Concrete is one of the topmost useful materials utilized in construction today. Typically composed of water, Portland cement and aggregate (rock or sand), concrete holds up well under pressure. However, its porosity makes it susceptible to wear and tear. Contaminants such as dirt, oil, acid rain, and more can permanently affect the outer appearance and structural integrity of the concrete. It is therefore essential to use a decorative concrete sealer. No concrete project is finished without the installation of a sealer.
Decorative concrete sealer is beneficial for many reasons discussed below:
They come in a sheen range from matte to high-gloss, adding just the right touch to your concrete surfaces; The decorative concrete sealer helps in blocking the penetration of chemicals, dirt, mould, water, UV rays and more; Reduce musty odours, cracking, spalling, efflorescence, and crumbling
The decorative concrete sealer makes the concrete easier to clean, maintain, and increase your concrete’s durability, making your investment last longer; Can penetrate deep into the surface, densifying your concrete and protecting it from harmful freeze-thaw cycles, rust corrosion and more. Not only do the decorative concrete sealer protect your concrete, but also can beautify decorative concrete surfaces by making the colours’ pop’ even more;
There are various types of decorative concrete sealer, and they include;
They are either water or solvent-based and are a ‘film-forming’ top coat sealer. They do not penetrate the concrete; instead, they form a protective film on the surface. Acrylic decorative concrete sealer is formulated for interior or exterior use, but solvent-based acrylics may be more ideal for exterior use as they can be more durable.
They are also available in water or solvent-based formulas and maybe one or two-component kits. Although they are also film-forming sealers, they are not as soft as an acrylic sealer and will provide excellent protection from chemicals and abrasives. Polyurethane decorative concrete sealer can be used on interior or exterior surfaces and can even be used on concrete countertops.
They create a hard, long-lasting finish. The higher the solids content, the stronger the finish. Epoxy decorative concrete sealer is generally suggested for indoor use as they do not resist UV. You may be able to treat the epoxy with a UV resistant coating if exterior use is necessary. Most are two-component kits that you mix just before applying. Some epoxies may be ‘tinted’ with pigment to provide a semi-transparent colour. Epoxies are also a film-forming sealer and can be very slick when wet.
They do a good job of strengthening your concrete surface from the inside. The tiny particles can pierce and then seal the substrate permanently as they expand into the pores of the concrete, leaving a waterproof finish.
There are several different types of penetrating sealers. Some are ‘paintable,’ and some are not, meaning they may permanently seal your concrete so thoroughly you will be unable to get paint, stains, and dyes. Penetrating decorative concrete sealer does not typically change the surface appearance but may become slippery when wet.
Protect your investment with a decorative concrete sealer and enjoy the outcome for many years to come!
