Question

HELP!! I cannot find any information on whitewashing on the web. I have an unfinished chair that I want to do, but there are no directions as to what type of paint to use and what the actual technique is. I noticed one user questioned the technique; is that all it is, take latex paint, add water and apply with a rag?

That is one way of doing it, I personally like to an oil based paint thinned down quite a bit, I found that the latex paints thinned with water will raise the grain of the wood and if that is the effect you want that is fine. I use a white oil based paint thinned almost in half with paint thinner (depending on the consistancy of the paint), I brush it on barely touching the brush to the whitewash, tapping on the side of can and apply to the wood, spreading it out evenly and watching for runs, it leaves slight brush marks at first but by the time it soaks into the wood and dries they disappear, it is probably easier for you to use a rag, it take a lot of practice to perfect the brush, be sure to get every little creavis, crook and cranny because any missed spots will show up good when you clear coat it. Don't sand yet, apply a sanding sealer, allow to dry, sand with 220 grit, remove dust and 2 coats of clear.

Another method is to seal it first, sand it, apply whitewash and wipe off(leaving it in the grain) and two coats of clear, this gives a different effect totally, it look dusty to me, like it needs to be wiped down, but some people want that. The first method actually soaks into the wood and changes the pigment of the wood.

az30,
I have never stained or whitewashed brick, although it may be something to experiment with (If one could find and old brick wall to do so) You may contact your local brick sales company and see if they have any idea's or contact the people here, they may be able to comment on the subject: http://www.4greatconcrete.com/default.htm they are concrete staining specialists.

Sorry I couldn't help more.

az30, Here is a post I saved from a while back from 2000. I will not edit his work so some will not apply. You may want to run a search in the DIY archive with the key word brick. This should turn up many threads.....Mike

While reading were you able to see a picture of the result? Today "whitewashing" is becoming a generic term. Many ways of whitewashing exist.
The three most common ways are traditional whitewash, thinned paint or stain, and masonry stain.
Traditional whitewash is a lime and water mixture. It may contain other ingredient to improve weathering but it always wears away and it leaves white stains behind. Non lime based formulas exist also. It's a simple task to make whitewash, however, it's sold under the name "Kaolin". Lime whitewash is unmistakable in appearance. It is dull and chalky. It can be colored with dry earth cement colors or the newer liquefied pigments.
Both oil and latex masonry paints have been used to mime whitewash. The mixture is an inexact science. Simply add the proper thinner for the desired consistency (very thin). Another paint, Portland Cement paint, a distant cousin of whitewash may be used also.
Whun using latex paint fur whitewash select the cheapest one coat masonry paint you can find, cousin, cuz high grade paint will peer more like paint thun whitewash. Utherwiz select a self chalking masonry paint. Either way will more closely approximate the whitewashed look. Without local information to the contrary avoid oil and alkyd based paint. If either is selected use more thinner (painters naphtha) than paint. Portland Cement paint when mixed to the consistency of thin syrup would perform well. The appearance with paints will vary considerably.
Pigmented masonry stain & water repellant is made changing the color but it may not provide the whitewashed look you're after. If you cannot find white, ask a sales clerk if one of the clear masonry repellents can be tinted.
It might interest you that for the most part whitewashing brickwork is a final act. It will require continued maintenance and there are no easy or cheap undo buttons. The type of brick, porousness, and wether is has been dyed or not, can limit choices of successful whitewash methods. For example, some brick are dyed with stain. And, red stain plus white stain equals pink, not white. Hard fired brick can be painted but whitewash and masonry stain do not adhere well.
Test the selected concoction in an inconspicuous area first. All of them may be applied quickly with a garden or deck sprayer.
