Epoxy Mortar Flooring Installation
Prepare the concrete
As with all our other epoxy services, we begin by inspecting and preparing the lowermost base layer of the system – the concrete. For epoxy mortar to adhere properly, the concrete base needs to be at least 28 days old and porous. We clean and dry the concrete floors thoroughly, making sure it is free of dust, oil, grease, and anything else that could interfere with the application of epoxy. We then test for moisture on the clean floors and if the result falls within the accepted range, we proceed with repairing any cracks in the concrete with our epoxy patching compound. This step ensures a clean and complete base layer for our epoxy mortar system.
Install a cove
Coves are important to install in industrial properties where we usually install epoxy mortar because it provides a smooth continuous surface from floor to wall, creating a tight seal for hygienic purposes. Generally, we install coves up to 6 inches high, but it can be customized to the desired height.
Apply primer
An epoxy primer is applied once the concrete is prepared. We use an epoxy primer that penetrates the surface of the concrete to make sure the concrete’s pores are filled in with durable epoxy primer. While the epoxy is still wet (but not puddling on the surface), we apply the mortar layer.
Apply mortar layer
We mix the mortar on site, mixing epoxy and our special sand aggregate together to form a thick and dense mortar layer. This is trowelled onto the wet primer to allow proper adhesion between the two layers. When it has completely dried and the epoxy underneath has cured, we sand and grind the surface to correct any imperfections.
Apply a seal coat
To make sure the mortar, epoxy, and concrete are locked in, we apply a seal coat on the floor and on the cove. This seal coat also serves as the first layer of pigment if you are looking to add color to your epoxy mortar floor.
