use a professional installation service?

While you may be able to find tutorial videos on how to install these types of floor coatings all over the internet, installing a liquid floor coating yourself is risky and requires a lot of preparation. If you overlook one step you will unfortunately find yourself back to square one and need to completely re-do the coating. This is why it is always recommended to use a profesional installation service to avoid these unexpected issues that often occur during the installation of an epoxy or polyurethane coating. 

The most common problems encountered when installing an epoxy or polyurethane coating without resorting to a professional installation service

Problem no 1

Surface condition before the installation

To successfully install an epoxy or polyurethane floor, it is essential to properly prepare the surface beforehand. Here are a few key points to keep in mind: 

Porous concrete: A porous substrate can lead to bubbles in the flooring during installation. Very porous concrete can even crack or split under your new resin floor. Remember, a new epoxy coating will not improve the condition of the concrete it covers. When in doubt, apply two coats of primer. 

Surface Preparation: Mechanical concrete preparation is required prior to installation. It is preferable to use tools such as a grinder, shot blaster or scarifier to obtain a binding profile that matches the system that will be applied. Before proceeding to the next step, remove all traces of laitance, oil, glue, etc. If in doubt, apply two coats of primer. This step is key to the success and durability of your project.

Problem no 2

The installation environment and curing

Once you are confident that the surface on which you will apply your new flooring meets the requirements, there are a few things you should check before, during and after the installation of the liquid floor. Here are some examples: 

Cleaning and blocking access: From the beginning to the end of its installation and curing, your flooring will be exposed to the environment. You must make sure to remove all dust from the surrounding area (floor, walls, other surfaces), close all openings through which insects could enter, and do note hesitate to close or even lock your doors to prevent someone from accidentally entering the area during the curing process.

Temperature: The different resins used for liquid floors are very reactive to temperature. Refer to the installation instructions for the ideal installation temperature (usually 20 degrees Celsius ±). In general, the warmer the temperature, the faster the curing time. For example, in a very hot environment, the installation time can take as little as 5 minutes! IMPORTANT: Several hours before opening the products, make sure to let it rest at the required temperature. 

Humidity: High humidity could cause the products to react during curing and leave undesired marks on the final product.  Controlling the ambient humidity level will help you install your new floor successfully.

Applying an epoxy or polyurethane coating requires some preparation. You must follow the instructions on your chosen product to ensure a successful installation. 

Installation time: Each product offers a favorable installation time, depending on the ideal temperature. It is important to respect and plan the installation according to these factors, otherwise you may find yourself  with undesired effects such as bubbles or visible roller bumps after curing.

Condition of the previous layer: Your new flooring will be installed in several layers. Normally there is a primer, grout, top coat and sealer. (We suggest a minimum of three coats). If the previous coat is not fully cured, do not apply the next coat! A coat that is not yet cured will still be wet and sticky.

Product Mixing: Liquid floor coatings come mostly in two components. Component A: a resin, and component B: a hardener. In some cases, a component C is necessary if there is an added aggregate or silica in the mixing. A specific mix exists for each product. Be sure to follow the instructions for a successful installation. Too much component B (or the opposite) may lead to a coat that will not cure.The end result is an undesirable aesthetic finish.

Floor joints: Specific products exist to fill or create floor joints. Ask your retailer about the products needed when installing a liquid floor. The use of a window or bath sealant, for example, may not be compatible with your new flooring. 

By keeping an eye on the factors mentioned in this article, with the right products (essential) and with the proper tools, you will be able to get started on your project and install new resin floor coatings.
