Hello there,
I am from Cyprus, a relativly hot country and i have the same problem with the joints of mgo boardsWhere are u from?)! Whatever method i use, i have cacks.The paradox of the situation is that, I dont get cracks evrywhere.....same materials under the same conditions with the same joining technic, either crack or not!I cannot explain it.The only thing tha i can gueess is that the mgo boards i have are not exactly the same with the same characteristics even though i bought them together from the same supplier.Are there different kind of mgo boards with diferent charasteristics?

What product did you us as joint filler and what tape did you use? These can make a real difference and did you apply thin coats or just plaster it on in 1/4" layers?

My question was asked as some taping compounds have adhesives in them and others do not, expense is not an indicator of this! As well fibre mesh tapes some are self bonding and others are not, I myself do not use mesh type tapes only paper set in a proper jointing compound not a topping compound.
If compounds are built up to much the top drys quicker than the lower and will crack as the lower need to expel the liquid, thin coats are the preferred method rather than slapping it on trying to hurry the job especially in hotter climates.

China has developed a reputation for manufacturing substandard products of all kinds.Their lack of environmental responsibility and cheap wages have caused legitimate companies all over the planet to close down.If you support Chinese products,in my opinion you deserve any problems that come with.

Actually there are different classes of mgo board in China. If you buy the cheap board, then definitely there will be a problem.

It's quite normal that buyers will send inquiry to lots of suppliers and selete the economic one to work with because they only consider price but not quality. Now the price of high class mgo board in China is about 50% higher than the cleaper one.

Anyway, mgo board is not that bad as your image. It depends on what kind of mgo board you use in your project.

Best Regards.

Christine,

You forgot to add that you are a MgO board manufacturer on this post. I'm sure it was just a minor oversight.

One issue with a Chinese products is regulations as to quality! In most cases there are none and as such it is always buyer be ware! They are starting to make gains in this regard but it will take years for it to make a real difference. I do hope they will do it quickly but I shall not hold my breath.

Hello Torben,

Yes, we are a manufacturer of mgo board in China, but this product is not all as bad as what you suffer now. There are still some good among them. Like human being, some is good and some is bad. It depends on which one you meet.

I agree, there are many classes of MGO board and the jury is still out to which
is the best board, manufacturer and supplier for a variety or reasons.

But , there are some very good products / boards that can be obtained and are
suitable for most types of end users applications and the quality and durabilty
has generally improved markedly over the last 3 years or so.

As the product is relatively new and the composition so different to what has been
so widely used in the past particular attention to the other matching compontants
needs to be given serious consideration to ensure all is compatable.
.
It is fair to say though that of the many , many manufacturers in China there are
only a few that can and are willing to adapt to the overseas stringent requirements.

In essence they dont have an understanding of the conditions that are applicable
outside their own country and perhaps dont really care.

Price is and will always be an issue when purchases are being considered and just
because one is either the cheapest or alternatively the most expensive does not
guarantee a good product or in fact good supplier and good service.

The most lacking from China suppliers we have found is they are not willing to admit
a problem may or does exsist and remedy the loss and have no idea of the real costs
bourne by the buyer of unsuitable products.  
Again , maybe they just dont care once sold..

But , its still a product worth the time and effort to explore its advantages.

Its not all bad.
There are some very good manufacturers which have good products.

But ,its a major event to find them , and then get them to adhere to the standards.

The communication process and understanding of the properties of the product that
is a issue that needs time and effort.

For them,  its all about orders and not much else.

The Problem with china many times is that you don't know if you are really dealing with the manufacturer or a man in the middle.

Hence there are even programs that show how important customers going to china a fooled. The so called manufacturer rents an office has some people doing someting, some products where people are working on and you get the impression you are dealing with a legit company.

Check stuff on www.alibaba.com and you see manuy companies all offering the same products, but who is the manufacturer ?
The next problem is that sure there might be differenc ein quality but it's common that when you ask for a sample you get a good quality and you open the container and oeps different quality.
since you pay upfront, try to get your money back.
Than you can pay someone to inspect the good before they leave, and sure the seller might pay this person more. This means you have to go there yourself and check the container.

But sure there are some good companies that do make quality but the problem is that it's difficult to tell if you are really dealing with a good company or not. Unfortunatly the mentality of many chineese companies is only selling selling containers, tkae cash upfront and solving problems, mmm never heard of of they say we fix next time.

I've never imported from China but done lots of export to China. Everything we shipped was against a letter of credit (LC) that required the goods to be received in good condition before we would actually receive payment (break the LC). It surprises me this not being done when goods are going in the other direction. I would never expect a good outcome buying from China, money up front with no recourse.

Torben;

I don't think the receiving of the material is the issue, it is like the case of chinese drywall, it looks OK, but you don't know there is a problem with the material until several months after it is installed .

Hi everyone, if you want to know more of MGO board, you can go to wconline website to read the artical written by Mr. Robert Thomas, who is USA nationally recognized EIFS consultant. http://www.wconline.com/CDA/Archive/BNP_GUID_9-5-2006_A_10000000000000194720 , the biggest manufacturer and distrubiter is in USA for MGO board, till now before we can have chance to have better construction materials that MGO board is the best one.

MGO board has so many characters and advantage that other construction materisl that cannot exceed. if you buy the MGO board from USA local shops in good reputation not in cheap price and you get the right installation instruction from them then you will have no problem.

Is there a guide on the cost comparison? I am looking at PUR SIP panels, and I'm not finding a lot of PUR MgO options.
