Q: I wish I could build my own Adobe home. Unfortunately I am just renovating so that I can have the look of Mexican design. Specifically I am looking for information on how to make stucco walls, color washes, and beehive fireplaces. Can you tell me where to go for instructions on how to make my current brick fireplace look like a beehive fireplace? I am wondering if I can simply put something over it to make it look like a beehive fireplace - should I use some mesh and then a stucco mixture. And what typically goes in the mixture. A: I hate to be so smug, but we have dedicated our lives to doing the real thing. Twenty-five years homebuilding and not a one framed. All adobe. The adobe look can apparently be achieved with chunks of foam board covered with various plasters. There are lots of plaster virtuosos in every state. Q: I was wondering if you could answer my question about a remodel of my brick f/p into and adobe style one. I do need to know if there are special materials on the market (CDN); does it need a 'frame' ie: wire to be fastened onto the existing brick or is there some kind of stucco/masonry, etc. materials that I could improvise with? I want to eliminate the sharp angles and replace/remodel them into a more rounded (pleasing) shape. A: Use expanded, galvanized metal lath to form the curved shaped. Standard gypsum based plasters will cover the lath and give the desired shape. As long as their are few air voids behind the lath, the fireplace facade will be very strong. Q: What can I add to my mud to give it that dark brown "wet look"? A: Several coats of boiled linseed oil. Apply it with brush, roller, or rag to an adobe surface once it has dried. Remove anything still on the surface after 20 minutes or it will turn gummy. We have used various oil based varnishes if the linseed does not impart enough dark brown color. Some folks even apply a layer of polyurethane or a clear varnish on top of it all. Every dirt works up differently so you get to experiment a bit to find out what works to get the result you want with yours. Q: I have a small mobile home. I want to do an adobe siding??? Can this be done and how would I go about it . I don't want to do bricks. I don't know if siding is the right word but I want it to look adobe. A: Paint it brown. Q: We just bought a home in Southern Utah. The upstairs rooms walls are adobe . We are trying to remodel and make this room suitable for our young children. It looks like someone has wallpapered at least 3 times. How can we finish these walls. The adobe is coming down, the wallpaper is cracking, and the plaster is falling.Is there a certain kind of paint to use, cement? What? We can't leave the walls bare. A: Wow! Sounds like a real mess. If the plaster is coming off the walls, I think you will just have to remove it. Once removed, the wall can be plastered again with adobe plaster if that is what was used before or a gypsum based plaster such as Red Top which is mixed with three parts of sand or Structolite which is used right out of the bag with water. Anywhere the wall is in good enough condition to be mostly solid, you can paint over the wallpaper, mud plaster over it or Structolite over it. If you choose to paint and if there are ridges left by the wallpaper, you can smooth that up with a big wide sheetrockers taping knife and a bit of joint compound. If you are really, really lucky you might be able to make chunks of falling plaster stick in place with Gorilla glue which is a urethane based product that has proven to be pretty amazing. This is just a guess and you might be the first person to try it but you could get your name in Reader' Digest if it works. Q: I am in the process of purchasing an adobe brick home. The bricks in the home have been painted over, home was built in 1960, and may have several layers of paint. How do you remove paint from the bricks? Is the only manner to remove the paint, sandblasting? Will this process damage the bricks? The inside of the home has also been painted, however we will most likely sheetrock. Do you have any suggestions for ensuring this process is done appropriately in order to prevent mildew? A: I have never tried sandblasting on adobe. It might work but it might take a lot of the adobe with it. Never heard of anyone else doing it either. Might just have to find a strong scraping tool and tackle it by hand. Sheetrock? Why buy an adobe house in the first place? It totally ruins adobe walls' thermal characteristics to have an interior surface that is not in thermal contact with the adobe. With sheetrock there will be an airspace to accommodate the presumed furring. That airspace is also another opportunity for those little mildew critters to get a start in life. And that interior paint may act as a a vapor moisture barrier to keep the adobe wall from breathing. If you do use sheetrock, rough up the interior paint in as many places as you can to break the moisture barrier. Q: My husband and I are about to purchase an adobe home that was completed in about 1989. It seems both the interior and exterior walls were later painted with standard house paint. We very much would like to remove this, and revert to the original natural finish. Any clue how this can be done? A: Sometimes if you just dampen the wall the paint will fall off or can be easily scrapped off. I have a three head mister from a plant nursery that works nicely to apply moisture at a fine, controllable rate. Spray it until it begins to run then move on. Go back over the wall again and perhaps a third time. Then, good luck. It may be very easy or it may take a lot of work. We got fooled by wallpaper that was on an adobe wall once. We thought it would come off so easily. It took a lot of work. The wallpaper hangers past had penetrated well into the wall and the created a strong composite surface.

