What’s happening in this video… Sealing concrete floors often involves more than just covering the flat concrete floor surface.

You must take into consideration the area where the floor and wall meet, especially if your floor receives any kind of water or liquid spillage on the floor.

To prevent water or liquid or foodstuffs getting in between the floor/wall joint, applying a cove up the wall is the best solution.

Applying a urethane cement cove in this food production room was the solution to prevent water leakage and bacteria build-up, thereby creating a “bathtub” effect in keeping this food production room contaminate-free.

Concrete Floor Sealer Questions…

Sealing a Concrete Floor – FAQ #4

What is bathtubbing a floor? What advantages does this process offer? And is a floor sealer worth the extra expense?

By “bathtubbing” a floor we are attempting to turn a room or rooms in a manufacturing or commercial facility into a bathtub formed at the perimeter of the room with 3 to 8 inch cove bases.

Just like the bathtub we have in our homes, water or other spills are expected to be contained within the area the cove exists.

Some people use a cove to go right up four inches. Some people use what they call a cant base that will go up two inches. Some people use a cove that will go up six inches. There are many different types of coving.

When you want to bathtub a floor, sometimes you might have an elevated slab upon a second or third or 27th floor, in a mechanical room.

You want to definitely bathtub and use coving because what you are creating is a watertight system. If you just terminate your urethane cement or your epoxy mortar right at the junction point where the floor meets the wall, you are leaving yourself open down the road for expansion and contraction resulting in a void between the floor and wall.

Any spills in areas not properly prepared with a bathtub will allow penetration of the spill through the wall and to floors below, if in a multi level structure.

The facility owner or manager should consider bathtub design in all areas where the walls and the slab create a separation or where the bathtub concept was not a part of the original plans for the building structure.

How To Fix A Floor/Wall Joint With A Waterproof Cove

These spaces will remain open unless something is done to fill them. You should definitely fill that void with a cove. And that cove is giving you a watertight area that will be much easier to clean and maintain in addition to preventing seepage through the area.

It’s also going to keep bacteria from harboring in these areas. In food processing facilities, owners and managers are keenly aware of this and always looking for areas where there is a void in the floor.

They don’t want to see a hole or crevice or joints falling apart. They know very well that wherever bacteria can grow, it will find that place and it will grow. So they are very concerned about this.

Bathtubbing the floor corrects the entire perimeter joint, fills it in, and goes right up the wall in a continuous seamless surface throughout the facility.
