How Long Does Limestone Sealer Last?

Limestone Sealer Last

“How long does limestone last?” is a question that I hear pretty often from consumers and home builders in the UK. It can be an expensive and challenging question to answer, as most limestone is produced naturally in harsh environments and has very little or no oxygen in the water. This is one of the reasons why limestone is not used for waterproofing, and it does not perform well in humid conditions. So, what can you do to ensure that your Limestone sealing Perth will last?

Type of limestone

The first thing to consider is the type of limestone being used. Different types of limestone have different properties, some more than others. For example, limestone formed in an alkaline environment (a lake, river, or stream) is weaker. It can absorb more than limestone formed in a more acidic environment (oceans, seas, or ponds). Another factor to consider is the weathering process that is taking place. Some sealers are more resistant to weathering than others, so it is always important to ask how long the sealer will last in direct sunlight and how long it will last in indirect light. Limestone is used to build walls, floors, and foundations in a lot of applications.

Installer or self-adhesive product

The next consideration is whether you want an installer or self-adhesive product. In my experience, it is better to use self-adhesive sealers because they are much easier to install. However, the trade-off with ease of installation is that they often require more maintenance on the homeowner’s part. Installing a self-adhesive product requires a cement mix that is more powerful than regular cement mixes. This usually means that the contractor must be contacted, and additional cement mix costs must be accounted for.

Advantages of sealer

There are also several advantages to having a sealer applied to a wall or floor. Limestone is recognized as one of the most resilient materials available for sealing and protecting buildings and homes. Limestone is impervious to moisture, sunlight, stains, cuts, heat, and humidity. The toughness of limestone is further enhanced by its natural color – which is generally white to translucent.

What do you need to know about sealing a surface with limestone?

So, one of the most important considerations is the type of limestone being used for the job. Specific forms of limestone are much more absorbent than others. For example, limestone sealed using a urethane coating is typically far more absorbent than uncoated limestone. Certain sealers also improve the absorption of other coatings. For example, limestone may be sealed using a moisture retainer.

Type of surface to be sealed

Another essential factor to consider is the type of surface to be sealed. If you are sealing flooring, for example, you have a couple of options. You can either use water-based penetrating sealers or water-based impregnating sealants.

Limestone sealers

Limestone sealers are generally recommended to be applied on concrete and stone. The reason for this is that these materials are porous and can easily absorb liquids. This absorption can occur even after the sealer has been applied, so applying the sealant right away is essential. As a general rule of thumb, the sealant should not be applied until the concrete has completely dried or once it has started to dry up.


In general, you will find that how long limestone sealer lasts depends on how it is applied. Applying a sealant as soon as the slab has completely set is generally recommended, so the final step is drying. Of course, Read more to know some cases where the sealer will have to be reapplied, significantly if it has been damaged or if water got into the sealing mix. However, this will depend on what exactly happened to the limestone.
