The benefits of using water-based sealers

Decorative concrete coatings have become increasingly popular over the years and for good reason. Not only do they offer a unique and beautiful finish, but they also provide numerous benefits such as durability, ease of maintenance, and versatility in design.

However, to ensure that these benefits are fully realized, it is essential to properly seal the coating. In this blog, we will explore the benefits of using a water-based sealer to seal decorative concrete coatings.

What is a Water-Based Sealer?

A water-based sealer is a type of sealer that is made from water-based acrylic polymers. These polymers are designed to penetrate the surface of the concrete coating and create a protective barrier against stains, chemicals, and other elements that can cause damage to the coating.

Water-based sealers are available in a range of finishes including matte, satin, and glossy, making them a versatile choice for any decorative concrete coating.

Benefits of Using a Water-Based Sealer

Environmentally Friendly

One of the most significant benefits of using a water-based sealer is that it is environmentally friendly. Unlike solvent-based sealers that emit harmful chemicals into the atmosphere, water-based sealers are low in volatile organic compounds (VOCs).

VOCs are known to be harmful to the environment and can also have adverse effects on human health. By choosing a water-based sealer, you are doing your part to reduce your carbon footprint and protect the environment.


Another benefit of using a water-based sealer is that it is non-toxic. Solvent-based sealers contain harmful chemicals that can be hazardous to human health, particularly if they are not used in a well-ventilated area.

In contrast, water-based sealers are non-toxic, making them a safer choice for both the environment and human health.

Easy Application

Water-based sealers are incredibly easy to apply, which is a significant advantage for DIY enthusiasts. They can be applied with a brush, roller, or sprayer and do not require any special equipment or training.

This means that you can achieve professional results with minimal effort and without having to hire a professional.

Quick Drying Time

Water-based sealers have a quick drying time, which is another benefit for those who want to complete their project quickly. They typically dry within a few hours, allowing you to walk on the surface or apply a second coat within a short period.

This is particularly useful if you are working on a project with a tight deadline. However, if rain is threatening, you need to be cautious as water-based sealers need to have at least 8 hours of drying time to ensure it doesn’t re-emulsify or go white.

Enhances the Appearance

Water-based sealers can enhance the appearance of decorative concrete coatings by adding depth and richness to the colours. Our product W881 Sealer is good at this and is a colour-enhance sealer.

They can also create a low gloss or low matt finish that reflects light and adds a luxurious low sheen to the surface. This is particularly important for outdoor applications, where the natural light can highlight the beauty of the decorative concrete coating.


Water-based sealers are durable, making them an ideal choice for high-traffic areas such as driveways, patios, and walkways. However, they may not be as durable as a solvent-based topical acrylic sealer as they are not as hard-wearing.

They provide a protective barrier against stains, chemicals, and other elements that can cause damage to the surface. Sealing means that the decorative concrete coating will last longer, reducing the need for costly repairs or replacements. Bear in mind all sealers break down over time and therefore it is necessary to have a maintenance plan and to reseal the area when it needs it.

Low Maintenance

Water-based sealers require minimal maintenance, making them a practical choice for busy homeowners. They can be cleaned with mild soap and water and do not require any special cleaners or equipment. This means that you can enjoy your decorative concrete coating without having to worry about extensive maintenance or upkeep.


Water-based sealers are incredibly versatile, making them suitable for a wide range of decorative concrete coatings, all kinds of concrete, natural stone, burnished concrete and polished concrete.

They can be used on both indoor and outdoor surfaces, including concrete floors, concrete countertops, vertical surfaces, and more. They are also available in a range of sealers, making it easy to achieve the desired look for your project.

Additionally, water-based sealers are compatible with a range of decorative concrete coatings, including stamped concrete, acid-stained concrete, coloured concrete, and polished concrete.


Using a water-based sealer to seal decorative concrete coatings can also be cost-effective. Water-based sealers are typically less expensive than solvent-based sealers, which can be a significant advantage for those on a budget. Our sealers are also concentrated and can therefore cover a much greater area which reduces the cost /m2.

Additionally, since water-based sealers require less maintenance and provide excellent durability, they can help save money in the long run by reducing the need for costly repairs or replacements.

Safe for Indoor Use

Another benefit of using a water-based sealer is that it is safe for indoor use. Since water-based sealers do not emit harmful chemicals or odours, they are ideal for use in enclosed spaces such as basements, garages, and other indoor areas.

This means that you can enjoy the benefits of a decorative concrete coating without worrying about the health and safety of your family or pets.

How to Apply Water-Based Sealer

Applying a water-based sealer is a straightforward process that can be completed in a few simple steps:

  1. Pressure Clean the Surface: Before applying the sealer, make sure the surface is clean and free from any debris or dirt. This can be achieved by sweeping, vacuuming, and pressure cleaning the surface. A mild detergent and water can also be used to clean any stubborn dirt.
  2. Apply the Sealer: Using a brush, roller, or sprayer, apply the sealer evenly to the surface over a 5-10m2 area. Then use a roller to cross-hatch the sealer. Use two coats and apply the rolling technique in the opposite direction when rolling on each coat of the sealer. It is important to dilute the sealer as directed and also avoid applying too much sealer, as this can lead to a cloudy or hazy appearance. Do not leave puddles of sealer on the surface to dry. Remove excess sealer with a broom, squeegee or mop.
  3. Allow to Dry: Allow the sealer to dry for the recommended time, usually a few hours, but may vary depending on the associated conditions.
  4. Apply Multiple Coats If Necessary: If desired, a second or third coat of sealer can be applied, or more, to enhance the appearance and to build up the integrity and durability of the coating.


In conclusion, using a water-based sealer to seal decorative concrete coatings offers numerous benefits, including environmental friendliness, non-toxicity, easy application, quick drying time, enhanced appearance, durability, low maintenance, versatility, cost-effectiveness, and safety for indoor use.

By choosing a water-based sealer, you can protect your decorative concrete coating while also enjoying its beauty and functionality for years to come.
