Guys im wondering if anyone actually knows the name of what im about to describe. Its a dark coloured, often purple tinged floor, that coves up the walls. Has straw under it a lot of the time. Its a sub floor i think. Although think it may have been a finish? Im guessing from the 40's? As that when some of the houses in local council estates date back to, and thats where ive found it on numeral occasions. Hopefully someone can shed some light. Cheers
Composition Screeds (Quote) Floors constructed of magnesium oxychloride cement or polyvinyl acetate/cement will be adversely affected by dampness rising from the ground if they are covered with an impervious layer. Unless it can be established that the composition floor is adequately protected against rising damp, it must be removed and the base made good before floorcoverings are installed. If the floor is protected against damp then cracks and small hollows should be patch filled and the whole area skimmed with a minimum 3mm of the appropriate smoothing underlayment. :thumbs
Could it be Magnesite Flooring ?? The following paragraph is from the Floorskills Subfloor Prep fact sheet...hope its ok for me to put this on here... "A flooring material composed of calcined magnesite, magnesium chloride, sawdust, ground quartz or silica, and fine powdered wood waste; Used as a finishing surface on concrete floor slabs. Magnesite is normally red/pink in colour BUT colour pigments was sometimes used. It has wood, sawdust and Asbestos fillers. Very rare to find after 1960. This floorcovering cannot be prepped nor can it be covered. It breaks down with age and releases chemicals that corrode metalwork like plumbing. It should always be removed"
magnasite.. Did you not get shown it on the karndean course Kev? Or the Amtico one? Soft as sh1te stuff, cant do a thing with it etc etc Theres loads of the cr@p in the council housing up my way from the early 80's
It does sound like the stuff. It dents fairly easily too, its absolute s**t stuff. The coved skirting had already been removed on this one, with a floating laminate over the top. No moisture barrier in the underlay, laminate perished fairly quickly from what im told. Now we know why. Decided best state of play was to remove it back to concrete and start a fresh, needed to know what it was called for future ref! So thanks to both of ya :cheers:cheers:cheers:cheers:cheers:cheers
Was shown it at FloorSkills but no I've never came across it before ? Sods law next Job will be loads of it Lol
Yeah magnasite is a bugger, nothing you can do with it always rip it up but be careful as it has all sorts in it like gazhugs said asbestos and silica being two of the worst culprits, damp down and masks etc
