Browse Forums Flooring & Floor Covering 1 Mar 23, 2009 8:02 am Hi All, I want to install Blackbutt timber flooring to my house which is currently under construction. I would like to know what is the best option.
I prefer solid timber flooring on a plywood or similar substraite. Some options i have considered. A. 19mm Plywood underlay throughout the house, then lay 19mm solid flooring on top in the areas where we are not have carpet etc. B. 19mm Yellow tounge throughout the house, then lay 19mm solit flooring on top in the areas where we are not haveing carpet or tiles etc. C. 12mm PLywood only in areas where we are not haveing carpet. Then 19mm solid flooring on top. D. 12MM Plywood only in areas where we are not having carpet. Then 12/14 structial timber on top. Not overlay (which is generally shorter peieces) and designed to be direct stuck to slab. I have been finding that 19mm yellow tounge is cheaper than plywood these days. Is it ok to fix yellow tougne to concreate then timberflooring to yellow tounge??? Comments greatly appreciated. Re: Option for Installing Timber Flooring 2 new House u/c 2Mar 23, 2009 8:20 am I am also interested to know the pros and cons for each one! Borg, from what I know, you must have at least 15mm ply for 19mm timber. An installer I spoke to, he advice thicker ply (>15mm) the better, provided the finishing floor height is not an issue.

The jury in the flooring industry is still out regarding the direct stick method of installation. Yellow tongue is not used over concrete. You can get very cheap DD ply imported from South America which is a lot cheaper than the structual Aussie made stuff. Its fine for laying under a floor. Re: Timber Flooring Option 2 new House under contruction 4Mar 23, 2009 7:30 pm Hey guys thanks. Yeah i dont really want to go down the path or 12mm plywood. I much prefer at least 15mm. What is a fair price to pay for 15mm plywood from south america? Do you guys know why yellow tounge is not used as a substriate. My thinking is that since 15mm is most comman that yellowtounge would not be strong enough but if your prepared to use 19mm then it should be fine. I am correct?? or is there another reason that i am not aware off. Re: Timber Flooring Option 2 new House under contruction 5Mar 24, 2009 8:22 am More than a few times, when I asked for prices for plywood, they asked me whether I wanted the good one or the cheap one from china. The good one are around $15/sqm. All of them don't even recommend the cheap one.

You will have a lip/small step? Ben LEADING THE WAY IN BUILDING AND CONSTRUCTION BUILDERSEDGE PTY LTD Re: Timber Flooring Option 2 new House under contruction 8Apr 14, 2009 5:15 pm A lot of builders bevel some offcuts of flooring so there is no 'step', just a slight slope into a carpeted bedroom. You can also throw some ply down under the carpet if you had the money. It would give the floor a better feel and insulating properties. Re: Timber Flooring Option 2 new House under contruction 9Apr 14, 2009 5:31 pm borg D. 12MM Plywood only in areas where we are not having carpet. Then 12/14 structial timber on top. Not overlay (which is generally shorter peieces) and designed to be direct stuck to slab. Borg, You mentioned something interesting here. You talk of 12 mm overlay timber and structural timber. I take it that strucutral timber comes in longer lengths (and probably costs more). The main 12 mm timber on the market appears to be Boral's Slimwood. And yes, I've noticed that they talk about random length, which worries me sinse I'm sure "random" means more short lengths and less long lengths. Can you tell me more about the 12/14 mm strucutral timber? I was originally going with Boral's Silkwood engineeried flooring, but have decided to change to a 12 mm solid timber flooring due to all the bad experiences here on the forum with scratching. Mine will be on 12 mm (or thinner) plywood. Cheers, Casa P.S. I would have voted for option D, but it's academic now. The reason is that it's easier to match to the heights of other flooring and there doesn't appear to be any downside.

