Ho folks...hope I can get some input...

I wanted to make a semi circle concrete pad, but I can't find formica...the last time I did one of these I was a teenager and you could buy sheets of formica that were strong and would bend in most any curve you wanted.

Now the big box stores don't carry it at all...no other types of places around here

What do you guys use now that formica is not available to make curved 8 inch deep concrete forms? Thanks.

Try Masonite, most big box lumber stores carry it, I've even used luann plywood if the curve isn't too sharp.

when I do a search for masonite on the home depot site, it brings up those fake doors...in what form can you find a thin sheet of masonite?

You should be able to find it in full sheets of 4x8 and half sheets of 4x4. It comes in solid and peg-board where the holes are predrilled.

Other options might be that stuff in the plumbing/shower department. It looks to be full sheet masonite but is coated in a white finish. I've used it to make whiteboards for my grand kids to mark up. It's thin, strong and very flexable like masonite but I would bet with the white coated side to the concrete, that it would release very easily.

I think the common name for masonite is hardboard. I haven't looked recently, but I thought the home center stores stocked flexible form material for pouring sidewalks.

Are you checking their website to see if your local store carries the stuff? I've found that their website is particularly poor when checking stock for the building supplies you find the the lumber area... probably way too many items with pricing that changes too often. If you go to the store you'll probably find it... it does work well for curves, but make sure you have plenty of staking and or a low slump mix.

We always use utility sheeting.......depending on your radius you might not even need to relief / back cut to get your desire shape. Utility sheeting is one by (1X nominal in varying widths) in white pine and is inexpensive, durable and with the right amount of pins it can be used by itself. Hardboard is weak and will need to be at least doubled and will blow up when exposed to moisture. I doubt you will find utility sheeting at a big box store.....a lumber yard most certainly. It is also known as roof sheeting in some areas.

You have some good answers here, with diff. options. You should be able to find "Hardboard" "masonite" at the big box stores.

I buy Wisonart at THD and Lowes. That is the brand of Laminate they sell around here, its just like Formica. Good Luck

You can use about anything at the bigbox stores. Thin paneling, that plasic wall material they use in trailer bathrooms. Thin ply was another good one mentioned.
