First check there are no pipes in the vicinity. Tape over any joins in the floor and plug any vent holes, you do not want this stuff ending up on your driveway. Support the affected area gently from below, do not push up. Remove carpet.
Mark out affected area. Make sure you go right onto solid floor. Drill 8mm holes at 150 (or 100) mm centres in the top ply. Be careful not to damage the bottom ply. Do not drill too close to any furniture/appliances. Mix the resin in small amounts, it sets quickly. We tilted the van a little and started at the low end, but this may not work for you, ours did not need any extra support from below as it was over chassis members
Using a syringe inject the mix slowly into first hole until you feel back-pressure. Do not overdo it or you will end up with a humpy floor! Wait a few seconds until the pressure subsides, remove syringe and quickly plug hole with 8mm dowel knocked in flush with the floor. (our repair kits came complete with dowels and syringes, we cut the dowels in half to give a flat cut ) Keep a bin and plenty of paper towels handy for cleaning up, it is a messy job. Continue untill you have filled and plugged all the holes.
After a final clean up, cover the area with polythene and something like a piece of ply, or some boards, and weigh down with some bricks/ couple of gas bottles/similar. Wait at least 24 hours, longer in cold weather, for it all to harden. Remove the weights and supports and sand off any protruding dowels. Replace carpet.
Ours was an area about 45x160 cm, we used just under 2 tins of mix at £30 each, and it took 4 hours to prepare and inject the area.
hi,delamination...frightening no if you set out your stall and take your time.this is not a two hour job as stated,when you have finished you will know why they charge so much at the caravan repair shop.i have just done ours a few months ago.i will go through the steps best i can.ours had gone in two places,next to the door entrance and next to the sink four feet away.you will find that delamination is where the floor is used most.ie next to the sink and the door entrance.first decide how much delamination you have,ie.2 feet (old school) or 6 feet,this information is required when you go to order your epoxi resin mix.one mix will cover about 3 feet by 3 feet.got mine from barrons £25 for both tins.you also need a large syringe to inject the mixed epoxi resin.this will also sell.also the chemicals (glue) are called apollo 1 and apollo 2.i think the code is A8136.the small tin is the hardener and must be used in the time on the tin.the first thing is to remove all carpets or lino.second(must) tape up all joints and the cowls under the caravan .use a good tape.ie brown packing tape,3 in wide.if you dont the glue will run out on to the ground outside through all the seams.you will not know until you see a pool on the path..third ,support the floor under the van in some way so it cannnot bend when pressure is placed on top,do not push up the floor.you can damage the fittings inside.use wood blocks stacked up just touching the floor on the underside in the same place as the delamination.fourth find a sharp 10mm drill .you need to buy 10 mm round wood to cut and plug the holes,sold in 6 foot lengths.this needs cutting into plugs,half inch long and sanded down at one end to make it go in easy.the next step is to do a test hole,find a place that has no gas pipes on the underside.slowly drill one hole until it only just touches the plywood at the bottom.DO NOT DRILL THROUGH.tape up the drill at this depth,use plenty of tape to stop the drill going deeper than it should.mark out the area of delamination,black marker,in a square grid pattern of 4 inch each way .when finished you will have a large square full of holes to the size of the delamination.ie.3 x 3 feet.clean away all and any dust or shavings.have a large polythene bag ready to put over the square,the glue does not stick to polythene.you need a tin or old pan to mix into of the correct size for size of mix.a clean strong stick to stir the mix.only mix what you need within the time allowed.start at the rear end injecting the holes one by one until it flows out then plug with the wood plug.when finished ,place poly bag over all holes.put a heavy weight on top ie.wheels and tyres or gas bottles.leave for 24 hours to dry.sand down all plugs until smooth.you must wear a mask for the fumes and open the windows when you are doing the job.rubber gloves are handy too.CHECK UNDERSIDE FOR GAS PIPES BEFORE STARTING.wish i could type. thought this may help
------------- the only silly question is the one you do not ask.
found some on ebay Profix? kit, syringe etc its about £23 + delivery i'm guessing 2 tubs as i have 2 areas about under 1mtr square (front of door + front of Kitchen!)
