How to Seal Flagstone Around Pool

Pool lovers know that pools require a lot of maintenance and upkeep. However, pool owners often forget to seal the flagstone around their pool every year or so. The most common way to do this is with a spray-on sealant, but you can also use a paint roller.

How to Seal Flagstone Around Pool

Make sure you clean your flagstone first by scrubbing it down with a wire brush and then washing it off before applying the sealant or paint on it! So, this article is for you. You will learn how to seal flagstone around pool with just one simple trick!

Step to Follow on How to Seal Flagstone Around Pool

Step One: Determine the type of material.

Before sealing flagstone around the pool, one has to determine what kind of material it is. If the slate is dry, it needs to be hydrated before applying an impregnator; if wet, the sealer can be directly applied.

When working on large areas of stone, always start in a small section to get a feel for the material and what it requires. Cracks and seams should also be sealed if they appear. These can be filled with natural sand before applying sealer to the surrounding surfaces.

Step Two: Protect surrounding areas.

To protect surrounding materials from the impregnator, place a drop cloth or plastic sheeting over them. The sheeting should extend at least twelve inches beyond stone on all sides. Be sure to check for small cracks or seams before sealing flagstone around the pool so these areas can be treated accordingly.

If the surface is not dry, it is likely already hydrated and needs to be treated with an impregnator. However, if the flagstone is very dry or has cracks, one should use a solvent before sealing the flagstone around the pool for better penetration.

Step Three: Prepare area to be treated

To prepare the area to be impregnated, rinse it thoroughly with water. If the stone is dry, then use a solvent so the material will absorb the sealer better. After this, apply an impregnator to give off crystals that will saturate and seal pores in the flagstone.

Cleaning Pool Area Before Sealing

When using impregnators on outdoor surfaces, especially around poolside areas, it is recommended that one does not seal flagstone around the pool when temperatures are below fifty degrees Fahrenheit.

Step Four: Rinse the surface thoroughly

After the impregnator has been applied, allow time for it to dry completely. After drying, apply a light scrubbing with a stiff bristle brush to remove any excess residue from the surface. Then rinse the flagstone thoroughly with water to be ready for another coat of sealer or to use immediately.

If possible, the number of coats of sealer should not exceed three. After this, the flagstone is recommended to be sealed every two years for maximum protection and performance. Flagstones should never be sealed during winter months when temperatures are below fifty degrees Fahrenheit.

Step Five: Apply a second coat of sealer

After allowing the first coat of sealer to dry completely, use a sponge or light-weight cloth to apply a thin coat of the material in order to add to the effectiveness and protection of the flagstone. Allow this second coat to dry entirely before re-applying any more sealer.

If the flagstone is porous, cracks are present, or other conditions exist, one should use an impregnator before applying sealer. Apply solvent first, then impregnator according to directions on the container. Allow time for drying before moving on to step three.

Step Six: Re-apply sealer if necessary

If one is satisfied with the amount of protection the flagstone currently has, then it does not need to be resealed. If, however, deeper penetration and better protection are desired, follow steps three through five until this is achieved.

After applying an impregnator and solvent as necessary, allow time for drying. Then it is recommended that one place a drop cloth or plastic sheeting over the surrounding area as described in step two and as far as necessary to protect any other materials from the sealer.

Step Seven: Scrub surface

When the impregnator has dried, scrub the flagstone thoroughly with a stiff bristle broom or brush. This will remove any excess material that may not have penetrated the stone and ensure maximum penetration for better performance.

Scrub With Bristle Brush to Clean

Wash off all remaining residue with water after scrubbing. If possible, use clean water to rinse the flagstone and surrounding area further. Sealing sandstone around a pool is similar to sealing any other porous surface. This will help in how to seal flagstone around pool.

Step Eight: Re-apply sealer.

After allowing the flagstone to dry completely, apply another coat of sealer using a sponge or cloth. Allow time for drying and then apply a second coat if necessary. Continue this process until the desired results are achieved.

If no impregnator is used before starting, one can use an impregnator after the first couple of coats have dried. Apply impregnator following directions on the label before applying sealer. After this, allow the flagstone to dry before applying another coat of sealer.

Step Nine: Rinse all residue.

After allowing the final coat of sealer to thoroughly dry, rinse the flagstone and surrounding area with water so it will be ready for use or additional coats of sealer. This will ensure that all excess material is removed from the area.

Ready for Use After Rinse All the Residue

Flagstone is porous and requires special care when sealing it. If one follows these steps carefully, however, they will be able to seal flagstone around their pool with success. Flagstones are common in many areas of the world and can add a new dimension to any landscape.

Conclusion

With the right tools, you can seal your flagstone around the pool. First, you’ll need a high-pressure cleaner with an attachment to remove dirt and algae from the surface of the stone.
