Basic Chemical resistance of repair materials:

Call and talk to an expert when you’re planning your next coating project.

Your concrete isn’t just exposed to general wear and tear like a plant floor or warehouse. Your concrete takes a beating from steam, traffic, metal totes and the chemicals you’re processing. You need repair materials that can take it.

Here a few things to consider when planning your next repair project.

1. The chemical exposure

What is the predominant chemical or mix of chemicals that this area will have to stand up to? Your material will have to withstand exposure to these chemicals for a specified time.

2. Expected service for area

Is this area a secondary containment, loading area, storage, processing floor or something else? This will add the effects of temperature, traffic and abrasion to your list of things to consider.

3. Inside or outside

If your area is outside, you’ll need to choose a material that is resistant to ultraviolet light.

Here’s a basic guide to the types of chemical resistant repair materials and how they fit with

We all know that the key to the long term success of your joint sealant is it’s ability to stay bonded to the concrete sidewalls of the joint. But how do you make sure you have the best chance at superior bond in an existing joint. In one word, Prep. Preparation of the joint walls is critical and poor prep is a sure path to failure of the sealant.

Prep of your joints has to be done. And, the easier you make it, the better chance you have at success. There are many unique and high speed saws that are the latest and greatest for this job. But, you don’t have to break the bank to get it done. Chances are, you already have what you’ll need to clean and prep your joints. If you have a grinder, diamond blade, shroud and a vacuum, you have what you need.

Sealing joints in your concrete structures is key to prolonging the life of a concrete structures. Joints in slabs are critical for relieving stress to prevent cracking but they are also the weak point when it comes to traffic. Joints in containment structures are the main route liquids take to get to the ground. Not sealing these joints could lead to reportable leaks or even undermining of the structure if not addressed immediately.

Given that these joints are outside, there are a few things you need to know before you choose a sealant so you can be sure it will last.

1. Is the joint a control joint or an expansion joint?

They are very different when it comes to the range of movement they will see especially if they are exposed to direct sunlight. Control joints relieve stress in the adjacent slab sections while expansion joints allow room for each slab to expand without damaging adjacent slabs of other components of

SR Epoxy Sealer

Long Term Immersion (LTI): the coating will be immersed in the solution for extended periods of time.

Short Term Immersion (STI): the coating will be immersed for up to 72 hours.

Splash Zone (SZ): the coating will be exposed to the solution for only short periods of time before cleaning.

Rating:
R = Recommended for use.
N = Not recommended for use.

These recommendations are based on normal ambient temperatures of 65° – 85° F.

With the wide range of chemicals and compounds used in Chemical Production these days, there’s no way to use one product. You need to consider a few things before you decide what you’ll use.

1. What’s the basic chemistry of your product in this containment or production area?

Some coatings are designed for acid service while others are specifically for caustic. There are even choices for single common chemicals like sulfuric acid. This can be tough when a single containment is common to multiple processes.

2. Will there be an abrasion from traffic, dragging pallets, steel totes etc?

This is critical. You’ll have to make your system resistant to this if you expect it to last.

3. What will the temperatures of the materials be?

You need to make sure the coating can take it or make other arrangements to allow for cooling prior to contacting the coating.

Re-coating a secondary containment area seems to be pretty easy. I mean, it’s just paint right? Well, it may brush or roll on like paint, but chemical resistant coatings are much more. Before you jump into self-performing a coating like this, you need to consider that you might need a contractor. Here’s some things to think about.

1. What’s the level of difficulty?

If this going to be a simple re-application of primer and topcoat you should consider doing it yourself. Of course, there will be some prep required. But it should be easily done with the tools you have with some direction.

If the system is new and will require reinforcement at joints and transitions, you might want to get a professional to look at it.

You could probably self-perform if a grout type system is to be used if you have people that have poured grout or done general concrete repair.

However, if it is a troweled down system with reinforcement, you should get a contractor
