Well, it’s better if you use a self-leveling compound on a hardibacker. This is because this compound works great over one. The mixture of the compound will blend with the hardibacker.
Many people ask – do I need primer for self-leveling compound?
Well, you won’t have to use any primer because of the blended mixture of the compound to your floor. And, if you still want to use any primers, use spray paint to apply them. However, don’t use multiple buckets on it. Just use some at a time and that’ll do the trick.
In the end, you must seal off all the points. This is because the compound can pour over to any of the little holes in your floor. So, it’s better to seal off any points if you don’t want this compound to reach it.
How to Use Self-Leveling Compound over a Hardibacker?
By now, you’ll know almost everything about the self-leveling compound. So, you can just pour them on your floor and hope for the best, right? But wait, hear me out. It isn’t as easy as it sounds.
Moreover, you can mess up things quickly if you don’t have a plan. Even the most straightforward work like mixing can go wrong if you don’t do them correctly. Just like this, a lot of things can go wrong.
But wait, we’ve got your back. In fact, in this article, we’ve shown exactly how to install a self-leveling compound. We’ll even show the preparations you should. So, let’s not waste any more time and get right into it.
Yes, you’ll need a set of tools for the job. However, all of them are available and affordable. So, you can purchase them from a local store at a reasonable price:
- Floor cleaner
- Spray bottle
After you’re done managing the tools and making all the preparations, let’s start:
Step 1: Prepare the Surface
So, how to prep floor for self-leveling compound? Well, the hardibacker board should be stable before you apply the mixture. If the surface isn’t stable, it’ll move throughout the process.
On the other hand, before starting, make sure that the surface is clean. This is because you want to apply the compound away from dust and debris. So, clean the floor using a floor cleaner.
Step 2: Apply Primer
Even though we’ve discussed that a primer isn’t needed, you should use it over a hardibacker. Hence, take a spray bottle and spray a bit of primer over the board.
Here, make sure the primer is dry before applying the compound. Because, if the primer isn’t dry, it’ll react with the compound. Make sure there’s enough air in the room after you apply the primer.
As a result, the drying process will be faster, and any type of unpleasant odor will eliminate quickly.
Step 3: Marks The Uneven Positions & Prepare The Compound
Firstly, mark all the uneven points over the board. Even though a hardibacker board is leveled, it can have rough spots over time. So, identify them and mark them.
After this, start preparing the compound. This is because this compound dries very fast. And so, you’ll have to finish the process quickly. That being said, start following the user manual to mix and apply the compound.
Wear your protective gear and start mixing the compound with water. Here, it’s better if you use cold water. Also, remember to use less water.
Step 4: Apply the Compound
Spread the compound, as discussed before. Here, you should apply them to the uneven areas. After the compound thickens, start using drywall to level them.
You shouldn’t use any more water or heat on the hardibacker board. This is because it’ll slow down the process of drying, and the compound won’t be stable. After you’re done applying it, the compound will dry out within 4-5hours.
Step 5: Clean Everything
Well, this is a no-brainer. You’ll have to clean it after you’re done. Clean the areas with a cleaner.
Also, don’t forget about the tools that you’ve used. Clean them with warm water. And, if they don’t clean thoroughly, separate them. This means you’ll use these tools only when you’re using a self-leveling compound.
