Should New Concrete Be Etched Before Sealing?

Should New Concrete Be Etched Before Sealing?

Yes, etching is always recommended. This will create a bond between the new concrete and the sealer, preventing cracking that can happen without etching. Before sealing a new concrete patio, it is important to etch the surface in order to ensure proper adhesion of the sealant.

When concrete is first poured, it is very smooth and dense, making it difficult for the sealant to penetrate the surface and form a strong bond. Etching the surface roughens it up and creates microscopic pores that allow the sealant to penetrate more easily, resulting in a stronger and more durable seal.

Surface preparation is critical before applying a sealer to existing concrete. All oil, grease, stains, filth, and dust must be removed or the sealer will not adhere correctly. Furthermore, if a sealer is being put over another brand of sealer, most manufacturers recommend removing any evidence of previously used sealers, as the products may not be compatible.

Does Sealing Concrete Make It Slippery?

No, concrete sealers are used to preserve the surface of concrete against deterioration, corrosion, and discoloration. They either seal the pores in the concrete to limit water and salt absorption or build an impermeable coating that stops such elements from going through.

The surface may become slick if you apply low-quality concrete sealers. Some sealers have a high solid content, which allows them to cover the pores on the concrete. In that instance, a solid layer forms on the pavement’s surface, which becomes slippery when wet.

The application technique is another major component that contributes to the slippery character of the pavement. Even if a high-quality sealer is used excessively, a continuous top layer will grow, which will become slippery when wet.

As a result, property owners must choose skilled technicians that understand the finest concrete sealing processes. Concrete’s slick characteristic may be avoided with the proper application technique.

Consult with concrete sealing professionals who will analyze the hardscape and offer the best sealer that will not affect the traction level of your concrete.

Does Sealing Concrete Make It Look Wet?

No, when concrete is sealed, it does not necessarily make it look wet. However, depending on the type of sealer used, it can give the concrete a glossy or wet appearance. The main purpose of sealing concrete is to protect it from weathering, staining, and other environmental elements.

When sealing concrete, it is common for the surface to take on a wet appearance. This is due to the resins in the solvent-based acrylic sealer reacting with the concrete to create a dark, glossy finish.

While this may not be the most aesthetically pleasing look for some, it does serve to protect the concrete from further damage. The two best products for creating a wet look on concrete are the Armor AR350 and the Armor AR500.

The key to getting the best results is finding a professional contractor that knows how to properly apply this type of sealer at the right thickness. A thin application will not show as much depth as a thick application.

Does Sealing Concrete Prevent Moisture?

Yes, sealing concrete will prevent moisture from going into the concrete. However, it does not keep it out. Concrete surfaces can absorb significant amounts of moisture during certain weather conditions. When this happens, the water can cause staining and other problems for both new and old concrete surfaces.

Water leaking through concrete flooring in a basement or garage exposes your property to major issues. This water might impair your home’s structural integrity and function as a catalyst for the growth of hazardous mold and mildew.

With continual moisture exposure, a minor fracture in a concrete wall may grow into a major issue, allowing insects and the weather into your home.

Preventative maintenance includes sealing your home’s concrete surfaces. Taking care of your house’s concrete before an issue arises is critical to maintaining the indoor air quality and fundamental integrity of your property.
