How to shoot a fog coat over an existing colored stucco finish
Howdy guys and gals, I have had many e-mails asking how to apply a fog coat, so I promised I would show how I do it in this easy to understand step by step video, For you folks who like to do it yourselves.Fog coating is mainly used on say large wall where lots of fellas are spreading color finishes on different levels, many times the scaffold joints will show. (Different suctions on the wall), weather, heat, and especially water play an important part in color uniformity, not to mention many guys simply working and not paying attention to teamwork.
The other time is for a similar purpose, say for example a wall was too wet in certain areas and really dry in others and the person in charge did not mist is uniformly, nor did he understand all the natural effects in play.
(Happens to all plastering fellas a time or two before learning begins))
The main method of application when fog coating is, spray a maximum of two or possible three separate fog coats as this is usually the most a wall can absorb of colored stucco water, or you may get a powdery residue. If you spray one fat coat a powdery residue will often remain also. What’s the big deal about this remaining residue?
You can use you hand to swipe it or the first rain can easily wash it off. These instructions are just the tip of the iceberg as far as knowing how to fog coat. There is still much to know, not mentioned here.
Anybody that wises to learn how to do anything with stucco e-mails me and when the opportunity arises I will do it as for your benefits or explanation purposes. Plus it gives me something to do.

How to shoot a fog coat over an existing colored stucco finish

Hey Guy, work in the Bay Area is still very slow; 4 years of recession has put a hurting on contractors in every field. The fellas who are still working today are the ones who usually are referrals from previous customers. These are the guys, who have developed the habit of going the extra mile, are knowledgeable, fair priced and have a good attitude towards work and life. This is my personal opinion.
Best wishes, with you plastering business.

Hi Kirk, If i have a scaffolding joint ,only on one Wall do i have to still Fog Coat the Wholw House?
Howdy RMA, No. You only have to fog the wall with the scaffold joints. Make certain your tip is new and not one grain of sand is in your tank. One grain will clog the tip and instead of a mist shoot a solid line which will mess up the wall. Fog coating really takes preparation, also. Cover all windows & doors. Lastly a light fog about 3 times verses one thick coat is the best method.
Best wishes

Very interesting, thanks for posting this video!
Hello and thanks for the bone, Jason and I are always welcome to share the plastering knowledge.
Have a good evening!

Howdy Gordo, If their house is paint now use paint to darken. If they have a cementitious maintenance free free color finish than you can darken it a small bit with a fog coat but, it’s preferable to simple apply another color coat directly over the existing finish. Of course there is prep work before this can be done.
Best wishes, and have a groovy day!

Hello, my stucco finish appears blotchy after being stucco'd 6 months ago, especially around windows that were previously painted before the stucco. Is this normal? Can it be fixed? Thanks
Thank you Kirk for taking the time to share your experiences on your videos for all of us do it yourselfers. I just finished stuccoing a 250 ft cinder block area which turned out really well but there was some color variances with the final color coat and even going over the area again it still wasn't quite right so your fog technique videos came in handy for a solution as I didn't want to paint it and I just wanted to thank you and your son for all your videos.
Morning N MC, you're welcome,
have a great day!

Hi again Kirk. I cannot find any fog coat products here in Spokane Wa. or anywhere in the Pacific Northwest areas unless I order it which would cost a bundle in shipping and since I only would need 1 – 25 lb bag to fog coat a 250 sq. ft area I thought I could maybe just make up a solution of white portland cement type 1 with hydrated lime type s with the oxide colors I have, to get the job done. My finish coat came out uneven in color and I want it to be more uniform. Could you please tell me the ratio of the cement to lime so I can make my own mix up? I am having a hard time with finding any information and just knew you would be the right person to ask. Thanks in advance.
HI N MC, what you can do is mix a bit of same color coat, water it down and use a few paint strainers to remove ALL the sand, and you're ready to fog coat, with the right color.
Best wishes,

Hi Kirk. I am winging it on this project so I have made a special non premixed color out of two oxide powder colors, so I will be mixing the Portland cement and lime with oxide colors. I did find out from a cement company lab guy today that the regular stucco mix is 21% white Portland cement and 5% lime so I just got the raw ingredients and will make up a large enough batch to spray the entire wall twice, just to be sure. It is the same color as the finish coat but it will be more uniform in color when I'm done hopefully. Thanks for your reply and help in this situation!
No worries N MC,

I have had 3 homes fog coated to different colors. It was fast and easy. There was no issues. whole house no scaffold joints. they needed color touch up in a few areas but look great after 6 years.
Morning Michael Chtistopherson, thanks for the input,
I have fog coated at least 30 homes but alway to pretty up the same color or to remove scaffold joints, there are some folks who do change the color with a fog coating, however not me, I tell folks if you want to change the color, we can pressure wash then apply by hand another top coat over the existing color finish this is permanent.
As is to remove scaffold joints or to pretty up a color you have to go over the area sometimes up to three times, this in my opinion is the max, any more fog coats will rub off as there in too much pigment saturated on the wall surface which becomes chalky, your hand can actually rub away the color, let alone the issues when it get rained on.
I have to guarantee my work for 10 years minimum and then another 10 morally.
This is my habit, to those folks who do change the color I wish them the best.