We are using structolite plaster on most of the interior walls but we have several that we want to leave exposed. What do you recommend for a finish on those that will keep them as natural looking as possible but keep them from "dusting"? How would you go about applying such a finish? A: Exposed adobes can be washed and smoothed a bit with a sheepskin, a towel, a rubber float from the plastering trades or even left as is for a crisper look. Actually the wall is usually fine with no finish and visitors just have to be reminded not to rub the walls. It they rubbed painted sheetrock walls over a year old, they get chalk on their hands. There is a clear finish that waterproofs the wall yet allows it to breath. It is OKON and comes in two formulations, W-1 and W-2. I can never remember which is which but don't need to. A competent paint company that carries it will have employees who can advise. (Home Depot and such outfits may not.) Q: My husband and I purchased an adobe block home that was built in 1978. The exterior walls have been painted off white which is in poor condition (i.e. peeling). Is it possible to restore adobe walls to their original appearance after they have been painted? Soft red brick peeks through some parts of the peeling paint. Any suggestions? A: Yes you can. However, if this is an exterior wall it may introduce new problems. Most of the acrylic finishes are close to zero permeability: they do now allow moisture in but they also do not allow moisture nor moisture vapor out of the wall. If there is any source of moisture into the wall it becomes trapped behind the acrylic. Then the acrylic and whatever it is adhered to falls off the wall in a chunk! The best treatments for plastered adobe walls is something that has some small amount of permeability. El Rey Stucco has a product called Adobe Sealer. It breathes and allow any moisture vapor to escape. I think Thompson's Water Seal also breathes. Don't take my word for it; make sure it mentions permeability or breathability on the can, sack or container. Q: I live in Yucca Valley California. My wife would like for me to transform our house here to a Santa Fe style Adobe home. I am in the building industry and could easily make this house look like an "adobe" home with conventional practices that are being used here to achieve that look. But I just can't bring my self to make a fake copy. Are there any sources that you could direct me to that would show how this could be achieved and if the soil here Adobe quality. I would like to leave most of the exterior walls of the core house and redo the exterior in adobe. The new portions of the house would be entirely out of adobe. Q: My mother-in-law owns a Chapman Taylor mud brick house. Her husband recently passed away, and was unable to pass on some of his local knowledge about the repairs he often made to the house. I was wondering if you would be able, to advise us on how to repair cracks on the inside of walls of such a house, as we are planning to tackle this job shortly. We wish to paint a room which has cracking and some fairly large holes (1-2 inches wide in places- but not very deep) in the plaster (PS - I'm unsure as to the nature of the existing plaster). Basically, all we wish to know is: 1) What material do we use to patch up the cracks and holes with (fine cement??) 2) What do we then seal and paint over with? Any other information would be very much appreciated. A: Cracks in adobe bricks and plaster can be filled with just dirt. Sometimes a wet washcloth swirled around on the surface will wet the adobe and move it in to fill cracks.If the plaster is gypsum, lime, or cement based then most spackling compounds will do just fine. It takes very little practice to learn how to feather the compound into the surrounding plaster to make it look like new. Most modern water-based latex or acrylic paints work just fine. Some brands will recommend a primer which they will name, some brands are self-priming. In short, its not any harder than repairing sheetrock walls. Q: We want to add on, so how should the appearance be with adding on to match what is existing; could we stucco the old and the new to give it an updated look? A: New stucco can usually be counted on to blend new with old and to fix old problems. Q: I built an adobe fireplace in a newly constructed room. Have one in existing house already. Existing adobe fireplace has a sealant on it and then painted. Like the looks of just the adobe on the