The funny thing is that I forgot I even wrote that lol. Perhaps in my research i must of came across structial 12mm flooring, or maybe i was making an assumption that it existed. Regarding boral I have found the boral tend to be more expensive even in the raw material. However i cant see why you cant get 12mm. How about finding someone that can will down the 19mm to 12mm. I am hoping to get blackbutt standard grade (19mm) for 49-55 per square meter. I will let you know how I go. . Re: Timber Flooring Option 2 new House under contruction 11Apr 14, 2009 8:49 pm The structual part of the flooring you thinking of is probably the ply itself, most of which is graded F11. Casa, all timber flooring is sold in 'random' lengths - 19mm ranges from 0.9m to 6.0m and 12mm is generally 0.6m to 2.4m 12mm solid flooring must be secret-nailed and glued from memory ( I'm reasonably sure its not suitable for glue-only) It will need to go over 12mm ply, there is a short secret-nail (28mm) manufactured specifically for this application. Re: Timber Flooring Option 2 new House under contruction 12Mar 12, 2010 11:34 am Duke, I was wondering whether 12mm ply is fine for 14mm timber?

Can you help out with any info (installation method, price, where did you buy from etc.)?? Aaaaand, can you show us any pics at all ?? My signature is distracting people from my wise posts ... Re: Timber Flooring Option 2 new House under contruction 16May 07, 2010 10:34 am Hi Lex, i have to dig some up. I have been living on it for around 6months. Although house is not finished. I will update photos as soon as i get around to it. In my case i did the following 17/18mm plywood with 22 quick drive nails plastic sheeting for moisture barrier. 19mm Structural Blackkbutt flooring. Standards grade. Finished in two pack high gloss. The boards where secret nailed and glued using sausage in V shape to allow glue to dry properly. I wouldn't have done it any other way. Gloss floors are very easy to clean. However I wouldn't have gloss floors if i have select grade timber, as defects may stick out more. Although personally I would never want a select grade floor the more veins the better. But not too many knots. Re: Timber Flooring Option 2 new House under contruction 17May 07, 2010 11:00 am Thanks, borg. What city/state are you in? Or, can you tell me where did you buy the timber from and any indication of the price range? Trying to figure if buying direct from a big timber yard is better, or to leave it all up to the installer to supply ... actually, either way (and especially with blackbutt) I can never be sure what exact species they deliver. I mean, some blackbutt species are better than others. So, you only had the slab installation, no upper floor? Did you ask them to use that V shape (no idea what that is ), or would they have used it regardless? When you say 17/18mm, what do you mean? Didn't know that there is a ply thickness in between 19mm and 15mm My signature is distracting people from my wise posts ... Re: Timber Flooring Option 2 new House under contruction 18May 07, 2010 11:09 am Sorry lex, i missed many of your q's the first time. City = Melbourne V Shape is the way the glue is applied, its so air can dry it out properly, solid glue can have trouble drying otherwise it would dry in the tin but it doesnt so it must be true somewhat. I red it on some standard somewhere. The other option is trowed glue from tins. I installed the floor my self with some great help from my dad. hmm timber is like buying fruit and veg if you look hard enough you may find some real good tasting stuff where you didnt pay all that much, and no two batches are the same even if you buy from the same shop. All i can say is that the installers arent going to waste time looking around for something on special or better quality. they dont care. I shopped around and i think i paid around the $50 mark. I found a supplier that doesn't specialized in timber so had a bit of stock just sitting in warehouse. It ended up being there for a year. Was nice and dry and good to work with. Compared to some of the boral stuff I seen that felt lights and still a bit green and fresh. I am pretty sure that timbers are one of those things that fluctuate in price. So look around and yow might find a great deal. regarding authenticity get yourself familiar with the product and the viens and color. Once you will with it you will know what i am talking about. But you need to know before to make sure you dont get taken for a ride. Although i think with black-butt you will be right, there is plenty of it around. Timber installed was only onto slab. (single story house) plywood was 18mm but did vary by +- 1 mm. Re: Timber Flooring Option 2 new House under contruction 19May 07, 2010 11:18 am Thanks, borg Wow, how lucky was to find a seasoned timber !!! Yep, seems like they deliver stuff that has literally just been cut in the mill and then you're stuck with gaps after a season or two ... which is very confusing - where is that kiln-dried step in the overall process?! Do they dry the whole stumps before they cut them into boards?? Or, maybe raw timber is never dried?? My signature is distracting people from my wise posts ... Newbie question for flooring options.
