Different Types of Concrete Sealers

Whether you are building an apartment, bungalow, or a multinational corporation, the need for waterproofing can knock on your customer’s door at any point in time. When it does, it is an absolute nightmare. And people who have dealt with post-construction waterproofing issues have nobody but you to blame for it.

Fortunately, we live in a world where concrete sealers are saviors of leaking and damp structures. Concrete sealers help you restore the strength of your structures by covering the pores of the surfaces and making them water-resistant.

You are even luckier if your structure is still under construction because you have the opportunity to start right and avoid thousands of dollars’ worth of damage to your customers in the long run.

Types of Concrete Sealers

While there is an abundance in the variety of concrete sealers in the market, here are the five major concrete sealers that are commonly used for waterproofing surfaces.

1. Penetrating concrete sealers

Penetrating concrete sealers are popularly used by both individuals and companies for waterproofing their structures and surfaces. They seep into the pores of the surfaces to protect them against pressures and harsh weather.

This type of concrete sealer stays put even in extreme conditions and do not slip when met with anything too cold or wet.

2. Colored concrete sealers

If you wish to build strong yet beautiful projects without doubling the costs, you might want to give colored concrete sealers a try.

Colored concrete sealers can have a satin finish on interior floors and are highly pigmented, so one application is enough to alter the appearance of your structures. They are incredibly popular among companies who prefer building aesthetically pleasing modeled surfaces over solid matte ones.

3. High and Low Gloss Sealers

High and low gloss concrete sealers are multipurpose sealers that can be used for interiors as well as exteriors. Depending on your customers’ preferences, you can opt for a gloss sealer that will not only protect and make them water-resistant but also offer a gorgeous sheen to your surfaces.

If you are looking for something to brighten up your structures, high and low gloss sealers might be for you. And while they are a tad on the pricier side, their performance is unparalleled.

4. Acrylic Concrete Sealers

Protecting the homes and other surfaces that you have created so skillfully doesn’t necessarily have to strip you off of your entire budget. Acrylic concrete sealers allow you to brighten up your surfaces while keeping your costs down.

You can buy acrylic concrete sealers in various levels of sheen and formulation types. They are easy to apply and do a brilliant job of protecting your surfaces against humidity and dampness by forming a shielding film around them.

Luckily, offering the best to your customers isn’t challenging anymore.

5. Polyurethane Concrete Sealers

Just like acrylic, polyurethane concrete sealers save your structures by forming a protective layer over them. This layer, however, is stronger than the one offered by acrylic sealers.

Polyurethane sealers perform optimally on high-traffic surfaces. Therefore, they are perfect for big offices and companies that experience high footfall throughout the day.

How to Choose the Best Concrete Sealer

The sealers’ market is a daunting place. There are so many options in the market - each claiming to be better than the other - that when you contemplate your options, you end up buying the one that you think is the right choice, but is the one that is more profitable to your supplier.

So, what should you consider when buying concrete sealers?


When you are a construction firm, waterproofing is an unavoidable and expensive expenditure for you. So, choosing an affordable concrete sealer is crucial. Generally, a good quality penetrating concrete sealer will cost you less than any other due to its ability to easily smear over the surface. This helps you wisely utilize every container to its last drop.

Besides, instead of going for multiple smaller units, buying concrete sealers in bulk allows you to save big as you tend to save more when you make one-time purchases.


Before you order concrete sealers for your company, ask yourself how much of it you need exactly. Depending upon the quality of the concrete sealer and the scale of your project, you must correctly calculate the required quantity of the product. 


It pays to be responsible and safe in today’s world.

Usually, concrete sealers have higher VOC (Volatile Organic Compounds), which is deemed extremely hazardous. When buying a concrete sealer for your projects, ensure your product has low VOC. It is even better if you can get your hands on a Green Listed sealer such as this penetrating concrete sealer.

More often than not, concrete sealers are toxic. They can also induce breathing difficult, so you must provide your customers with the best living environment.

Eco-friendly concrete sealers are non-toxic, non-flammable and non-caustic. So, if you decide to opt for a healthy and environmentally safe concrete sealer, this is a no-brainer.

Number of Applications

Most newly established construction companies end up buying cheap concrete sealers to bring down construction costs.  But many cheaper sealers require several applications to work properly thus costing you more in the long run.

On the contrary, high-quality concrete sealers might appear to be relatively heavier on your firm’s balance sheet but will do the trick with just a single application.


The last item on your checklist when buying concrete sealers should be the longevity of the product.

Brands like Trojan Masonry & Concrete Sealers actually offer a 15-year waterproofing warranty on concrete sealers, making them one of the best in the market. Additionally, they are environment-friendly.

Therefore, you really get to enjoy the best of both worlds.
