Waterproofing Dome
 
Hey gang, i plan on covering the dome this weekend, basically wrapping the dome with 6" of CF blanket, then covering with stucco. So i need to waterproof the dome and came across this product Seal-Krete 5-Gal. Original Waterproofing Sealer-100005 at The Home Depot. I guess you just apply it to the finished surface to the stucco. What do you guys think about this.

No one?

Also do we use the stucco with fiberglass shards mixed in bags?

I think that the reinforced stucco would be a good idea. I'm strictly old school, and relied on my ages old memory of mesh wire. It is a pain in the ass to fit mesh to a dome. Though it can be done.

I think it was David S. who reccomended the the fiber reinforced stucco. I'm not sure that shape is important to you, but unless you fit it very carefully, you will end up with extremely varying thicknesses for your blanket layer.

I think that 3" is enough, but then I used vermicrete to true up the dome before applying stucco.

Just Sayin'

Edit,
If you are intent on waterproofing, think about a vent of some kind at the apex of your finished dome.

Here is a video of someone using fiber glass reinforced stucco at about the 4:35 mark.

Be careful, don't just use any old fibreglass, it needs to be AR (alkaline resistant) there are tons of different fibres available. I use plastic ones for the outer shell because it does not get too hot, but you can get steel in various sizes and thicknesses as well as stainless steel.go to a concrete supplies specialist.

Thanks man. If im not mistaken ive used a premixed stucco with fiberglass before. Ill have to check and see about that. As far as wire mesh goes i have stucco mesh that is softer, its not as hard to work with, the wires are thinner so that shouldn't be too hard to work with.

I was also thinking about mixing some Rapid Set with the stucco, so that it dries faster, it may even help out by not wetting the insulation too much, or even drying faster? just a guess.

If the product you use contains Portland cement you can enhance its strength by keeping it moist for a week. I wrap mine in cling wrap for a week. If your product is acrylic then this curing does not apply.

Thanks David

I dont think ill add waterproof additives with the stucco so i will allow the stucco to dry fully then apply the elastomeric water proofin paint at the end.
