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!
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.
