advice on subflooring

[ereader]

hi
i have bought a old house and am trying to restore it to it former glory and have order multicoloured slate for the floor.
when i took the old kitchen out i found that the floorboards were rotten so decided i was going to replace them until i realised there was concrete underneath with timber beams set in it. would i be ok to latex over the top of the concrete and beams or would i have to remove the timber beams first. the concrete has blackjack over it also so would it be an idea to reseal it.

any advice would be much appreciated

Take the beams out. If they are rotten, they are damp and if you just latex over they will begin to dry and that could lead to dry rot which is a fricking nightmare

Thanks for your quick reply... Would it be best to put a quick drying post mix in first and should I put some sort of sealant on the floor as I'm not sure it has a membrane as it's been blackjacked originally?
