Why Sealing Slate Stone Is Necessary for Shower Floors
Natural slate tiles look amazing, they are simple, durable and timeless. However, in a wet, high traffic shower they are a risk to:
- Water Absorption: Due to its porous surface, slate absorbs the moisture, resulting in mold, grout worn out and white, powdery salt deposit also known as efflorescence.
- Staining: Froth from soap, shampoo, and hard water carve into unsealed surfaces quickly, leaving rigid stains behind.
- Slipperiness: When wet, unsealed slate gets super slippery, increasing the risk of slip-and-fall.
Sealing a slate floor helps repel water, protect from stains and enhance color depth without damaging the stone’s natural texture. How? Well, it protects the surface by creating a hydrophobic barrier. If done properly, your slate floor sealer can last 3 to 5 years, or more in low-use areas.
To know whether your shower floor needs immediate sealing, test a small spot with water. This will help you know your slates porosity. If the floor gets dark or absorbs water in under 5 minutes, seal slate stone ASAP.
Best Slate and Tile Sealer Options
Due to slate being naturally porous, permanent sealing is not possible. However, these few options come closest:
- Penetrating: This slate sealer is most recommended for showers, they last 3 to 5 years and give a natural/matte finish.
- Topical: This one is best for dry areas only, lasts 1 to 2 years and provides a glossy/wet look.
- Hybrid: This option works great for high traffic showers, lasting 4 years, and giving a low sheen finish.
Why penetrating sealers are a win
