a recent oak herringbone i done. Whoever screeded the floor was a perfectionist... i was like a snooker table, i didnt need any levelling compound, just DPM (sika primer MB). I used bona S760 adhesive
Hi dsmart, welcome. Did your client request to have the herringbone installed as "elbow" pattern or is this the way you always install this pattern? Looks good though.
Hi... Thanks The client actually showed me a picture of what they wanted in a magazine. Although this is how I would generally lay single herringbone. How do you lay yours?
As a "true" herringbone, in an 45 degree angle to the walls. For both small, mostly double (50 x 250mm) and larger, single, herringbones (71 x 284/355mm). Our blocks are 10mm thick and come without T&G. We use a industrial Oak mosaic subfloor first: http://manuals.woodyoulike.co.uk/spaces ... lid-floors
the room is not square, if you look closely, its almost a dog leg! Look at the walls in the foreground, its running at 45 degrees to them, purely because those 2 walls were the longest. The wall with the rad is 135 degrees in relation to the wall on the left. its impossible to have it running at 45 degrees to every wall.
Right you are! (a room where all walls meet in perfect angle must be absolutely rare here. Ton just installed a normal floor in an extension where one new wall run from 7 to 14cm off! - builders!)
Hi dsmart, looks lovely! Looks like you laid this directly onto the epoxy DPM, which I understand it is a bit unorthodox. I've just done the same though. Did you sand the dpm surface before you laid the blocks? If not how did you find the adhesion was to such a glossy surface? I spent quite a while researching which adhesive to use over epoxy, and concluded that only MS polymer types were suitable. Bona recommends that s760 is laid over a slightly textured surface, which an unsanded epoxy DPM certainly ain't! But then if it stuck down well... Dom
Hi Tigger, Yes, a bit unorthadox as you say. The DPM wan't sanded. I spoke to the technical guys at both Bona (adhesive) and Sika (DPM) and was advised that applying S760, directly onto a smooth DPM would be fine, though they both said it was an unoffical view and just based on their experience.
