Quikcrete Mortar Mix For Stucco Base Coat
Hello to all. I just put a base coat of Quikcrete mortar mix on some exterior block walls around my house. They have been sitting for some years and never finished them. I pressure washed them and hit them with a muriatic acid solution first. I did not realize the mortar is type n, should of used type s or m or do you think i will be alright? Going to put California stucco over it. Still have some to do. Any Suggestions will Help! Thanks Poppy

Ha, google is my friend.
I thought it was a specific style, not a brand. If it is an EIFS finish coat you will probably be fine. I have that stuff on some clothes still from about 6 years ago, the pants are worn down to nothing and the EIFS is still brand new looking, tough stuff. |

No worries, but next time add some fibermesh and latex bonding adhesive.

Re: Quikcrete Mortar Mix For Stucco Base Coat
Around here something such as Western One Coat should have been used. It has the fiber mesh that Tscarborough mentioned.

Re: Quikcrete Mortar Mix For Stucco Base Coat
On the the north side of my front stairs where there was some mold before I cleaned it I brushed on Stuccobond diluted 50/50. I tried chipping away some on that wall and another that I didn't use bonding agent and seems to be well adhered. The one wall left on main house do you guys think I should use type S mortar or am I worrying for no reason? I may also want to switch to Sonewall acrylic stucco but someone told me it might be a problem over mortar with lime. Also can go over 20 year old standard stucco with the Sonnewall after pressure washing it?

Re: Quikcrete Mortar Mix For Stucco Base Coat
For stucco, Type S or N is really a meaningless standard. How much compressive strength do you think you need? Is like Superman pressing against the wall?
For stucco, you want flexural strength and minimal plastic shrinkage, so a high lime, fiber reinforced mix is best. |

Re: Quikcrete Mortar Mix For Stucco Base Coat
Just out of curiousity who advised you to use either type n or type s mortar as base coat for EIFS?
I have never heard of this being done so I cant speculate. If you are planning to do regular stucco I do not get why would you want mortar instead of portland mix? You are going to have headache with brushing/rolling bonding agent on(waste of time). If you are planning to do EIFS why not to just get regular base coat for acrylic? |

Re: Quikcrete Mortar Mix For Stucco Base Coat
Not knowing anyone to ask and always relying on myself I usually do the right thing. Unfortunately not having enough experience and being in a hurry this is what I did. It may not be right but if it will do the job I will be happy and learn from my mistake. Twenty years ago when the house was built I mixed from scratch sand, couple of shovels of lime and maybe 15-20 shovel of sand for base coat and lasted excellent. Life hit and never finished. I don't know that's why I'm here!

California Stucco doesnt require anything underneath it. It is the god of stucco. Scrape it off and put the CS directly on the block.

Re: Quikcrete Mortar Mix For Stucco Base Coat
Yeah its made by Silpro. Very similar to Utrowel by Umaco. I labored on a block wall on a garage that was stuccoed with this stuff in 1986. It looks pretty much exactly as it did when I was sponging it. I also did a block retaining wall at my parents house when I was 20, 21 years ago. Looks exactly the same as the day I finished it, save some dirt on it.
