Steps On Pouring Concrete Around Toilet Flange

1. Wipe The Toilet Flange

When pouring concrete around a toilet flange, you will want to prep the flange beforehand.

In most cases, it’s going to be messy and that’s common when looking into the drain. Due to this, you will want to find a way to remove the debris and get a clearer view of what is going on with the flange.

To do this, you can use a vacuum and a clean cloth.

This will allow you to get rid of the debris while also making sure you wipe away any residue that is present around the flange.

Take your time doing this and make sure the flange is fully prepped for the next steps.

2. Apply Putty Around And On The Toilet Flange

Now, you are going to focus on the toilet flange.

The idea here is to take the waterproof putty and begin applying it to the flange bolt holes and screw holes.

You will want to ensure they are appropriately covered.

This is to ensure they are protected when you are pouring concrete and it’s easy to complete the installation when everything is in place.

A lot of work goes into this, so you will want to get it right.

Be methodical and apply the putty in the right spots to ensure you have enough space to pour the concrete around the toilet flange.

3. Let It Dry

When you are done applying the putty, you can then move forward with the drying phase.

This entails letting the putty dry carefully and making sure it settles onto the flange bolt holes and screw holes.

How long is this going to take?

It will depend on the situation and the environmental conditions in your bathroom. For the most part, if it is room temperature in the bathroom, it is going to take 30-60 minutes to dry.

Just let it settle and then you can begin working on pouring the concrete near the toilet flange.

4. Pour Concrete Around The Flange

You will want to complete the process with concrete.

When you are doing this, it is highly recommended to put some form of protection around the top of the flange to make sure nothing goes in.

This will also ensure it works as planned and the concrete only goes where it is supposed to.

If you leave the hole uncovered, it will get to the stage where you will have to be pinpoint accurate with how the concrete is poured.

Don’t take a risk and make sure to have something on top of the toilet flange while doing this.

Final Thoughts

When it comes to pouring concrete around the toilet flange, these steps will help ensure things work out as planned.

When pouring concrete around the toilet flange, start by wiping the flange using a dry cloth to remove debris or residue. Now, use industry-grade putty to cover the flange bolt holes and screw holes. Now, begin pouring the concrete where it needs to go while covering the hole.

This will ensure the concrete goes where it needs to and everything works out as required.

This process is going to take a bit of time, but you need to make sure those bolt and screw holes are not covered with concrete.

Since the concrete has to go after, you will need to be diligent with the steps mentioned here.

Go through them one by one and make sure the key holes are covered.
