floor flex

[TheWrightTiler]

only option id use would be to lift the boards
stick a baton against the concrete edge and screw it to the concrete using a glue to hold in place also

then re lay the boards and screw to the baton

again using expansion joint where the 2 substrates meet


filler foam is good and sets hard just be careful not to go daft as it does expand but can be cut with a chisel if it goes proud

Bugger already cut boards and started to fill with trumix then was going to fill up and go over with sand cement mix. Saying that the concrete edge was all over the place. Will have to see how it sets.
In the other part of room there are vinyl tiles and stuck solid, cant get them up with my SDS either was wondering whether a clean and slurry coat over would be suffice. Here are some pics.

Thanks Steve.

What do you intend to do with the manhole cover?

Its flush with the floor and sealed with no movement so was going to use flexi addy over this part only with normal over the rest.

BAL SPF will go straight over secure vinyl tiles. If they are rough you could skim over with BAL Acrybase first.

Is that without slurry coat Grumpy and are zinc coated screws ok for the backerboards,

Thanks Steve.

Yes Steve, no slurry coat. Not sure if zinc coating is resistant to the cement in backerboards but I would imagine it is. They use zinc to inhibit corrosion on steel exposed to the elements, but I would be guessing if I gave a resounding yes!

If you are to go over those vinyl tiles make sure they are degreased and prime with BAL bond Sbr and tiled within 24hrs.......

Hi,

for a sand cement screed do i mix 4to1 building sand to normal blue circle cement and leave to dry before going over with concrete or will sand cement screed up to desired level do?
Know how to pick my jobs for a beginner!

Cheers Steve.

 

[White Room]

No building sand you want sharp or river washed mixed semi dry as you said 4-1 to a maximum depth of 75mm. Do the concrete first then screed if thats an option for you

 

[DHTiling]

Use rapid setting cement as well this will speed up the curing process........
