Another question regarding GS foam...

[Berzerker]

My question is this: Am i able to run a flow test on a GS foam waterfall that has cured but was also carved out? Is it ok for water to get in the little bubbles? i just don't want to silicone it first then have to make adjustments afterwards. I am also about to start laying coco husk on my BG but my girlfriend is going to paint some areas to look like stone. The stone areas will be on the waterfall. Should I silicone the areas she is going to paint before she starts painting it?

Thanks for any input.

i would pick silicone or paint.

you can run your water feature for testing... just make sure the g/s is completely dry before you attempt covering it so your paint/silicone adheres to it properly.

Thanks. Afterwards, should I silicon everywhere that is going to be painted or just paint right on the GS. I'm not sure exactly how well acrylic paint will adhere to silicone.

you'll be better off painting g/s than trying to paint silicone. silicone doesn't take paint at all.
