    Flat roof sealer-Where to get?

    Hello,
    I am looking for elast-o-meric sealer. Like in the states for flat roofs, specifcally for concrete flat roofs.

    Have no idea about the sealer you asked about, but do you really want that flat roof here in Thailand? Even if you have a flat roof now (for some reason) a slight slope would surely work better. But I ain't an expert. They will not doubt post an answer later! Listen to them and not me...

    I would be interested in hearing more about flat roofs. I would like to have a roof patio. Part under roof and part open for plants, garden, etc.

    I know someone who has a flat roof and the concrete just heats up to a silly temp and makes the house uncomfortably hot.
    A roof patio would cure this if it puts the surface in the shade.

    Tile it with nice ceramic tiles, I have never seen a concrete flat roof in Thailand, they all sag in the middle and that is where the water stands and slowly seeps into the concrete and slowly destroys your rebar and slowly then seeps into your building, yep go with tiles, floor tiles that is.

    DD Thanks for the information. I like the idea of floor tiles anyway since I want a decent patio under cover on top of my house.

    Do you think with the tiles plus a slight pitch/slope as in regular on ground patio's would do the trick to keep the roof dry?

    I would like a swiming pool there too, if I could aford it, but, I can't so back to dreaming.

    Yes, it will. I've just had the same done to my house. I'll post some pictures in a week or two.

    When I was in the Philippines a friend of mine was building a monster of a house, but a good looking monster. Large enough for the extended family. My friends sister had married a rich man from Japan. He was incharge of the building of the house. It was almost finished when I was last there two years ago.

    The house was approximately 40 feet X 70 plus feet overall. First leval had 12 foot ceilings except in living room which was open to the second floor ceiling. First level was, going from front of house to rear, living room, dinning room, kitchen followed to the rear by maids quarters, lst floor bathroom, laundry room,etc. A nice staircase wound it's way to the second floor from the living room.

    The second floor had one hallway that ran down the center, from the balconey over the living room directly to the rear of the house and fire escape. On each side of the hall way was bedrooms. Three on each side so on the second floor there was a total of six bedrooms, each with a private western style bath.

    The third level is what impressed me. Going up standard cement steps to the third level you entered one very large room, almost like a fancy warehouse. Completely open at the rear of the house. At the front of the house on the third level was two guest bedrooms each with a private bath. Then you got to the stairs and going back almost 2/3rds of the house it was just one big open room with electric lights, overhead fans, but no windows. The two front bedrooms had windows, but that was the only windows on the 3rd level. There was no rear wall to the house on the 3rd floor.

    From the front of the house to approximately 2/3rds of house there was side walls as in a regular house but no windows. For the final 1/3 of the 3rd floor the sides and end was enclosed with a short wall of about 4 feet. The roof extended the full length of the house.

    Here is where I fell in love with a roof top patio under cover. Completely private, discounting of course that this was an extended family house. Nice breeze, view, and very comfortable. Pool table, ping-pong table, darts, bar all in the open area with walls. TV, Music, etc, the works. About 3 or 4 nice outdoor patio type tables and chairs.

    What a place to entertain friends or simply relax. I have no idea what it cost.

    Don't forget to put guttering around the edge of the flat roof. Mine used to be like a water-fall at the back - right over the back door - until I had a gutter and drain-pipe put in.

    I would assume my builder would do that as a matter of course, but you never know with these Thai wannabes.

    The differences between the houses around where I am now is quite amazing. They are all a similar design, if not identical, but some have gutters and drain pipes, most don't, some have mozzy screens, some don't, some have metal security grills, most don't, some have spikes on top of the walls, most don't...

    I think the difference is that some houses have been bought and the new owners have had the extra stuff added, and the other houses are rented.

    OK - this is not quite finished, but it shows what I've had done.

    Looks good. What is on the other side of the wall on the right? Where's the chickens? Only way to complete a grill is to get a chicken turning

    The other side of the wall is next door. They're Thai, so you'll never see them on the roof. The end where the BBQ is, is the narrow end. The other end looked like this before the tiles went down.

    It is a drain hole, and it was put there by a Thai.

    Are you sure it's not an overflow pipe, for a very shallow swimming pool?

    Are you going to cover over the top/roof over or provide some sort of shade cover?

    When we bought the house, we had an addition built at the back so we d have a bigger washroom, about 8x11 feet. The roof for that extension is flat but tilted so that the water runs to one corner drain that connects to underground drains that run around the house. I did use a clear sealer (made by Jotun) but the UV rays have burned it and it's now flaking off after 2 years. The concrete has also cracked in places but there are no major leaks inside except for a drip on the counter corner where small ants seem to have dug a way out and over the door frame when there is a heavy rain. There was also a piece of styrofoam that found it's way up there and was partly blocking the drain like on the picture above.

    I get my paint and sealers for free so this time around, I got 2 different sealers, one clear, and a self-leveling rubbery plastic sealer to apply over it (Jotun again). This second one is flexible once dried and apparently will not crack.

    If that fails in a few years I will definitely go for the ceramic tile option.


    About the ant problem, I have removed cabinets from the walls in the washroom and emptied whole cans of bug spray into the holes I had drilled, haven't seen an ant since.

    Yes. I will eventually build a gazebo type thing with plants growing up and over it. I'll post piccies when I get round to doing it.

    The balcony is over the kitchen and bathroom of my wifes family market which is made of concrete . It looks as if they where placed in sections like a tongue and grove application and probably the seal between the seems have worn, allowing water to seep into the living space. I need advice on what material is availible ie., at "Home Pro" in the states we have somthing calling snow white which can be purchased in "Home Depot" which when cures is like a rubber membrane and seals very well.

    my house on koh phan ngan has a flat roof, seemed a good way to increase deck space and maximise view.

    note that the rusty steel was a prototye, we will not be using cattleguards, but tensioned stainless instead.
