How to future-proof your concrete floors

How to future-proof your concrete floors

Concrete sealer is one of the best ways to improve the longevity of residential and commercial concrete under duress.

Concrete sealers are a substance which prevents salts and water from being absorbed by the concrete. The sealant will achieve this one of two ways: the first by blocking the pores of the concrete, and the second by forming an impermeable layer through which salts and water cannot pass. The second type of concrete sealer is known as ‘film-forming’ and it is the most common for residential use. Film forming concrete sealers come in three different types: acrylic, polyurethane, and epoxy.

Concrete sealers are extremely effective at protecting concrete in the long term. They help concrete surfaces to endure and resist weather exposure, water damage, grease and oil stains, abrasion, salts, cracking, chipping, expansion, and even just general wear and tear. They are an important part of concrete maintenance and concrete should be sealed every 2-5 years to protect it from such damage. On top of the practical benefits, concrete sealants also help to improve the aesthetic appeal of the concrete, often adding a glossy or matt finish that makes the flooring appear newly set.

How to seal concrete

Sealing concrete is an inexpensive and straightforward job, making it a popular choice for DIY projects. The sealers themselves are affordable and commonly available in most major hardware stores such as Bunnings. Before purchasing a concrete sealant for your home, you will need to consider the different types and how they best apply to your situation. The different types of concrete sealers are:

Film Forming

1. Epoxy

Epoxy concrete sealers are the most popular because they are extremely durable. Epoxy concrete sealer works well indoors, particularly in high traffic retail environments or undercover garages.

2. Acrylic

Acrylic sealers are somewhat softer than epoxy concrete sealers and they require a sacrificial floor wax. Acrylic concrete sealant is best suited to residential concrete floors, such as polished concrete kitchen floors, concrete benchtops, or basement floors.

3. Polyurethane

Polyurethane sealant is more robust and often used in industrial/construction settings to seal joints. This style of sealant is best suited in high traffic areas such as retail environments (due to its durability) or concrete countertops. It is also a popular driveway sealer.

Polyurethane concrete sealer is also known to enhance the aesthetic appeal of certain concrete types, such as coloured concrete or stamped concrete.


Penetrating sealers are best suited for outdoors and provide a natural finish that will not impact the overall appearance of the concrete. Penetrating sealers include silanes, siloxanes, and silicates which permeate into the concrete to form a chemical barrier by sealing the internal pores. Penetrating sealers are extremely durable, making them the popular choice for outdoor use as they can defend against weather like rain exposing concrete to high levels of water.
