Videos of how to apply a water-based sealer

Sealing your concrete at home is not as hard as you think. All you need is the right product, tools, and know-how to apply it.

If you have a pressure cleaner, a garden sprayer or airless sprayer, containers to mix the sealer, and a paint roller you can DIY! You can learn how to apply a concrete sealer with a roller!

Let me take you through the simple steps of applying a water-based sealer to your driveway, patio, pool, paths or house surrounds.

First, buy a sealer from our online shop. Read the blog to learn more about which sealer may be right for you. Or contact us, we are here to help you with your project.

Second, all our water-based sealers are concentrated, therefore, dilute the product in a 1:3 ratio, dilute 1 part product to 3 parts water.

Third, pressure clean the concrete area you are going to sealer with the water-based sealer. If the concrete is new or already clean, wet it down as all our sealers are wet application sealers. A wet surface helps the product to draw into the surface.

Fourth, Fill your spray device with the diluted sealer mixture and spray onto the surface generously as in the first video below. Spay a workable area about 3x3m2. It’s best to apply the sealer in sections.

Fifth, once you have sprayed on the sealer take your paint roller and backroll the sealer just like in the second video. You can also use a microfibre mop or an industrial broom too, however, we have found that the backrolling technique works best.

This helps evenly spread the sealer and helps it to penetrate into the surface. You will notice after a few minutes that the sealer will start to disappear and the concrete will return to a natural finish. This can take 15-30min. As soon as it’s clear, apply the second coat of sealer.

Note that sealing is generally a two-coat system, the first coat is for penetration and adhesion, the second coat is for the resistance and integrity of the coating. For best performance, you can do up to four coats depending on all the associated conditions.

Note that the sealer may perform differently on different concrete surfaces, if it’s more porous more sealer may be applied, if it’s very tight concrete, you can dilute it thinner by trying a ratio of 1:4 or 1:5 etc. Please ensure you read the product data sheet, the technical data sheet, the material data sheet and all associated conditions. You are also welcome to call us to discuss your project with us, we are here to help.

The videos are very basic, but you will know how to do it yourself once you have seen how an applicator applies the water-based sealer.
