subfloor for solid bamboo

[peterf83]

Hi,

I am looking to install a solid bamboo floor in my living room and hallway, I have ripped up part of the old floor and was going to use a latex self levelling compound as the floor is not completely level. I was then going to glue the bamboo onto the newly levelled floor.

However.... I have just had my builder round to quote some other work and asked his advice on the condition of the floor. He said that I couldn't latex the floor as the floor has glue or something that would have been used to glue down vinyl. I have attached some pictures to show you.





I can't have a floating floor as the wife wants a continuous flow from the living room and a clic clac type wood will cause me problems getting through the door way under the door frame.

I am prepare to put down an 18mm plywood onto this subfloor and secret nail onto that but it has been suggested that it not be a good idea. I am not sure why though as this would be the process if the subfloor is floorboards.

Any advice would be much appreciated

As a DIY'er you would be well advised to float the floor.

Depending on how the hallway meets the larger room you might "have" to change direction anyway?

Any good floorlayer knows how to blend-in a transition, a flow thro, or a change of direction with or without a transition strip/bar.

The thing is with what you propose, every milli of raised FFL can cause further knock-on difficulties.

The old black adhesive appears to be bitumen. No special prep is required to SLC over it, or to spread any other adhesive over it.

Why do you consider your solid floor to be uneven?
Over a 1500mm straight edge how many milli is it out?

To need to find out is there a working dpm under the concrete?
How old is the house or extension?
