Types of Sealers for Concrete Driveways

Concrete is the most common material used on driveways and other outdoor structures because of its durability. It performs well on its own even without adding chemicals and other stuff on it. However, it definitely lasts longer when a good quality sealant is applied to it. Concrete sealers protect the surface of your driveway, protecting it from moisture damage, scratches and other external factors.

With so many types of concrete sealers in the market, choosing the right one can be quite a challenge. Read along to know which type suits your needs.

Penetrating Sealers

Penetrating sealers are the most popular choice when you’re looking for one that offers great protection. It is made from a blend of speciality resins which penetrate deep into the concrete slab. This forms a strong chemical barrier against moisture, dirt, oil and other factors. Penetrating sealers are the perfect choice for surfaces that are exposed to a lot of damaging factors – driveways, garage, factory flooring and other similar surfaces. For perfectly sealed concrete, hire an expert to do the project. Our professional team of workers offer the best concrete sealing services in all Sydney areas.

Acrylic-Resin Based Sealers

This type is one of the costly ones but its performance is definitely worth it. Acrylic-resin based sealers are durable and they can be combined with other substances such as epoxy or silicone to enhance its performance more. Styrene acrylic is the least performing type which turns yellow in the long run when exposed to direct sunlight. If you don’t like your driveway to get discoloured, later on, choose pure acrylic resin instead. It lasts longer than styrene-acrylic and doesn’t change colour.

Epoxy Sealers

Epoxy sealers, also known as polyurethane sealers, cost more than acrylic-based ones. However, it doesn’t mean that they are the best sealer that would fit your needs. Epoxy sealers leave a thicker layer compared to acrylic-based ones. This sealer might not be a good option if you’re planning to seal a walkway or a patio because it can get slippery when wet. Because of its structure, epoxy sealers don’t allow the concrete to breathe out moisture from within which leads to the formation of a white haze in between the concrete and epoxy layer.

Choosing the Gloss Level of a Sealer

Concrete sealers also have gloss levels just like paint. The glossiness of your chosen sealer depends on which surface it will be applied. You can choose from high gloss down to no gloss options. The gloss level is indicated in every sealer so make sure to check it first before buying one. Glossiness levels range from 1 to 100, with 100 as the glossiest. Penetrating sealers don’t leave any gloss on the surface because it is absorbed deep into the concrete slab. Water-based concrete sealers can range from matte to semi-gloss while solvent-based ones are the glossiest ones. However, solvent-based ones tend to darken a surface, making it a perfect choice if you want to seal and stain a slab of concrete at the same time.

Having these basic insights about concrete sealers definitely helps a lot if you want to make your driveway or any other concrete surface last longer and look perfect always.
