Timber / Laminate / Floor /Floors/Boards /Diy/Floating

can anyone please tell me what the consiquesnces would be if i didn't put underlay below my laminate? i have new moisture resistant oak laminate which i would like to put on top of what appears to be a chipboard type floor base. any ideas?

Thanks, for providing your know-how video! My husband and have purchased an older frame home that needs a lot of work. I'm now comfortable with attempting to lay down our flooring product! Thanks!

I am installing a lock and click type laminate floor. I am at my last plank and it is at a door area. I spent the whole day and wasted 2 planks trying to install at this area. I cannot tap the planks together if the plank at that area is already pushed underneath the door jamb. Since this particular type of floor has to be angled and then pushed in to lock. Should I redo and start at that wall instead? it is 27 x 13 room.

The is the best demonstration I have seen yet but once I start the 2nd piece in the second row I cannot get it flush in place. It will not tap into place horizontally.

This is not as simple as the video shows for the product I bought.

This video instruction is great. I didnt realise it was that easy and was going to pay someone to show us how. Thanks - i think we may just do it ourselves :) perhaps some instruction on joining etc would be good aswell :)
