hey,

I got a job tiling a new wooden house. 2 bathrooms and a hallway area.

Is there anything specail i need to do or use????

the hallway area is 15m2 and has been boarded over the joists with 15mm chip board twice. Its seem sturdy enough,

Do i need to board it again? if so what with? how thick?

If not i was just going to tile over it with flexible adhesive.

any advice will be very very welcomed

thanks

Hi,

Double check that it is infact chipboard that has been sheeted twice with as this is generaly not a common substrate to tile to and not one that many of the guys here would tile onto.

Is it perhaps chipboard over sheeted with ply?

Is the house timber kit or did you mean log cabbin type?

I live in slovenia, so things are a bit different. But yeah its chip board i've seen in.

its a log cabin style house.

Do you think i need to board it again?

I would glue and screw a 6mm backer board such as Hardiebacker or a Wedi/Marmox type board down first if it was me. I assume that because of the double sheeting the floor is completely deflection free?

To be perfectly honest with you, I dont know how suitable these types of buildings are for tiling but I have in the past reccomended alternative flooring to be considered when I spoke to someone a year or two back who had a similar project here in the UK. But then again it is common to tile floors in timber kit houses/ extentions in the UK so perhaps log cabbins are just as suited to tiling as timber kits.

The best you can do is perform all tasks that will help eliminate chances of the installation failing which in my oprion would be a decoupling mat (providing there is minimal deflection) and good quality adhesive as well as ensuring that you use the appropriate fixing methods.

You could alway double check with your adhesive manufacturer to see what there take is on this.

good luck with the job mate

whats deflection?

that a really good idea to talk to the manufatures, maybe that shulter orange would be a good idea.

thanks

When you stamp on the floor does it just thud or bounce.

Deflection is vertical movement in the floor e.g. when you walk over the floor does it sag or bounce at all? Timber floor needs to be very rigid to take tiles as they will not tolerate any vertical movement in the floor and can break or delaminate from the substrate.

The decoupling mat will uncouple the tile from the actual timber substrate and will also bridge over any joints in the floor eliminating the chances of hairline cracks appearing over the joins. It will also give you waterproofing in areas of moisture and wet areas like the bathrooms you intend to tile.

Again, your floor will need to be solid and rigid before tiling commences.
