The house is mostly done and now I need to paint it.
All interior and exterior walls are finished cement.
Do I need to 'seal' this before painting? What kind/brand of paint do others recommend?
We will probably do this work ourselves for the most part.
You should seal it but most contractors don't bother, buildings that I have seen sealed don't seem to last much longer paint wise that I have seen.
For the inside just use cheap exterior paint, for the outside a good Thai paint is TOA, obviously exterior as well.
ICI Weathershield is the best exterior paint, followed by Joton.
^You seen the prices they charge? Probably alright for you mansion owners, but most people just own normal houses :)
Beg to disagree there DD, there can be a huge difference if you do a good initial job.Quote:

Use a thin sealant that can penetrate the cement surface and get a "grip" inside the cement.
TOA makes one that looks like milk and which will give you a rubber surface.
Surely the others (Supershield, Jotun) has something similar.
Then, use one of the 10 year guaranteed paints.
It will get a very good grip on the rubber surface.
I've always thought the expensive paints are cheaper in the long run.Quote:

PS. My house is normal.
I'm sure my neighbours have spent more money on their painting than what I have done on mine.Quote:

My point exactly.
The est advice I can offer is make sure the surface has dried out thoroughly after construction.
If you are using darker tint base paints go for the very best quality - the coverage and continuity of colour will more than pay for its self ( better than having to do 3 coats with crap)
If you use the cheaper stuff and the wall is too pourous, undercoat / seal with 1 parts bondcrete to 4 water (if you can get bondcrete in Thailand??)
Signed, a victim of interior decorating :)
I know what this is called but goddamn my memory, sorry.Quote:

anyway i will do that and follow up with a good, but cheap, exterior paint. all over
the open house is may 25. there are maybe 1,000 people in the village and i am told to expect 100 of them at the open house. since i am footing the bill i'm not surprised...
i am thinking most of them will want to use the farang toilet since that is probably a new experience for them. good test for the septic/soak system
Did you paint yet?
Seal and then use an enamel paint so you can clean the walls. It costs more, but will prevent you from having to repaint dirty walls all of the time.
Oh, and watch the painters. They will try and dilute the paint to nothing with thinner. Have them apply 100% no matter how many times they tell you they know better than you. i caught my painters hiding in a room dumping the thinner in :(
That's a very good and valid point. You have to keep an eye on them. I've seen some painters around here doing just that!Quote:

As with all painting surface preparation is the key.
Also there are two ways to seal one is for moisture seepage and it requires a waterproofing agent to be applied. The other is to “seal” the concrete surface for painting. The second “sealing” can be achieved using regular paint thinned at 10% paint and 90% thinner.
The concrete “sucks-up” the thinner and sucks the pigment along with it onto the “pores” thus sealing the surface. The next coat is applied at 100% paint.
I was given this advice by the paint rep. many years ago when I did my garage floor. I never had a single problem, no flaking, etc. Of course I also cleaned and etched the surface as well.
Maybe the milky stuff mentioned does not require the surface to be cleaned and etched? I don’t know as I have never used it.
we have painted the interior. we did it ourselves with the help of a local. we took the advice previously offered of laying down a thin sealer coat followed by a thick finish coat. i say 'a' thick finish coat since it looked good enough to me not to do another. my only complaint is due to my own rush to finish. we slopped paint everywhere. now we need to clean it up. not, i think, an easy task.
the exterior will wait until we have cleaned up the interior and finished moving. the missus wanted, rightly i think, to paint the interior before we moved in furniture.
we appreciate your advice.
This is correct BUT it is very important to firstly wet down all cement structures (footings, columns, and walls) for at least 30 days in order for the cement to cure properly. Note the plastic wrap wrapped around columns to ensure moisture is retained (a half-measure at best by contractors who understand the process but are too in a hurry to do things right).Quote:

In any event once the 30-day wetting period ends, you correctly must <quote Wait 3-4 weeks for the cement to dry out completely.unquote> and then continue to do as lom advises....Cheers:)
We have just been recommended by a painter to use TOA 7-in-1 for our exterior walls (concrete). Does anyone here have any experience with this brand/type?
There are some minor areas with painted wood which will have to be done as well, will the same paint be suitable for this as well?
Supposedly ...??? Joton is the best quality paint you can buy in Thailand, I used it and been ok for 5 years now.
