How to Add Cement over a Brick Chimney How to Add Cement over a Brick Chimney
While adding cement over a brick chimney is not the easiest diy task to accomplish, these steps will help you complete the project finished in a day.
Step 1 - Mist the Brick
Using the plant mister and water, mist the surface of the brick that you want to put cement over. Make sure that you aren't drowning the brick with water, you just want to make it moist.
Step 2 - Mix Cement
Follow the directions on the cement and mix it in the bucket. Typically you will want to have a 3 to 1 ratio. The consistency should be like cake batter and pretty easily stirred.
Step 3 - Add Concrete
Using the trowel you can slowly add the concrete onto the brick chimney. The best way to do this is in arcs. The key to this step is to make sure that the brick does not dry before you add on the concrete. So if you get to a section that has already dried before you could get to it, you will want to moisten it again with the mister. Using the magnesium float you can smooth out the concrete as you go. Once in a while make sure to dip the float in water. This will help to keep the concrete from drying while you are working and bunching up. Before you continue to add cement, check to make sure that the water is just misting and not completely dripping as this will cause bumps in the concrete as you go.
Step 4 - Keep Misting
The key to this project is to keep misting throughout each step. You want to make sure that you are keeping it wet enough to bond the cement and the brick together but not too wet that it will slip off. Once you have actually finished laying to concrete and smoothing it out to your liking you will want to mist only about every 20 to 25 minutes. You will have to keep an eye on it and do this misting on a schedule until the concrete is completely dried. Watch the concrete carefully to make sure that there is no sliding or slipping and that everything is just in place as you want it. If something needs to be fixed, this is the time to do it. While this does sound like a hassle because misting will slow down the process a lot, it will help to effectively bond the cement with the brick and ensure that it is strong and lasting.
Once you are finished with these steps and the concrete has dried you will want to keep off of it and make sure it stays untouched for 48 to 72 hours so that it is allowed to sit. Afterward you are done with the project and should give yourself a pat on the back for all of your hard work and patience.
