Tiling on asphalt floor

[darreny]

Is the any need to pva the floor first?

Wouldn't hurt however the right tile adhesive is more important. I would go with a flexible rapid set adhesive. I prefer BAL but there are others on the market.

 

[darreny]

Yeah I have the right adhesive, it's for the hallway so with coming in and out its the pva drying time I was concerned with

 

[Maccapacca]

What do you mean by asphalt?

 

[darreny]

Don't really know what to say about it as I don't know anything about it

 

[Maccapacca]

Maybe screed?

Either way I'd be tiling to Ditra matting.

 

[wazza300]

You mean vinyl floor tiles which have been stuck down with tar? Or bitumen

 

[darreny]

Thanks, I'll look it up

It's about 1/2 inch thick and dark in colour, house is about 50yo. I was always lead to believe it was internal asphalt

 

[Maccapacca]

Interesting, I'd assume it's ground floor? I'd all most certainly not lay it without ditra matting.

 

[darreny]

Yeah it's ground floor of house, gonna do a moisture test tonight

Yep, that's what it'll be. Used over concrete floors to level them and create a waterproof barrier.

Seems to be conflicting advice on whether or not you can tile onto it. I'd ring the manufacturer of the tile adhesive and ask them.

I wouldn't tile to anything other than cem board or ditra matting

I'd be inclined to go for the matting as others are suggesting it is not a significant cost and should ensure durability.

I had this in mine, the terracotta tiles were fitted directly on to it, any damp just evaporated.

If you want to use glazed tiles instead then you'd probably need to seal it

Around the 50s Mastic Asphalt was also commonly used to cover the flag stone floors in 19th century housing.

According to BAL every one of their adhesives is suitable for Mastic Asphalt:

Wouldn't that still leave the question of what adhesive to use between the asphalt & matting?
