoroughly with clean water once done.
Allow the flagstone surface at least one hour to completely dry, or until the fumes have completely evaporate, until exposing it to traffic. Allow it to dry then cure for at least 24 hours until you reapply a sealer or finisher.
With these helpful tips, you can now easily remove sealer from flagstone. Always remember to double check the sealer manufacturer’s directions before getting started.
