Got a customer ( a mate ) who is converting his old shed which is connected to his house into a hobby room. The sub floor is like a garage concrete floor. He wants it screeded then like a power floated finish or something similar. Was looking at stopgap 800 wear coat or 850 exterior then a coat of stopgap seal. Or Screed with a cheaper screed and then mapei prim grip so left with a grey floor like in matts old training centre. Anyone done anything similar or any ideas?
As you know daz, prim grip works very well but you have no chance of cleaning it. What does work well is a normal smoothing compound like uzin , fball etc and then a buffing machine with a 100 grit pad on it. Will give you a high gloss finish. Basically your polishing the smoothing compound.
I thought the standard screeds were designed to take a floor covering and not hard enough to be exposed to wear? .....or is it okay for light foot traffic?
Correct, all depends on how much wear they would get. The stronger the compound then the better it will wear.
I have actually polished a bit of 300 ( I do things like that) with diamond grits down to 3000 gr. It's looks pretty good but just not very scratch resistant. I always wondered if it the surface could be acid stained and hardened with an epoxy seal. I didn't follow it up as I think acid stains need lime ( as you find in concrete) to react with.
I have a set of diamond 5" pads you can use on a variable speed sander. I used to use them for polishing the edges of porcelain tiles instead of using trim and I made skirtings and nosings out of the tiles. Trouble with that is you rarely get porcelain tiles now that are the same material throughout ( conglomerate tiles?) so you don't get the same effect
If your mean Fball seal, As far as understand it stops the compound from staining from water spills etc. I presume it also give a wear coating also like a pu coat you have on karndean etc. I dont know enough about it daz.
