Concrete Sealing: Frequently Asked Questions

You may have been told that it is important to have concrete sealing done on your various surfaces, but do you know why? Many people understand that they probably need a concrete sealer, but are unsure of which one to choose, how to apply it, and a range of other answers to concrete sealing questions.

Luckily, the experts from Quickly Please Cleaning, who knows a thing or two about concrete sealing, are here.

Read on to understand a little bit more about sealers with answers to some of the most common questions we receive from our customers.


What types of surfaces should I seal?

We always recommend sealing any exterior concrete as it cops the heaviest brunt in terms of foot traffic and exposure to the elements.

Concrete sealing helps with stain repellency, dust reduction, abrasion and chemical resistance and upholding the as-new appearance of your concrete.


What happens if I don’t seal my concrete?

As concrete is extremely porous, it absorbs liquids with ease. Exterior concrete is often exposed to oil, salt, fertiliser, and other chemicals that will discolour and damage unsealed concrete. Concrete sealing also makes your surfaces much easier to clean.


How much will the concrete sealing cost?

You first need to keep in mind that concrete sealing is an investment that pales in comparison to the costs of replacing the damaged concrete.

It is also important to note that the incorrect application of sealant, of the wrong type of sealant, can cause more harm than good.

For this reason, you should work the cost of professional concrete sealers into your costs. This also provides the benefit of saving you the time of performing the job yourself. Time is money, after all!


What will my concrete look like after it has been sealed?

The finished look of your concrete will vary based on the type of sealer you apply. If you are using a chemically reactive sealer, the finish will be nearly invisible as they penetrate deep into the concrete, avoiding a shade change on the surface.

If you are using a solvent-based acrylic resin sealer, they will likely enhance the colour of your concrete surface. This often gives the look of a wet or high-gloss finish. 

Water-based acrylic resin sealers create a similar look, albeit a little more subtle with a moderate colour enhancement and a satin finish.

Finally, a urethane coat applied as a topcoat over epoxy offers a range of finishes, including matte and gloss. In some cases, sealers can be coloured with translucent or opaque tints.


Can I DIY my concrete sealing?

You can DIY your sealer with a paint roller or pump-up sprayer if you are using acrylic-resin sealers, reactive penetrating sealers, or a 50%-solid epoxy or solid urethane sealer.

If you are opting for a high-performance sealer such as 100%-solids epoxy or polyaspartic urethane, professional installation is a must due to the requirement of specific tools and application techniques.

The cost of saving yourself time, ensuring the correct sealer and application process, and the peace of mind in knowing the job has been done correctly, however, is often reason enough to opt for professional sealing.


When should sealer be applied?

It’s always best to apply your sealant as soon as your new concrete is able to be walked on. If you are using a reactive penetrating sealer or high-performance coating, it’s best that your concrete has fully cured for about 28 days. 


What will sealer protect my concrete from?

This once again comes down to the type of sealer you choose as some are better suited to repelling water and others better for oil stains. Some sealers will also degrade quicker when they come into contact with certain chemicals.

A high-performance epoxy or urethane system is your best bet for an all-rounder. Essentially, sealers work to protect your concrete from staining and degradation against the standard elements it can come into contact with.


Will my concrete be slippery as a result of the sealer?

Your concrete surface profile and traction is usually untouched when it comes to a sealer. Some topical coatings may require the use of an anti-skid additive if the area experiences a lot of foot traffic, but for the most part, there will be no major effect on how slippery your surface is.


How long will the sealer last?

Reactive chemical sealers last the longest at around 10 years or longer depending on what the surface is exposed to. An epoxy or urethane system generally lasts 5 to 10 years, and acrylic-resin sealers will last around 1 to 3 years.


Is sealer environmentally friendly?

By association – yes. Concrete is considered to be a component of green building as it lasts for a significant amount of time. As sealers help to extend that timeframe, they are considered beneficial to efforts of sustainability. 

The sealer itself, if water-based, is the most environmentally friendly; however, solvent-based sealers can be harmful to the environment. At Quickly Please Cleaning we always endeavour to use products that cause the least amount of environmental harm possible.
