How To Stop Concrete Staining

Concrete is a popular building material that is known for its strength and durability. However, one of the common issues that can arise with concrete is rust stains.

These unsightly stains can make your concrete surfaces look old and worn out. In this article, we will explore why concrete gets rust stains and what can be done to prevent them.

First, it is important to understand what causes rust stains on concrete.

First, it is important to understand what causes rust stains on concrete. Rust stains occur when metal objects that come into contact with concrete begin to corrode. This corrosion releases iron oxide, which is the primary component of rust. When this iron oxide comes into contact with the concrete surface, it can cause a reddish-brown discoloration, commonly referred to as rust stains.

So, what causes metal objects to corrode when they come into contact with concrete?

The answer lies in the chemical makeup of concrete. Concrete is an alkaline substance, which means that it has a high pH level. When metal objects come into contact with alkaline substances, it can cause a reaction that leads to corrosion.

Another factor that can contribute to rust stains on concrete is water.

When metal objects are exposed to water, it can accelerate the corrosion process. This is because water can increase the alkalinity of the concrete, making it more likely that a chemical reaction will occur. Now that we understand the causes of rust stains on concrete, what can be done to prevent them? One solution is to avoid placing metal objects directly on concrete surfaces. This can be accomplished by using rubber mats or other materials to cushion the metal object and prevent it from coming into direct contact with the concrete.

Another solution is to apply a sealant to the concrete surface.

Sealants can create a barrier between the concrete and any metal objects that come into contact with it, reducing the likelihood of a chemical reaction occurring. However, it is important to note that sealants will need to be reapplied periodically to maintain their effectiveness.

The RexShield family of sealers is uniquely suited to stopping rust stains on concrete

Available in gloss, satin and matte finishes RexPro’s 2 and 3 part sealing systems stop rust in addition to other corrosive and staining agents including acids, oils, acetone and more. Unlike most sealers, RexShield does not create a thick plastic-like film on the surface of the concrete. It both penetrates into the concrete and grows a thin crystalline layer on its surface. This makes the concrete harder, more resistant to abrasion and stops rust in its tracks.
