I used foam for all the walls and the flooring, following the other tutorials on here and youtube.. then did 4 layers of grout, 5 layers or so of paint and another 5ish of sealent. The drying process is what caused it to take so long.
Hmmm i hear of everyone using this Mod Podge but i have yet to track some down in Canada. I assume you live in the states, wondering what our equivalant would be, or what my other options are.
What kinda store do you buy this stuff at? I have checked Home Depot here and i cant find anything that is labeled as "non-toxic" sealer.
You get it at hobby shops like Michaels, AC Moore, Joanns.. ect.. You can probably buy it directly from their website. I think its for sealing paintings and craft related stuff.
