Hi all, I have been building workshops for a chap who has a vintage bike collection, and we had a local flooring company in . The remit was to provide a durable finished surface to our newly concreted floor, needs to be fairly durable for working on his bikes! They sugested Ardex na and they carried out the work ,rolling on a barely covering primer and next day laying the Ardex coating on. The next day there were tiny like moon craters all over it ,so I called them back and they overlaid it with feather edge. We now have another large 60 square metre concrete floored building which will be used as a bike showroom, so now we are going to do this ourselves. Is ardex na the best product to use for a durable floor which will be painted with good quality floor paint,or what would you recommend? I contacted Ardex after the initial job ,to find out what paint I should use, and they told me that poor priming was the cause of they craters and the NA was not the right product for this type of floor , however the customer is totally happy with the surface after we coated it with two coats of FLAG floor paint. So what do you suggest we use for this showroom floor, Thanks in anticipation ASH
They should of primed it the same day as Screeding it. If the concrete was dusty it should of had 2 coats of primer. I’d say a good screed for the bike area Fball Stopgap 800 wear coat I’d contact them about it Sent from my iPad using Tapatalk
Newly laid is the clue, not many screeds adhere well to new concrete until it has cured to a satisfactory humidity, NA will do the job, air bubbles can be an issue no matter what primer is used and one coat is optimistic.
Thanks Guys ! Good to see you are all willing to give me some valid advice, I will have a word with Ardex as well and let you know how I proceed. If I use a skid or pin leveller for the slc , will it scratch through the primer and therefore break the seal? the concrete was poured about two months ago and roof has been on three weeks ,so should be pretty dry now. Have a good weekend ASH
So if we use the NA it would be better to lay it in two coats,should I reprime between coats, and howlong before you would lay second coat after finishing first coat Ash
