I have a large board 4x8 and I've used 2 2x8 pieces of blue foam for it however I am currently not sure how to get the seam between them to look nicer, I've already spray painted the pieces separately, any suggestions?
What are you going to cover the table with? Flock, plaster, paint only? Are you going to reinforce the foam at all, or just glue it together?
ok well judging by this ^, im assuming you dont care if the pieces are together so what i would do is probably glue it as your first step, you can reinforce it, its never a bad thing and it is really easy, just take a few of the long wooden skewers and stick them in. with a 2' by 8' maybe stick one in every 2', so there would be 3 skewers (one at 2', 4', and 6'), then use pva glue to glue it. super glue or stronger does melt the foam and will most likely make it weaker. so after that, you should be glueing on sand of som sort, to cover the whole thing, this will get rid of the crack with sand and should be completely level. after that, you will want to water down some pva glue, (warning you will need a lot of pva glue for this entire project, one of those big containers, of it will be good.) fill a little plastic cup with some glue, then add a little water and mix, then add a bit more, and mix, do this until it is about the viscosity (flowiness) of maple syrup. then take a big brush and paint the whole table with this. you might need 2 or 3 cups depending on the size of the cup you used. this will seal the table so the sand will stay on as well as making the foam not melt when sprayed with primer. let it dry for about a day or 2, dont take any chances, if it feals dry, give it another half day. then after this it will be a little shiny, but you will prime it black then paint it how you want. (it should just be sand at this point. ) then when thats all good and dry, add some grass flock or whatever else, and then put on some terrain, (dont glue it but im sure you knew that.)and voila. a great gaming table that is strong, will last a while (if you sealed it well which shouldnt be very hard) , looks great, and most importantly, (in terms of this topic) no line down the middle.
oh thank you some1, that reminds me of another fairly cheap thing you can do to keep it strong, is glue it to a 1/2" thick wood plank to the bottom the covers it all, so you will need 6' by 4' of the wood. i forget what the wood is called, but it is very good for this, when i remember what it is called ill post what it is called.
ps, the wood underneath would just be if you plan to move it around a little, if it is going to stay in the same place, for as long as you need it, there is no need for it.
ok i just remembered, the wood that you could use to support is called partile board, or osb board (same thing). its the one that you see all the wood chips pressed together. its cheap and fairly fast to do.
working on terrain pieces this evening nothing quite done yet, curious what I should use for clear water effects though? I tried out some stuff you heat up but it EATS the foam so badly, tips would be helpful, thanks
ok well i do have a few things i know of off the top of my head for water effects,
1. water effects. it is the most obvious but i assume you know of it and want a cheaper solution than having to pay like 50 - 100 $ on it to be able to cover whatever you want it to.
2 mod podge. this is a type of glue but it dries clear and glossy. exept then it will take a bit more time because you have to do it in small layers, probably 2mm or less each layer, this will take long but it should work if you have the patience.
3 white glue. basically the same as mod podge but easier to find and cheaper, although it is a bit weaker, but if you just pput a bit of ard coat on top, (paint it on as you would a model.), it should be good
ok so i would like to see pics if you got em. lets see it before the water and after.
I asked for the water effects for pieces of terrain actually, making a "bio-transference" chamber and for the top I cut out an area for "water" and i planned to have crystals in there in about the middle of it like a power conduit for all the bio energy coming out. I am working on terrain atm more then the board itself I haven't glued it down yet or put stuff around it to stabilize it a bit more but will work on it today
Here are some more pictures of the terrain my friend and I have been making, first ones ever using the sticky guide at the top of this forum pretty much, then winging it for a lot of trial and error. Still haven't fixed the actual board yet probably will not do sand not sure how to get it to not be so messy because I have to turn the board on its side to store it between games.
Keep in mind this is the first terrain we have ever made, and I know myself I can not paint worth crap so don't expect too much for the painting skills lol, however still pretty proud!
This last image here is the top of the bio transference thing basically planning to put some crystals into it, then add the water effect with dye in it for a slightly green haze ,then decorate the outside of it
