Hi muriqi1962,


Thank you for your question and welcome to our community. 


The first process you will want to accomplish before you put the stucco onto your cider block wall will be to clean the area with a pressure washer.  Once the area has been cleaned, you will want to apply  a bonding agent over the clean cinder block. Use a paint brush or spray gun to apply the bonding agent.


Allow the bonding agent to dry.  Apply your scratch coat using a hawk (a flat tray with a handle).  Place your hawk against the cinder block wall and spread the stucco onto the wall using a flat finishing trowel.  Press the stucco scratch coat against the wall at about ¼ inch thick.  Use enough force to press the stucco into the pores of the cinder block.  The will help to create a stronger bond onto the cinder block.

Allow the scratch coat to dry for about 3-4 hours.  Before you use your stucco rake, apply duct tape about ¼ inch below the top tines to prevent the rake from going to deeply into your scratch coat.

Allow the scratch coat to dry for 2-3 days. Keep the scratch coat damp by misting the scratch coat several times a day.  This will help to prevent cracking of the scratch coat.   


The next step will be to apply your colored stucco coat.  Use the hawk and your flat trowel to apply the stucco coat.  Apply about ¼ inch of the stucco over the scratch coat.  Be sure to coat the entire wall evenly.  You can smooth the corners using a paint brush.  Apply a pattern if you wish using a trowel, float or a brush or broom.  



Once the stucco has been applied and the pattern set, mist the final stucco coat several times a day during its curing.  Curing should take place in 2-3 days, depending on your location.  


Be sure to take a video of your stucco project and share it with the rest of the community in our Project Library under "I Did This".


Please let us know if you have any further questions.


This has been another of,
