tile over hard wood floor

hello folks, im trying to decide what the best way is to tile over hard wood floor, one option i have got is to lay a layer of bitumen over the hard wood as a water proofing membrane (to vaoid the tiles from cracking over time due to flexibility and humidity of the wood) and then adding adhesive to lay down rustic clay tiles.

im hesitant because ive read that bitumen will cause the adhesive to crack and the tiles would crack as well, contradictory isnt it?

is there any other way of doing it?

thanks for your replies

 

What exactly do you mean by "hard wood"?
Whats below the hard wood flooring?
Is there any damp present in whatever room the job is in?

On the face of it, your proposition is not a good idea for a few reasons.

 

what would they be ?

 

Why not just seal the wood with SBR or similar and then use a decoupling mat (eg DITRA mat) before laying the tiles.

 

thank you for your reply, can you please write down what SBR means and not just the acronym, im not familiar with those inicials...

 

by hard wood i mean a floor that consists of slim wooden boards - a little slimmer than 3 inches (6 centimeters) over a system of wooden beams and bars, theres no damp, the wood is old and dried out and not exposed to water

 

Parquet perhaps?

 

yes, parquet

 

SBR is Styrene Butyl Rubber. It is often confused with PVA as a sealer./primer Unlike PVA it does not re-emulsify when wet. Tile adhesive manufacturers often produce their own primers and will probably recommend those with their own adhesives.

I wouldn't want to tile over a parquet floor. In the old days they used to use a black bituminous adhesive to glue them down. In time the adhesive fails and the staves become loose. Nowadays they use a different kind of adhesive but if any of the staves become loose you are going to have problems.

In the following link, the advice is to rip up the parquet.

Sorry, I am guessing that is not what you want to hear.
