Thread: sealer to use with drylok?

Tweet

hi - i was wondering if anyone uses an additional sealer or varnish after they drylok their props - not sure if its even necessary - but i figured if if i sprayed or applied a sealer after it might plug any holes the drylok may have missed -

thank you-

Dryloc is simply a primer/sealer for masonary. A base for paint. It has no UV protectant, but being that these are props not a big deal,
however a clear sealer like driveway sealer (water based,natural-flat) will give you a better bullet proof weather sealer.
I usually throw a a flat white & whatever paint effects I want on top of the dryloc, then the driveway sealer.....

I've never had any problems with the elements when using exterior latex paints or dryloc on my foam props. I figure if it's good enough to put on the side of my house then it can take being outdoors during October Most my damage or repairs come from time in storage...dings, dents, scrapes and things like that.

Paper mache I use a couple of layers of paint and a spar urethane for extra sun/rain protection.

No problem just using Drylok here either. I've had them out for a total of 60 days (2 seasons) and no problems. I do 2 coats of Drylok.

thanks for the replies - i figured it didnt need anything else...guess i'm too anal - thought about the concrete sealer for uv protection but i guess its overkill -

Humm, never thought of the driveway sealant. I'm still fighting trying to get some painted standups coated. I used cheap craft paint and harsh language will make it come off so they need to be sealed up good. Problem was that the water based urathane also melted the paint and made a mess.

Waterbased urethane ?? you mean poly urethane...? Even with a clear like a water based driveway sealer, the clear can reactivate the paints & pull the paint right off, even without harsh words......
I would wipe it down, sand it lightly, prime it then paint it with whatever. Also make sure your paint is completely dry before next coat, especially clears.
Best thing to do if ever you have the probs your having now, start fresh, struggling thru it will end up as a projectile instead of a project !!

Even "cheap" craft paints can work, it's all about pre-prep (surface clean/primed), compatibility of all paints & (flash time) dry time between coats.

thanks for the info ....is the uv protection a big deal with outdoor props? also will a (concrete) sealer have any negative impact on drylok?

UV additives simply keep colors from fading & the paint itself from deteriorating..... If your prop is just outside for a few days or weeks or even a month, no biggie. Just if it's going to be outside 24/7.
If your Dryloc is dry, any sealer (water based) should be fine. Also lay a very thin 1st layer clear on & let dry as a base then you can add a heavier coat on & the 1st coat will keep things from lifting, heavy 1st coat sealers tend to cause probs.

gotcha - thin coat to start - again thank you -
