Hi gurus,

Can u skim coat yr exterior wall to make it smooth ? Or skim coat is only for internal wall only ?

Mix the skim coat with cement if you want it last long. Else the skim coat will fall off during rain

If I were to mix them, will it be long lasting ?

I hope you are not thinking of using the white stopping compound anywhere near the exterior. No matter mix with cement or not. Some half-past-six contractor / foreign worker told you can use?

Please use something like SikaWall^® 198 that is meant for external use. https://mys.sika.com/en/construction/plaste...nish2-in-1.html

Thanks for sharing. I didnt know this.

No worries, glad to share the info I had.

To be honest, skim coat is not an issue. Workmanship is the key.

I paid my contractor to do inside my house. After switching on my lights after dark, I was glad that I did not waste my money to do the external wall.

Some video clips show how the contractors in China do it nicely. But, honestly, few contractors in Malaysia have those equipment and I doubt their foreign workers could deliver the same effects.

I did explore various options available to do smooth external walls. Installing facade cladding probably is better. But, this is costly.

What is facade cladding ?

Stormer.lyn gave you the right URL search.

There are various types of materials to choose, Aluminum Composite Panel (ACP), Prefinished Fiber Cement Cladding, and etc

You don't have to paint, many design patterns, smooth and nice design. Most of the shopping centres are using this.

As for external skim coat, if your house is 2-storey and above, I don't think you will like the effects after paying the RM 4 - 6 psf for the work. Local renovation contractors just do not have the skills and workmanship. They just collect money from you and outsource to those foreign labour to carry out the work.

This is unfortunately so true. They don't even have the decency to at least be there and supervise the job anymore, but just let the worker do as they like as long as job completed.

External skim coat? Not common. Likely high end bungalows. Alternative is use the fine cement mix plaster. But need to use a good external sealer before painting. Else, paint on a smooth surface exposed to elements can peel easily.
