San Antonio Concrete Sealing

Concrete sealing is a protective treatment applied to concrete surfaces to enhance durability, resist staining, and extend the life of the material. Whether used on driveways, patios, walkways, garage floors, or interior slabs, sealing helps safeguard concrete from moisture, chemicals, UV exposure, and everyday wear. A properly sealed surface maintains its appearance longer and is significantly easier to clean and maintain.

Why San Antonio Concrete Sealing is Needed

Concrete is naturally porous. Without protection, it absorbs water, oils, salts, and other contaminants that can lead to:

• Surface staining
• Cracking from freeze–thaw cycles
• Spalling or flaking
• Premature deterioration
• Mold or mildew growth in damp areas

Sealing creates a barrier that prevents these issues and preserves the structural integrity and appearance of the concrete.

Types of Concrete Sealers

1. Penetrating Sealers

• Absorb into the concrete to create long-lasting protection.
• Ideal for exterior surfaces exposed to weather.
• Provide a natural, non-gloss finish.
• Excellent resistance to moisture, salt, and freeze–thaw damage.

2. Acrylic Sealers

• Form a thin protective film on the surface.
• Available in matte, satin, or high-gloss finishes.
• Enhance color and provide a wet-look effect.
• Commonly used on decorative concrete, stamped concrete, and patios.

3. Epoxy and Urethane Sealers

• Create a thick, durable coating.
• Highly resistant to chemicals, abrasion, and heavy traffic.
• Popular for garage floors, warehouses, and commercial spaces.
• Offer a glossy, polished appearance.

The Concrete Sealing Process

1. Cleaning and Preparation

• The surface is thoroughly cleaned to remove dirt, oil, stains, and debris.
• Any cracks or damage are repaired.
• Old sealers or coatings may be stripped if necessary.

2. Application of Sealer

• The chosen sealer is applied using a sprayer, roller, or brush.
• Coverage depends on the type of sealer and the porosity of the concrete.
• Multiple coats may be applied for enhanced protection.

3. Drying and Curing

• The surface must remain undisturbed during drying.
• Full curing time varies from a few hours to several days depending on the product.
