    Repainting a Townhouse (pair of them)

    Getting ready to repaint wife's townhouse and the next door one we bought.

    ...first...
    Blackish Stain on Painted Concrete
    Like so many other concrete structures I see around Thailand it has a large number of sizable blackish spots that I assume are associated with the very damp environment at times, and particularly when the concrete was new. In the states I've seen this in damp areas, and its recommended to use a product called Kilz prior to repainting.

    What is the best treatment (and product) to use here in Thailand?

    We were in Global a few days ago and the fellows recommended TOA 113 MicroKill. Is this a good one?

    I washed and mechanically scrubed the front porch & upper floor balcony areas, but those lofty areas on the side are too high for me to reach. I'm assuming these need to be prepped first by a good scrubing/washing,...then a complete drying,...then the Microkill,...then the paint (not new construction)

    A lot of Thais who own townhouses never repaint them. You would think paint costs thousands of baht whereas it is the cheapest outlay you can make to make the place look nearly new and a lot more presentable.

    In the past, I have used a mixture of ordinary bleach and water to scrub down outside walls here prior to painting with exterior emulsion.

    Whatever you use, this country is so dusty and polluted that after about 3 years a newly painted place can begin to look scruffy again so I keep some of the original paint handy and skim over the areas that start to get dirty, that way I can keep ahead of the thing and the original clean look lasts longer.

    I was painting my outside wall a couple of years ago, it's a big wall around more than one rai of land, anyway this old thai guy used to walk by and stand there watching me everyday then at the end of the week he said hey you how many tine of paint did you buy.....?

    I said 12, with that he goes away and the next thing I see him painting his wall.

    After a week he comes back and said to me hey I have 6 tins of paint left.

    I said so have I

    I thought it was just the general nature of painted concrete or block, combined with the very moist prolonged wet season.

    I had a house in Florida at one time that was basically cinder block exterior for a large part. It calked up somewhat similar to the surface I was cleaning off the other day. I had to get all of that powery dust-like surface clean before putting on a good quality exterior paint,...and that would hold up for a good ten years. It just appears as though there is more of a 'blackening' tendency here to the concrete surfaces.

    Get a good quality paint, otherwise you will just be wasting your time

    TOA do good exterior paint, Supershield exterior

    depending on the design of your walls etc, you may get areas that get black due to water runoff and subsequent dirt left there. These can be easily cleaned now and then with water and soft brush, maybe with something like Sugar Soap as well

    the paint stays good though
    I have reported your post

    The shop house next to us decided to paint their inside and outside and got a professional to do the job. At day 4 the Professional walks over to us and asks to paint our outside. I was currently painting the security doors due to the 2 meters of flood water.

    He showed us the paint brochures of the excellent TOA exterior paint that would last us for 20 years. We agreed he could paint the outside for 1000b if he went and bought the paint at the local TOA shop. All was agreed. The premium exterior paint, color, the area to be painted, the required priming of the surface before painting ... what could go wrong.

    Well, preparing the surface was basically running a puddy knife over any flaking paint. He would not paint near any electrical wires. Tiles now have a nice blue artistic flecking from all the paint spatters. Cut work on railings look like a 10 year old was learning to paint within the lines. All this is acceptable. What I really found hard to accept was the turd went and bought INTERIOR paint. I noticed this when he came to get paid. For 20 minutes I tried to explain to him .... wrong paint .... no good. Not what we agreed to!!! But as he pointed out ... The TOA interior is great paint and cheaper than the exterior and he is a professional so he knows ... not a problem.

    What a Toad! So I am expecting it to look great until the sun and rain decides to have fun with me. Hard to believe, welcome to Thailand!

    I think I have found an honest contractor,...but just to be sure it sounds like I need to go buy the paint myself...then insure its not thinned down to much.

    I'd paint the thing myself, but its too far off the ground...particularly for my age

    Always buy the paint yourself and only pay the contractor for his labour.
    That way you get the product that you want, he won't water it down, and he also won't mark up the price of it.

    Yes he will, most paints in Thailand are thinned down, regardless of whether they are water based or oil based. It even says on the instructions on the can of paint how much to thin it down by.

    Well he'll more likely water it down to specification, rather than water it down too much just to make it spread further and to save himself a few baht.

    Well if I had your avatar doing the painting above me I might try to reach those higher spots.

    Yes I took note that I should buy the paint myself, and look over the painter shoulder to see his mixing ratios. I personally feel that once there is a good binder coat on that concrete or block, then it should be completed with as thick of a paint that will still spread easily.

    I was really looking for all the advice I could get on the proper treatment of those dark bloches one sees on all this rain drenched cement.
