Surface Bonding Cement

Postby Rimtalay » Sun Apr 05, 2015 9:23 am

Hi, have any builders on coolthaihouse.com used Surface Bonding Cement previously? I've made a few enquiries at different building supply companies in Thailand but unfortunately I've come up zero so far.
Surface Bonding Cement is used in many countries especially the USA, here is a list of just a few of the products available overseas

The Surface Bonding Cement uses fibreglass strands in it, this makes it extremely strong and resistant to cracking.
Thanks

Hi CTH builders, I was hoping that someone here may have been able to help me with my surface bonding cement enquiry, although I thought it might be a tough ask.
I've taken a look at lots of building threads here on CTH and I'm surprised that nobody seems to have tried using the surface bonding cement system, even just for rendering instead of doing it the Thai rendering way.
Then again if you are using Thai builders you're about 50 years behind the times.
The surface bonding system gives a far better result as it uses the AR fibreglass stands in the mortar plus addition of Calcium Chloride and Calcium Stearate in the mix, gives a waterproof, strong and crack resistant finish plus it only needs to be 1/8" thick rather that Thai type mortar which is weak and crack prone and usually up to an 1" or so thick.
In Australia and USA AR chopped stand fibreglass has been used for a long time combined with cement, I first used it in a commercial factory build some 20 years ago.
A paper was written "Strengthening Paster Wall Systems" some 25 years ago
http://www.awci.org/cd/pdfs/9010_c.pdf
Research was done into this method by the USDA in 1967 "Construction with Surface Bonding"
http://naldc.nal.usda.gov/download/CAT87210094/PDF
As you will note in the above document published by the USDA in 1974 , it gives the formula for making the Surface Bonding material, so I guess that since it isn't available in Thailand I'll have to batch up the cement myself.

AS you've looked at a lot of the building threads you will have noticed that many people here are using Superblock (AAC blocks). You'll also have noticed that AAC blocks require a special render.
I believe surface bonding cement requires pre mixing in exact quantities (in bags) and that it contains material that can and will cause lung damage if the required safety masks are not worn. Try telling that to the Thais who either don't want to wear face masks or have no inclination to do so because of the heat.
As well it has no resistance to heat and is the same as building out of concrete blocks, which is not exactly good practice in this climate, especially as AAC blocks are available at the same price.
Not only that you have to lay all your blocks on the stuff, which means added expence when laying your first bed of bricks and subsequent rows.
I read the PDFs' and can find absolutely nothing that would convince me to spend hours and hours of supervision (with the Thais) just to use a commercial product that is not suitable in this climate.
To achieve the same bonding effect, with the flexibility, all you need to do is use a Lanko product when mixing your render material.
If you are pouring a slab on top of prestressed concrete planks the same would apply in using the Lanko product, which is both a bonding agent and also far easier to use, as well as far cheaper in the long run.
If you gave a Thai the option of building with light AAC blocks or heavy concrete blocks I know which one he'd choose. Its taken a long time to educate Thai builders and their employees about the benefits of using AAC Blocks, are you suggesting we send them back a further 25 years by bringing back concrete blocks and keep our houses at a constant 100 degrees?
So far (in the PDFs) I've seen nothing that would induce me to even consider that option, especially regarding costs.
Are you sure the above posts were not for commercial purposes?

Maybe a different mindset would serve you better in getting responses from the many on CTH who have 'served their apprenticeship' ..... in adapting their wants when building within the constraints of the Thai "this is the way we do it" system. Works for many of them ... if you want something different then you have to tread the path that others who want to 'move things along' have trod.
