Old paint is subject to deteriorate and turn to chalk - a fresh coating isn't apt to adhere to chalk long term.To just change the color, I'd pressure wash first, check to see if there is any chalk left [if there is add Flood's EmulsaBond to the 1st coat of latex] and paint when dry. An elastomeric paint will soften the texture some but to completely change the texture it need to be re stucco'd. You'd either need to remove the existing paint or apply a bonding agent first.
Change painted stucco texture/color
Hello,
I am looking for some advice on a stucco project. Currently my house has a rough-textured stucco exterior which has been painted (I can tell because it is quite old and some paint has already flaked off). See attached picture.
I'm not a fan of the rough texture. What I would like to do is smooth it out quite a bit and have it be white (so it would look kind of old world mission style with an imperfect smooth finish).
I'm new to this, and I know it is not the easiest DIY project, but I would like to learn how it can be done. I'm assuming that I need to remove the paint first. What would be the best way to do this? Could I then apply stucco on top of the old stucco? I found a product called LaHabra Santa Barbara Mission Finish (see attachment) which looks ideal because I wouldn't even need to paint it, although it looks like I would need to apply a stucco base coat first.
I would appreciate your thoughts. Thank you!

To change that texture I would do it in the following way.
(1) Using an Angle Plane knock off the high areas. ( see KraftTool.com )
(2) Pressure wash to remove all loose material.
The following are just material I would use you can cross reference to your choice.
(3) STO Plex W surface conditioner.
(4) STO RFP Base Coating.
(5) Select a STO Finish like one of the following StoSilco Lit., StoSilco Flex or STO free Stile finish.
All the above finish's come in the color you select.
All the above materials are Synthetic.
The RFP base material will bridge cracks & provide a water proofing to the exterior.
As for the Lahabra product you ask about it is a Stucco cement product & I would not advise it be used over existing Stucco that has a painted surface unless you can remove all the paint. Lahabra has the Synthetic coatings you can change the STO for their matching product.

Thanks very much for the advice. I hadn't considered elastomeric paint - I'll take a look!
Hi Clarence,
Thank you very much for the great advice. I didn't know that there are two types of stucco: synthetic and traditional (cement). I've done some reading on this now. Since my stucco is painted, you are saying that I would only be able to install synthetic stucco over the existing stucco because traditional cement-based stucco would not adhere well to the existing painted stucco that is already there.
If I have that right, I just have a few follow up questions if you don't mind:
1. The purpose of using the angle plane is just to remove some of the texture, right? There will undoubtedly be some paint left afterwards (in the surfaces that are underneath the textured parts). The STO Plex W surface conditioner would still be okay to use on this surface if there is still some residual bound paint?
2. If I understand you correctly, I use the angle plane to remove texture, then apply the STO Plex W surface conditioner, then the RFP base coating, and then an acrylic finish of my choice? I was just looking the the Lahabra acrylic finishes (I'm looking for a smooth finish) and I see two types of acrylic finishes:
a) "Perma-Flex Stucco Grade Acrylic Finish" which is described as "a 100% acrylic-based textured finish for stucco only", and
b) "Perma-Finish EIFS & Stucco Acrylic Finish"
I'm assuming that I can't use the first one (stucco grade acrylic finish) since the RFP base coat that I would be applying it to is synthetic stucco rather than traditional stucco, or am I wrong? If so, how would I choose between the two types of finish?
Thanks so much!

Yes the angle plane will knock off the high areas. You would than pressure wash after the use of the angle plane to remove all loose material.Hi Clarence,

That the STO Plex-W.
The RFP is an Acrylic Base Coat material that will adhere to any paint that remains.
I would not recommend the use of Perma-Flex Stucco coating.
When using the Synthetic Base stick with the Acrylic EIFS / Stucco finishes.
Yes you are correct a Cement based Stucco will not adhere to paint very well plus Cement Stucco applied over Existing Cement Stucco will delaminate over a long period of time.
You can get many textures using the synthetic system if you use the STO Lit Freeform applied over a sand finish you will get a Limestone look.
You should call STO Corp Atlanta,GA. 404-346-3666 or Toll free 1-800-221-2397 & explain what I recommended they may give you some other advice it is free info. Also ask for a sample of the products that you select & if you want to make samples ask for wet sample material.

If you call STO Corp. ask them if you can use the STO Gold Coat which is a water proofing material that apply the STO BTSB base coat material to level out, than apply the STO Synthetic coating of your choice.
Thank you so much for all the information, I really appreciate it. It’s going to take me a while to get this started but at least I understand the scope of the project a lot better now. Thanks again!!

paint = 'colorcoat ' - sher-wms calls it loxon as i recall
Loxon is a line of masonry coatings by SWP. Before it came out I painted miles of stucco with latex house paint, either will give a decent job.
interesting - we don't repair much stucco anymore but nevertheless a good tip,,, thanks, m
