Browse Forums Landscape & Garden Design 1 Jun 08, 2011 3:45 pm Ive spent hours trying to find information on the net and throughout this forum in regards to detailed information regarding the constructions of a blue board wall. I cant find any construction info on the James Hardie website, nor any others. Can someone please direct me to, or advise of methods required. I was looking at using 90x90 timber posts with 90x35 stud infill but a chippy friend said to use steel posts with 90x45 timber infill as this will reduce movement and cracking? He has also suggest spacings of 600mm for posts and to use treated pine? Is this all correct? I think that covers the main basics, but my main concern is how to avoid cracking at joints. Is there any special techniques or materials I require in order to have these joints properly sealed? Any advice would be greatly appreciated. (apologies if there is info on this site and i missed it!) Re: Blue Board Construction 2Jun 08, 2011 3:57 pm I can't offer any help but would like the answers you seek also. I too have scoured the net for info on blue board as feature walls and turned up not much. Everything I know comes from snooping around display homes. I'm just concerned that a DIY job by me will look DIY. Especially with the joins a they are my main oncern also. NO EXPECTATIONS, NO DISAPPOINTMENTS!

Re: Blue Board Construction 5Jun 08, 2011 7:21 pm Try searching "blueboard render finish" and you will get a few hits. The big problem seems to be getting a good finish on the acrylic joint sealer. Most also suggest using a base coat of the same acrylic so the render or render substitute drys with no variationin colour Building an Eden Brae Saville 27 http://karry327.blogspot.com/ Building thread https://forum.homeone.com.au/viewtopic.php?f=31&t=44247 Re: Blue Board Construction 6Jun 08, 2011 8:03 pm We have one - it's on a timber frame, and has a rendered finish. There are photos on various threads here... I'll try to find the one with the "during construction" photos.

Steel is not necessarily important to prevent cracking timber can be used. treated pine is better especially if it is touching the ground. I do like the idea of steel posts on the ends though. Cracking is only likely to occur at joins. So to prevent cracking I used exy and hammered it flat and nailed it over the joins and rendered over it. Also minimize the number and locations of joins. You also need to make sure you are using blue board render. It is actually a bit hard to get and not everyone stocks it. It is more flexible then normal render and three times the price. Re: Blue Board Construction 9Jun 09, 2011 9:59 am ok thanks for the info. to reduce the number of joints would it be reasonable to install the blue board horizontally then? it would be much more efficient this way for me. and just another quick query - how thick would the blue board be + render + paint? about 20/25mm? (7.5mm for blue board + approx 15 for blue board render?) cheers Re: Blue Board Construction 10Jun 09, 2011 12:42 pm Best method would be to use sheet widths, 900mm 1200mm. Then have a protruding column or offset then set back sheet width again, will also add to the interest of wall, something like this -----II-----II---- Landscape Design & Construction http://cherub.squarespace.com/ Re: Blue Board Construction 11Jun 09, 2011 12:43 pm Best method would be to use sheet widths, 900mm 1200mm.

Is this all correct? just worked out my spacings and amount of posts - im looking at approx 32 posts! (that is with a length of approx 19m.). 600mm centres for posts seems overkill ! sheeesh! gonna cost a fortune!
