How to jigsaw in from an outline to account for carpet over ply
Hi
I am making a false floor for the back of the car, i have traced out the mat as below
Mat laid on marine ply.jpg
rubber floot mat outline to jigsaw.JPG
the mat fits fairly tight up against the cars plastic trims in the rear
I will glue on
Ideal DIY Topdeck Duo Ribbed Charcoal Marine Carpet | Bunnings Warehouse
"
- UV stabilised, durable, insulates and anti-static
- Pool and sea water comparable, quick drying and will not rot
- Resists mild chemicals and fuels; simply clean with detergent and fresh water
- Flexible and easy to work with, can be moulded up and over fixtures
- DIY fibre lock construction that won't fray when cut and shaped"
this marine carpet over it, and run a drawer and fridge slide
i intend to do both top and bottom of the ply with carpet (or maybe just the top and pulled over 50mm or so) -
Dimensions
Width 2000mm Height 5mm Length 25000mm
So should i come in from those traced lines 5mm or 7mmm and how? just by steady hand? or some sort of compass item but one you can fit two pencils to?
Or just trim the current outline and see how it fits then trim bits after that.
Also what glue to use, cheap spray on out of a can or
Dunlop 1L Multipurpose Carpet And Cork Adhesive | Bunnings Warehousethe above product that specifically mentions marine ply, it does have smooth surface, maybe i should 400 grit scuff it.
Also what product to seal the cut sides and? i have exterior paint lying around but can get whatever
thanks

I would use 80 or 120 grit to scuff sand. The 400 grit is more like polishing.

Just get it fitting in neatly, then scrbe around using a 7 mm packer or similar pressed against the surface you want to be parallel to, and mark on the other surface of the packer. Hold the packer and the pencil together ( you could tape them together) and mark all around,including any cut outs. Gets it perfectly parallel and the carpet will fit in neatly. I’ve just done a fitout on a pantech truck for a motorsport enthusiast, and we did sheets of ply the same, came up a treat.

Cut a piece of cardboard and trim it (or stick pieces on) to get the fit/clearance you want. Then you have a template.

but do you mean this

what do you think of the glue suggestion? and how best to lay it out on the board prior to using the v trowell

The Bangood device could give an accurate outline for straight sections and convex curves similar to the table top in the pic above, however your pic of the rubber mat a few posts above shows a pocket and a concave curve on each side of the mat which the device cannot cope with accurately. From the advice above, transfer the mat shape to a piece of cardboard and trim until it is a good fit, then mark out the offset on it with a packer (something the thickness that you want to offset) and pencil, then trim off the offset to create a template that you can use to mark out and cut your plywood.
I used to be an engineer, I'm not an engineer any more, but on the really good days I can remember when I was.

that second idea is exactly what I meant.
The gluing is straight forward, after cutting the carpet to approximate size, including enough to wrap around and under the edge by 50 mm, trowel the glue onto the board then lay the carpet onto it, coating it with glue, then roll the carpet off to allow the glue to set for a minute, then roll the carpet back onto the ply, and roll it down with a rolling pin or similar. Then you can flip the board over and brush some glue onto the edge and underneath to glue the tucks on. Pre-cut the corners first so you’re not trying to cut while the contact is sticky to everything. A few staples will help hold the tucks on too. You can trim the underside off straight and neat later

What Riverbuilder said ^^^
You can get contact adhesive in an aerosol can or a alternative cheap option is to buy the cheapest liquid nails at the big green shed and gun it onto the board and spread with a notched spreader .
Glue the face first then lay it face down and deal with the edges and underside after

thanks again for the replies, after speaking with Dunlop I am going to move to
https://media.prod.bunnings.com.au/a...625?v=dcb5c294
®DUNLOP ARTIFICIAL GRASS ADHESIVE is a high strength all weather adhesive suitable for indoor and outdoor use. With excellent water and heat resistance it will bond securely to a wide variety of substrates and is ideal for installations around swimming pools, balconies and outdoors which may be subject to moisture after installation
It waterproofs within 48 hours apparently.
I just need to ensure that if the carpet can not breathe ie is it stiff backed, can air flow through it, can i breathe through it as a test, then yes leave it for the 1 min described above or until it becomes tacky such that the water and other volatile compounds can evaporate out otherwise it will remain perpetually moist. This carpet is stiff backed and you cant seem to breathe through it easily so it will require that.
beyond this the combo of
- marine ply over mdf
- a waterproof adhesive
- spill resistant carpet
is about the best i can achieve? for when the inevitable jerry can of water leak occurs.

Contact is the best glue for this, just buy a tin of the gel one ,it comes in handy for lots of stuff,and lasts for ages in the tin.

What i didnt ask, is given the marine carpet has ribs, what direction do you prefer the ribs to go.
Left to right or up and down, from the point of view of standing at the rear of the car looking forward to the front of the car.
I feel like left to right ribs helps stop luggage or fridges etc sliding forward and out of the rear of the car? but front to back aids sliding items in and out
