Reasons to Cover Asbestos Siding
Asbestos is a harmful component and can be very perilous. It consists of very small particles which can actually harm people’s health. Even in many states, there are specific rules for using asbestos siding.
If your building has old asbestos siding, cover it with stucco. It’ll give you a smooth finish. Its hazardous effects will be lessened as well.
There can be two probable reasons for covering the siding. The first one is old sidings make your house look dull from the outside. The second one is just to hide the asbestos siding by a top coating with something like stucco.
In case you’re planning to cover the siding because they’re old. Then you can also remove the old asbestos siding and install new ones. Another thing that you can do is installing another siding on the existing asbestos siding. Then cover it with the stucco or you can install the stucco directly.
Coating the Siding with Stucco - 4 Steps to Follow
Now we have come to the most important part of our work. We need to follow certain steps one after another. Now there’s one thing you should keep in mind before starting. So, here it goes-
Considering the Weather Conditions
Working with stucco involves cement-based material. So being considerate about the weather is really important. You can use the temperature scale and humidity counter for this purpose.
Starting work on a rainy or humid day can ruin the project. You better choose an overcast day with low wind. The optimum temperature is 10-16 degrees centigrade.
It’s best to do the installation during winter. So keeping that in mind, let’s move forward.
Step 1: Arranging all the Necessary Instruments
At first, you need to arrange all the necessary instruments and put them together. We have made a list of items that you will need:
- Bonding agents (Plaster sand)
- Metal and plastic cutter
- Trowel or similar spreading tool
- A large bucket to mix the ingredients
You’re completely prepared with the equipment now. So let’s jump to our next step.
Step 2: Check the Condition of Asbestos Siding
Asbestos siding is a complex thing to work with. Nailing this type of siding is also a tough process. So you need to take care of a few things before starting.
Firstly, you need to make sure the siding is in good condition. So, you should search for any cracks or fissures in the siding. If the siding isn’t properly set, you can’t put the stucco on it correctly.
Your only other option is to completely remove the siding or put new siding on top. Then you could go about installing stucco at the end.
Step 3: Making the Stucco Mix
You need to mix the ingredients in the proper amount. An optimum recipe needs 1 part of cement materials and 2.5-4 parts of plaster sand. Then mix them with potable water to make the scratch coat.
The cement that you’ll use in installing stucco needs to be clean and well graded.
Hopefully, now it’ll be easier for you to get the best cement.
If you aren’t comfortable with making your own mix, just buy one. It must be a bit tough for you to choose one. Don’t worry, friend. Here’s our recommendation list to lessen your tension:
Finally, you’ll have your stucco mix. That too without the hassle of measuring so many ingredients.
Step 4: Layering on The Stucco
Now it’s time to spread the mixture on the siding with the trowel. You might be wondering which type of trowels will be perfect for this purpose.
A large variety does exist, so we’ve tried to make it easier for you. Here are some of our best picks of trowels that’d just go fine for this project:
Now take your trowel and start spreading the mixture.
The first layer of stucco needs to be at least 9.5 mm thick. This layer is called a scratch coat which needs at least 48 hours to cure.
If your relative humidity isn’t 70%, then you need to mist or fog it daily. You can also use a rotating lawn sprinkler to keep the layer damp.
For the brown coat, you need to mix 1 part cement with 3-5 parts of sand. This layer will also be 9.5mm thick. So the total thickness will be 19 mm.
It needs 7 days to get cured. But the first 48 hours are the most important. So you better keep fogging at least for the first 48 hours.
Now is the time to put on the final coat. Which needs 1 part cement with 1.5-3 parts of sand. It should be 3 mm thick. As it’ll determine the outer surface, be very careful while spreading it.
This layer also needs at least a week to cure. After this, you’re all done with covering the siding with stucco.
Once the stucco is dried, you can either color it or leave it as is. Whichever you prefer!
Necessary Concerns When Working With Asbestos
Asbestos sidings are made of fine asbestos fibers which can be really harmful. So working with asbestos siding can be as dangerous as cutting them.
Asbestos can cause pleurisy, pleural infections and plaques, and even COPD. So you need to wear proper respiratory protection. If possible, try not to touch the siding directly.
We already mentioned that there are specific rules for different areas. Gather the necessary information about your native area’s disposal rules.
In certain towns, you need to bubble bag the asbestos wastage. And dump them into a hazardous waste dump. Maintain this with utmost care. As keeping them around your house won’t be a wise choice.
Question: Can you cover over asbestos siding?
Answer: Yes, you can cover asbestos siding with other types of sidings. For example, you can use vinyl sidings on top of them.
Question: Can you stucco over siding?

Question: Can you remove siding and replace with stucco?
Answer: Obviously, you can. You can remove your asbestos or vinyl siding. Then put the stucco on the wall.
That’s all you need to know before covering asbestos siding with stucco. Hopefully, you’ve realized how the whole thing should be done.
Hope your experience went smoothly. And lastly, best of luck with your covering asbestos mission.
