Why Slate Needs Sealing

Slate is a unique natural stone with rich colors and a beautiful textured surface. It is often used around pools, patios, steps, and entryways because of its appearance and grip. But slate also has vulnerabilities that many homeowners underestimate. Because it is naturally layered, it can delaminate when moisture seeps in and expands during hot and cold cycles.

Slate is porous enough to absorb water, salt, and oils, which can cause stains, flaking, and erosion over time. UV rays in sunny Texas weather can fade the surface, making it lose its original character. Chlorine from pools and salt from coastal air or hard water accelerate damage even more. Without sealing, slate can begin to look dull, stained, or cracked after just a few seasons.

How Professional Cleaning Prepares Slate

Before applying a sealer, slate needs to be thoroughly cleaned. This is one of the most important steps. If dirt, mineral deposits, or algae are trapped underneath a sealant, the stone will continue to break down from the inside. Professionals use specialized cleaners to remove stains and buildup without damaging the stone’s surface.

This cleaning process may include a light pressure wash, an alkaline or neutral cleaner, and in some cases a descaler to remove mineral buildup. The goal is to bring the stone back to its natural condition so the sealer can penetrate evenly and deeply. Once the slate is fully cleaned, it must be allowed to dry completely before sealing begins.

Choosing the Right Sealer for Slate Sealing

Not every sealer is right for slate sealing. Homeowners often pick up generic sealers at a hardware store, but these products can cause peeling or uneven finishes. TSS Pro Sealants offers professional-grade sealers designed for natural stone, including slate.

• TSSPRO 100 Natural Look Sealer is a strong solvent-based option that protects against saltwater erosion and UV rays while maintaining the natural color of the stone.
• TSSPRO 500 Enhancing Sealer is a water-based option that enhances color with a matte finish. It’s ideal for patios and pool decks where appearance matters.
• TSSPRO 600 Weatherproofing Sealer is a premium option for harsh exposures. It penetrates deep into the stone and creates a barrier that stands up to extreme conditions.

Using the right sealer ensures the stone remains breathable while still being protected against moisture and staining.

Application Process

Once the surface is clean and dry, the sealing process begins. Professionals apply the sealer with rollers, sprayers, or brushes to ensure even coverage. Depending on the porosity of the slate, one or two coats may be required.

During application, technicians carefully watch how quickly the stone absorbs the product. If it soaks in fast, a second coat may be applied shortly after the first. Coverage rates typically range from 150 to 250 square feet per gallon, depending on the product and condition of the stone.

Curing time is also critical. Even though the surface may appear dry to the touch, sealers need time to bond deeply. Homeowners should avoid foot traffic or water exposure until the recommended cure time has passed.

Benefits of Sealing Slate

When slate sealing is properly done, it offers many advantages:

• Water beads on the surface instead of soaking in
• Colors appear richer and stay vibrant over time
• Stains and algae are easier to clean off
• Flaking and delamination are reduced
• Surfaces resist UV fading and saltwater damage

For homeowners, this means less maintenance, fewer repairs, and a cleaner, safer surface. For contractors, it means satisfied clients and surfaces that last longer without premature failure.

Maintenance Tips After Sealing

Even with a professional sealer, slate should be maintained properly. Homeowners should:

• Keep surfaces clean and rinse away dirt or salt buildup
• Avoid harsh acidic cleaners that can break down sealers
• Reapply sealer when water no longer beads on the surface, typically every few years
• Schedule periodic inspections to catch minor issues before they turn into major repairs

Cost and Long-Term Value

While sealing slate does have an upfront cost, the long-term savings are substantial. Without sealing, slate can crack, fade, or delaminate and require expensive repairs or replacement. With sealing, it can last for many years with only basic maintenance.

A properly sealed slate patio or pool deck also improves curb appeal, which can increase property value. This is especially important in Texas where outdoor living spaces are a major feature of many homes.
