Hi, I want to lay new laminate but cant be bothered with the mess and stress of taking the old up. Is it poss to just lay it over the old? i know you can tile over tiles, so i thought baybe you can laminate over laminate??
thanks

Ceramic or porcelin textured tile?

Seems so many pros and cons for each, I need hardwearing, german shepherd proof and would be grateful for any advice.
thanks

Hi there

I have a room that is both floorboards and concrete. About 2/3 of the room is floorboard, and 1/3 is concrete (on the edge). Now the concrete is slightly higher than the floorboards, creating a slight dip as you walk over it.

I am going to install laminate using fibreboard underlay.

I realise there may be slight dip and I am ok with this, but in your experiences, would the laminate crack or break in future? I am hoping it does not, especially after using fibreboard underneath.

Thanks in advance

Can a vinyl floor be layed on top of floorboards in a bathroom or does it require an underlay? What kind underlay an thickness would be required. What of the floorboards are even is an underlay still recommended or required?

Does it need to be any special type of plywood? When screwing it down what length screws should I use, how far apart should they be spaced and do you screw through floor board into joist or just the floor boards? Since the floor board are screwed to joist, it would be difficult to locate them plus not enough space as I could potentially hit the screws of the floorboards. The vinyl will be removed every year and replaced, so I don't need it for long term use but currently laying it directly on floorboards gives too much bounce and echo.

Also if laying plywood do i need to leave 6mm expansion gaps between the plwood and walls? How would I cover the gaps since vinyl will simply curve into the gap?

There is no skirting, wall tiles have been tiled all the way down to the floorboard on to a 5mm thick strip of wood. Basically there is a 5mm strip of wood around the edges of the room on the floor boards and the wall tiles have been tiled up to the strip of wood but the wood isn't flush with the tiles in some places it sticks out about 4mm. I'm thinking of getting a stanly knife and cutting the wood fluss. If I lay the ply do I now need to leave a gap between the ply and the strips of wood around the edges or is that not necessary. If I leave a gap then the vinyl wond sit flush to the edges. When I phoned a flooring merchant, he said I needed 9mm ply or is he just trying to sell me something that's going to cost more. Thanks for your help.

I've grid the boards with screws 150mm apart - its a lot of screws! It seems ok but I was just wondering whilst i understand glue used in exterior ply is water resistant the surface of the ply wood clear isnt water proof - it soaks up water. I know I'll be laying vinyl on top but I was just curious to make these ply boards waterproof/moisture resistant is there any kind of sealant that can be applied which wont adversly delaminate the plywood sheets?

When i've dropped water on the ply i've noticed it soakes up water. Does plywood need to be layed on a specific side? I bought two sheets on one sheet one of the sides appeard more smoother than the other. The other sheet I couldn't really tell the difference between the two surfaces?

Once again thanks for all your help. I'm just doing the finishing touches where I need to fasten a vinyl/carpet edging trim along the door. Unfortunately at the juncture between the vinyl and the carpet, the floor where the edging trim sits, there is gap between the floorboards so I'm unable to screw the trim. I was thinking of gluing it down. What kind of glue do you use to glue a metal trim to floor board?

We had a company lay laminate flooring throughout our ground floor about 9 years ago. At that time they installed beeding along the skirting board, as they advised I would need to replace the skirting altogether if i wanted the laminate to lie under it.

However, I now understand there is a tool available that can slice the bottom rim of existing skirting so that the laminate can be positioned under it. How significant a job would this be?

I have three good sized rooms and a hallway to cover.

How many packs of laminate flooring would I need to cover 15ft by 18ft?

We own an old Victorian cottage that was originally built in 1840 and are having an extension built. It has timber suspended flooring. Our builder has quoted for 50mm Celotex but I have seen that they are using 50mm polystyrene. I have questioned this with our builder and he has said that they are having to use polystyrene because it is lighter, and that celotex is too heavy for the old joists. I am not saying that the builder is trying to mislead us, BUT I am interested to hear other opinions/hear advice as I haven't a clue. Everything I read online describes how good celotex is. Thanks for your help.
