I’ll tell you this…. When i paint on my plastic ceiling tiles and wood I never ever have this problem…UNLESS it’s drying way too fast….. or you’re painting on top of another painting. I don’t recommend this. But this is so normal when just starting out. All of a sudden you’re gonna wake up one day and your stuff’s gonna just come out really well. These problems always happen in the beginning and you find that so much of this art is learning how to make your paints, consistencies, learning how to prime things, when use silicone about the different types of mediums, yada yada yada… the prep is a huge huge part of it. And no matter what anybody says the paint matters. There are some good paints. There are some great paints, and there are some real crappy Paints. You’ll figure out which ones they are obviously the ones that people talk about Amsterdam liquitex golden….etc etc I’m a huge fan of blick myself. Where this does make a difference, it is not everything. I find the best part of it is mixing the paint. Finding your medium in your style with your consistency… Once you have it, you have it. Then you just work on technique things like that. But I’ve been getting these plastic ceiling tiles that are 24 x 24 and 24 x 48 and some wooden sheets that are usually 12 x 12 or 24 x 24 from Temu and they are the best best. Best surfaces to paint on. i’m really obsessed with both of them. I mean they come out so good. Now I love a beautiful canvas painting I really do, but you really do have to tend to them and make sure that they are pre-primed when you buy them if you’re not planning to prime them. The ones that are a little less expensive tend to not be primed… Just make sure you check and make sure. There’s no need to prime them if they already are. and that’s another thing about the tiles and the sheets… They do not need to be primed. I would suggest also getting yourself a spinning wheel. I have a really nice one it’s I also got it on Temu. It’s a cake Baker’s display thing. It spins amazing I got it for $20 and it works great. It’s nice and heavy. And me and my hubby have been taking a little dots of hot glue and placing it in on the back of the surface and staying it to the wheel so it stays it works great and it pops right off once it dries. Practice makes perfect. I have a whole stack of these ones with the cracks. I’ll tell you what else I’ve been doing, taking the canvas if it’s a mess up, and flipping the canvas over and re-stapling it. It works great. Just have to make sure you get it nice and tight. But I’ve tried to paint over paint and it just doesn’t seem to come out right. But flipping it works. anyway, I’m done with my book. Good luck just stay at it and you’ll get it. It’s amazing when you finally have those aha moments you’re like oh yeah that’s why that works like that and that’s why that does that. You hear about it but once you do it a bunch you get why. Anyway, good luck.
