Sorry to sound harsh but I prefer personal opinions on how people have carried out this task. I do appreciate the projects page but as its a forum I like questions and answers
[quote="desperado"]Do I need to pva the wooden floor first before laying carpet tiles?? They are the bitumen backed type of tile. Also should I use spray can adhesive or the ready mixed glue??
Strongly suggest carpet tiles should not be fixed to floor with adhesive.
My preferred method, which I have used successfully many times is to first lay 3mm hardboard sheeting, coarse side up, on T&G wooden floor cutting to size and securing with PVA and panel pins or staples. Ensure pins and staples are shorter than T&G thickness so as to avoid clashes with water pipes or wiring.
Carpet tiles when laid will bed-in to the coarse finish of the hardboard and lateral movement is prevented. Tiles can be removed and cleaned or replaced as required, which would not be possible if glued down.
I know it's a pest, but i would recommend putting harboard down first - soaked overnight and pinned every 150mm with more at adjoining edges (get bq to cut into 1200mm squares - easier to handle). Normally these go down rough side up, but as you are sticking carpet tiles on, smoothside up is better. Leave overnight to dry.
reasons for putting harboard down - creates a better/smoother surface and will hide floorboard cracks and undulations; have you ever tried taking up glued down flooring? absolute nightmare!!!
if bitumen backed, then adhesive not required since i thought that the idea was that bitumen will soften at room temperature and adhere.
