Hardboard? Ceiling Replacement Cost Per Sqmetre?

[Thailand]

Termites have paid us another visit after 5 years, can't believe the speed at which they move!

Anyway, they have eaten a part of a ceiling but I want to replace the whole area about 25 sq metres. Just want to get a rule of thumb costing for when I get the estimates to make sure I'm in a fair price range.

Fortunately that was the only area that was affected,and yes we do spray. But now a new company!

I am assuming your ceiling is internal; in which case it wasnt a great idea to do it in hardboard, lovely food for the mites.

Hardboard generally very thin 3-6mm max, not good for ceilings, any slight dampness and it looks like a bumpy road.

Ceilings should be done in plasterboard and skim and the thickness depends on the spacing of your rafters or ceiling joist.

Plasterboard 9mm (2.44m2/sheet) approx 150bt

12mm sheet 170bt (12mm is best, stronger and for 600 joist centres, dont use 9mm)

25kg bag skim which will do say 10m2 approx 400bt

Allowing for waste,you need to be looking at around 12/13 sheet and say 3 bags skim. Roll of scrim tape and a box of bugle head screws.

labour will be free becasue you are doing it yourself of course! (otherwise allow for a 2 day job)

so that option will cost you say 3-3.5k without labour

You can of course line the ceiling with plywood, its stronger but still needs treating and after staining. Price for 7mm ply circa 300bt

And ply option around 4k/5k with stains and pest spray and no labour

hope that helps?

Can you add a little detail?

It may well be plasterboard,I have no idea. As for DIY. I have dumb hands and fingers and would probably cause more damage.

Thanks very much.

hahaa, well if its eaten away an area you should be able to see what the material is with your eyes and a screwdriver...

hint:dont stick the screwdriver in your eyes!

I had the termites eat my ceilings on my lower floor and i replaced the ceiling with a suspended ceiling with 60x60 tiles. This no lets me to life the tiles and spray around above the ceiling. the original ceiling was plaster board and they eat all the cardboard on each side of the plaster board. I replaced the ceiling myself and the cost for my lounge was about 2000. It's an easy job and have just done one for my neighbor with the same problem. I recommend the suspended ceiling as there is nothing for the termites to attack in the future.

Best of luck.

There are many cementboards that rot and termites proof use for ceiling: viva board, eterpan board, shera flexi board , there are more brand you can ask more information at the construction shop about cement fiber board.

Agree there are many solutions, but we dont know the OP exact situation here to make the best judgement. The cement boards are great, but not sure I would want them in my lounge. outside, carport,garage..yes for sure.

As also mentioned plasterboard is not immune, as it is made from paper and wood and gypsum, perhaps a foilbacked board in a roof ceiling is better...those termites wont like that silver foil on their fillings I am sure

Now you tell me!

Thanks for all the great info guys.

"Cement boards" in the past contained asbestos if that matters to you. Installed and painted, probably not much of a problem but the cutting however limited will leave some nasty dust and you can't contain it.

You said it, in the past, and thats the long past. The asbestos isnt around now in new building materials but still you are correct to highlight and even the cementitious products now are carcenogenic so mask and gloves always as a safety measure.

more likely to end up in hospital after falling off the ladder though

What confirmation do you have that asbestos is not used in the new building materials?

2004 data indicates that Thailand was the 4th largest user in the world, 90% going into building materials. Data for 2009 still shows Thailand ranked 5th importing over 120,000 tons.

An article dated May 2012 states:

"To a seasoned observer of the global asbestos scene it comes as no surprise that asbestos vested interests in Thailand are liars. The asbestos business worldwide is based on lies: lies told to governments, customers, workers and the public. But steps taken by the Thai lobbyists have put these individuals in a class of their own. Where other vested interests may have tried to spin the truth to their own advantage, these industry stakeholders engaged in out and out, bald-faced lies.

Further, a May 2012 Bangkok post article states:

Vithaya Kulsomboon, associate professor in the Department of Social Pharmacy, Chulalongkorn University's Faculty of Pharmaceutical Sciences, said only three manufacturers in Thailand _ the Siam Cement Group, Mahaphant and Bendix _ have stopped using asbestos in their products after the previous government declared it a class 4 hazardous material last year.

Dante: you are certainly more correct than I was!

I hadnt realised Thailand still manufactured with this product.

My rash statement was based on the UK and EU and USA where it has been banned from all manufacturing for a long time. I have read that infact 47 developed nations have banned it outright and although Thailand still buys it from the likes of Russia and China the 90% use in building materials is actaully only roof tiles and concrete sewer pipes. (the irony here is that it was originally introduced as a fire retardant....when did you last hear a fire engine here?)

The inherent danger is now not to the "building occupier" but to the general public during the process of demolition.

food for thought when you wander past a demolition site

You never mentioned where you are ?

Old board will have to be removed at a cost.

Higher floors extra

Did you want standard, green board for wet areas, or foil lined ? Basic is about 200 Bt a sq.m others slightly higher.

Insulated can be much higher but well worth it if your homeis hot.

Remember priming and painting too after

[cheeryble]

You better check the ceiling joists they can be replaced with pressed T-section if you wish them to be invulnerable in future....

For those that may be interested.

The whole job including removal / disposal of 25sqm of old ceiling, new plasterboard ceiling, replacement of coving and cosmetic finishing,labour, is around 5500฿ 2 days work.
