primer which one or is it needed.

[cynic]

50m2 limestone floor to be laid on a sand /cement screed .Going to prep floor(put the builders screed right)using mapei renovation screed,couple of small areas of wood to go over very solid ,builder has screeded up to and round them(only about 4m2 in three areas).
what primer if any would you use in this situation if any,screed is fully dry.

 

[Brian the Tile]

what type of wood are we talking about in those small areas,and personaly i feel no need for primer

 

[Brian the Tile]

sorry i mean on the sand & cement screed

 

[cynic]

The wood is floorboards, but as i said they have been screeded up to and round and feel almost as solid as the rest of the floor.
I have spoken to the supplier of the renovation screed ,they have recommended mapei eco t does this sound right.

 

[DHTiling]

So have you not worked with stone before..?

 

[cynic]

Yes have worked with stone ,but wont to make sure using correct product to prime under renovation screed.

 

[DHTiling]

What are you going to do where screed meets timber..?

Eco prim t should be fine although there are dozens of similar primers. You are best to stick with the system from the same supplier if possible.

How do you know the screed to be full dry?

 

[cynic]

As i said wood is in 3 small areas around floor,and does seem solid,so the idea was to go over it will the screed then lay the floor.
the screed was approx 3 inches thick and has been down 3 months, inside a new kitchen /dining area.

At three months it is border line if it will be fully dry or ot. 75mm takes about 90 days but we have hhad some of the worst drying weather this year ever so I would double check it personally.
