Concrete is a commonly used material, from manufacturing and construction to decorative purposes. Most structures and buildings rely on concrete to keep them safe and sturdy, but there’s one setback to this one-of-a-kind structural medium: it absorbs water, making it susceptible to damage. An effective way to prevent this is by applying a sealer on the surface of the concrete.

What is a Concrete Seal?

A sealer acts as a barrier preventing water or other liquids from penetrating the surface and absorbing harmful chemicals. These additional protective layers slow deterioration in the long run and protects your concrete against carbonation, salt damage, alkali-silica reaction, weather degradation, and rusting. Concrete sealing consists of three main processes: surface preparation, product application, and drying time. Here are some common types of sealers for concrete.

Silicone Sealers

Silicone sealers are made from high-quality materials, making them durable, efficient, and cost-effective. The unique traits make silicone sealers ideal for protecting against rusting, wet conditions, and salt damage. These sealers also have excellent elasticity, allowing the surface to restore its former state even after movement caused by natural factors or pressure over time. There are two types of silicate-based sealers: epoxy resin and acrylic polymer sealers.

Chemical Resistant Sealers

If you work in a facility exposed to chemicals, this is the right concrete sealer to use. Chemical-resistant sealers are specifically designed to protect concrete against harsh, highly-corrosive elements such as acid, making it ideal for the chemical industry. Most facilities that deal with chemicals have constant traffic, which takes a toll on the structural integrity of the concrete. Chemical-resistant sealers are applied in heavy-duty applications because of their durability, preventing further damage to the concrete.

Polyurethane Sealers

This is the most commonly used type of sealer in protecting concrete because it can be used in interior and exterior structures. Polyurethane sealers are considered superior performance because of their excellent flexibility even after curing on the concrete surface. The elastic nature of these sealers makes them flexible and durable enough to handle movements that occur on concrete surfaces. Since regular polyurethanes can withstand the pressure of high traffic, most people use them in spaces lined with the constant movement of people.

Why do You Need Concrete Sealing

There are several reasons why concrete sealants are crucial, whether protecting your home’s patio from outdoor elements or having a beautiful concrete surface for commercial benefits. First, concrete sealers prevent dust accumulation, leading to the discoloration of colored coating on surfaces.

Second, using a concrete sealer for various surfaces helps prevent damage caused by weather conditions, such as cracks affecting a structure’s aesthetics. Cracks also compromise the durability and structural integrity of your concrete surfaces: the more reason to consider concrete sealers. Lastly, applying concrete sealers prevents staining on concrete surfaces by grease, oil, and other dirt that stick to your structures. 

If you are looking for a way to protect your concrete surfaces and enhance their durability and aesthetic appeal, you should consider waterproofing. This guide will help you ask the right questions and make informed decisions based on your concrete needs.
