Some advice please.

I'm just removing some old safety flooring in preparation to laying 2mm polysafe standard.

The old stuff is coming up ok but in places taking up the old screed. So at the moment I've got areas of no screed and areas of old adhesive.

I was planning to prime with diluted 131 and use Ardex na but do I need to remove all the old adhesive or just give it a scrape?

Thanks.

 

if you get most of the old addy off with a scraper, and the old screed is solid then you should be able to go over with na imo

 

Get some Ardex p51 mate, great stuff.

 

yep, but nobody listens to me..

 

i'll second that
Just switched to 51 from 131 and its great gear!

 

Won't 131 do the same then?

 

speak up mario, cant hear ya!

 

See,....

 

either will do but who am I.....

 

If you already have 131 and you want to use that you may aswell but as your using Ardex product their primer I'd really worth trying

 

yeh, it should do, but i been finding 131 a bit rubbery lately and peels off etc (like copydex on your hand etc)
tried 51 and its solid, have some eco prim t to try out as well

 

I actually prefer Eco prim t mate, sets completely different to the other primers I've used.

 

use it all the time

 

I do have some eco prim t as well so I'll use that.

Many thanks for all your prompt replies.

 

Na is a soft screed when set but does set quick
What's the area to be used for?

 

It's toilets at some offices.

 

Na will be fine for that

 

Was doing it on Monday and don't have the 51 which was why I was going to use one of the others.
