Pre Slope Bed Vs Sloped Mud Floor

The most common method for constructing a pre slope is with a mixed cement and sand deck mud that has a consistency that will allow it to be balled up in the palm in your hand.

Pre slope bed vs sloped mud floor.

Finally a mud bed more easily allows for customization as opposed to a preform that must align with the existing shower and drain layout. It is for all types of paver tile and marble installations on floors and counter tops. Using a trowel a 2 4 wood piece or even a level you can pack the deck mud up to the desired height all around the shower pan. The overall thickness of the mortar depends on a variety of factors.

If you are using a preformed shower pan the manufacturer of the pan should provide instructions as to how thick the mortar bed needs to be. I try to make my pre sloped the proper thickness at the drain so it will be 1 1 2 at the walls. In addition a higher skill level is needed to install a consistent and necessary slope towards the drain. Under that slope is the pvc liner which is on top of your preslope.

The setting bed on top on the other hand must be consistently at least 1 1 4 to 1 1 2 thick everywhere follows the slope of the bottom layer and thus sloped. The perfect pitch stuff is not really your friend it leaves a weak spot in the mudbed. Start with a solid clean and properly supported shower floor. Deck mud is a mixture of washed graded sand and portland cement that conforms to astm c 144.

Your finished flooring after your liner and leading mud bed are set up requires to be 1 to 1 1 4 thick at the drain. However using a mud bed is usually a longer installation process than using pre constructed kits. If we make the pre incline 3 4 thick at the drain it requires to be a total of 1 1 2 inch thick at all your walls. Seriously if you ve got water getting under all that tile and cement and pvc lining you ve got bigger issues than a little preslope.