Love all of your videos as they are professionally done . Just completed a stucco job on my adobe studio here in Albuquerque (1500sq ft.) It turned out great, except the color coat which is two tone. Would you recommend a fog coat to remedy this? I dread having to trowel on a new stucco color coat. Again thanks for the great videos.
Evening Mate, fog coats take many years to learn the do's and don't's properly, if you have scaffold joints or say bleached colors due to wall absorptions you may be able to fog them out,
but a fog coat can't change a color, unfortunately, if there was a shortcut, I would know of it,
Cheers,

I forgot to tell my contractor to maximize the pigment load in my color coat. He just finished today and it is so pale the color doesn't really show. Should I pay to have him fog coat the same color with maximum tint? Or trowel another smooth coat of color? I'm using Portland cement stucco from Western Blended here in Arizona. Thank you for all your videos. I watched every single one before I hired my contractor.
Howdy Rene, if your going to change a color it's beat to apply by hand not a fog coat.
A good idea is to take out at least a week or two to see if perhaps the color applied is not so bad after all,
Best wishes with your project,

I’d like to paint my house. It’s an old stucco house and the patches are being covered as well as the cracks. What type of spray paint would you recommend if fog is not a good idea?
Greetings Martine, there are too many quality paint companies to list, however, I'm partial to Stucco-flex's Renew, type in the product name and read it benefits as well as warranty.
Cheers,
Sound Plastering tips from your favorite stucco geeks
Kirk is correct, fog coat is really to even color out on cementitious stucco finish. Sand finish is generally straight strength, skip trowel is 1- 1/4 strength, dash finish is double. It is always a good idea to have color packs to tune the color. It is an art to do it right. I worked my way through college fog coating in the 1970's.
Greetings Mr. Fowler, nice to get a comment from you. Any folks reading this, Mark Fowler is an editorial director for the magazine walls& ceilings and has written too many articles to list here.
Mark is currently the executive director of the Stucco Manufacturers Association and can be reached at mark@markfowler.org
Mark has unlimited knowledge in all aspects of plastering and stucco applications, little wonder he heads major magazine for major professional contractors.
Take care, my friend.
Sound Plastering tips from your favorite stucco geeks
Kirk, I need your help. I have a house and no fog coat around here. Can I use a fine sand acrylic finish and spray it? I know the color will not match because the color will be even but that's my only option.
Good Evening Jose, if it were me, I'd call a plastering yard such as westside building materials or any other plastering yard, bring in a sample and have them order the proper color you will need. It may take a week or possibly two. However, this is the appropriate way, besides you can't spay any type of sand no matter how fine as one tiny grain will cog the tip and shoot the color as a jet stream this not only wastes your time but ruins your day as well.
It's a beautiful acquired habit to practice patients than to be impatient and frustrated, this suggestion goes with most thing in life.
Best wishes,
Sharing stucco secrets and or common sense plastering tips
Awesome work and videos. I live in Phoenix AZ and would like to apply Allegro Cement Coating to my stucco. None of the painters I have talked to seem to want to take on the project. Can you recommend someone like yourself in Arizona?
Will a fog coat that is applied to even out noticeable marks left at scaffold line on a smooth stucco finish also ruin the beautiful concrete variation that occurrs in white smooth stucco (Santa barbara finish)? ie does the fog coat make it look more "Painted"? Or will it retain that subtle variation throughout of a smooth stucco finish? Thanks!
TRUTH SPOKEN HERE. a plasterer who actually knows fog coat does not last longer than paint. Fog coat in large areas can actually do damage on stucco creating chalk and make it hard for the paint to stick later on.
Hi Kirk I saw a beautiful house in southern california after it was stuccoed and I said I want my house like that. I found out that after they applied the brown coat and the finish coat that they will be fog coating my house to get the same look at the property I saw. Are you saying people dont fog coat any more?
Kirk is it okay to fog coat after brown coat and finish coat has been applied. I sent you a previous email different question but simuilar.
@kirk We just had our house stuccoed for the first time like a lace finish then color stuccoed (beige brown color) was applied My question is why are some of the walls look lighter than other parts almost like patches around the house . The guy who did the work said it needs to dry it’s been a week and I still see patches in color . Guy says it needs to be fogged now . Why do you think fogging is necessary? Thank you
I like what you say…. apartment associations want to fog coat instead of paint……. Go for it. the look on your face says it all…… sales gimmick