new one. Can I just seal it and leave it natural looking? Asking question from two different perspectives: One durability and one current trends. A: You can seal it with OKON W-1 or W-2. I can never remember which one is best but it does not make a lot of difference. http://www.okoninc.com/ You can also just leave it alone. If your friends keep rubbing it, get new friends. Friends don't rub friends sheetrock walls, do they? Current trends, especially in Europe, South America, Asia and just about everywhere except USA is to leave it as natural as possible. Maybe just a simple mud plaster or mud wash or just rub the fireplace with a wet towel or sheepskin until the outline of the bricks just begins to fade. Also El Rey Stucco makes an adobe sealer. I don't see it on their website so maybe they dropped it from their product line. http://www.elrey.com/datasheets.php Crown Seal Stucco Protector might be worth looking at. I would call their technical people. You could also spray on linseed oil thinned 50/50 with mineral sprits or turpentine. It will bond the surface together. But be careful to not get it on too thick. A thin coat will still have some moisture vapor permeability (breathability) so that moisture that gets under the surface can move back A: Beeswax is the latest rage in Santa Fe. I understand that it is best done with nude, youthful bodies hurled at plastered surfaces. Santa Fe parties differently than the rest of the world and us outlanders consider it an affectation of the multimillion dollar casitas as each neighbor tries to one-up his neighbor in costly adornment. It is certainly not out of the vernacular tradition. It gives structolite or diamond plaster a lustrous sheen. I don't have any idea how it would work on adobes or earthen plaster. Q: I am building a passive solar home in southern Colorado. The home is stick and timber frame, but I am building an exposed adobe wall in the corner next to the wood stove to act as a heat sink. My old home in New Mexico had exposed adobe walls that were painted white. What type of paint should I use to prevent moisture build up in the wall? Do I need an OKON sealer on the wall before painting or will painting negate the breathing features of the sealer? A: Wall breathability is really not much of an issue for an interior wall. Most of the forces that drive moisture vapor through a wall depend on the temperature and moisture differences between the interior and the exterior. Okon is not moisture vapor impermeable so it works as a sealer. I don't think it is necessary and just cheap latex paint seems to work as well as anything on adobe walls. An oil based paint might be just a bit better since it takes longer to dry and penetrates a little further. Usually the oil is linseed which is what we use to toughen up floors. Really, just about everything works on adobe. Q: We live in San Rafael, Argentina. We have a small organic finca, approx 20 acres. We have an adobe building on site that needs repair. It has crakes in the walls and the outside of the building is starting to show weathering. We have an Argentine family, that helps us take care of the finca, living there. We wish to repair the home so that they can live more comfortable and safer. Can you help us?? Any information on repair or other web sites that will help us to repair the adobe structure will be greatly appreciated. A: There are all sorts of schemes to repair cracks in adobe walls up to and including injecting epoxy adhesives. The good news is that just plain mud can be pushed into the cracks and packed in with a stick or small flat board that fits the opening. We have a conference here in El Rito in May and one of the well known presenters, Marcial Blondet, from the Catholic Pontifical University of Peru in Lima will present a paper on just plain mud. There will be no Argentineans this year but there are some knowledgeable people at the University in Mendoza. I guess there are two universities but the one that is in the park with the lake and yacht club is the one. Once my memory straightens out, I will be more specific. As for the exterior, if it has no plaster or mud plaster it is easy to fix. Just pick up the dirt at the bottom of the wall and mix it with water in a wheelbarrow and trowel it back on the wall. It can even be done with bare hands but I prefer a trowel. A hawk and trowel in fact. A hawk is the wood or metal plate with a handle underneath to hold a bunch of plaster to load on the trowel. |
