:help: Did I mess up using weld-crete as a primer coat?
I jumped the gun on something before reading up on it.
I was talking to a plasterer a few days ago and he was mentioning how he uses weld-crete or plaster-weld over existing stucco/cement to help with cracks, etc..
I didn't look too far into what else he meant by that other than thinking 'this is exactly what I want to use on the outside storage area' since it works great at welding the stucco before recoating.
I figured that this stuff might be worth a try using it as a primer for an outdoor open storage area before painting it.
so, what i did was:
strip down all wood, roof, etc..
power wash walls & floor
patch existing holes in the storage area with concrete patch
applied weld crete on all walls and floor.
I finished that at about 7pm, it was dark but I wanted to finish so that I could let it dry overnight, then paint in the morning.
I got elastomeric paint for the walls, and a porch concrete paint for the floor.
as I finised I thought the bright blue looked like a swimmimg pool, but was glad to have that finished, it dried pretty quick.
I get inside the house for the night and start reading. I find out what I overlooked from the plasterers conversation. that weld-crete & plaster-weld is a bonding agent between existing concrete/stu to new concrete/stucco. :censored:
I think my only option is to just paint over it tomorrow, and time will tell whether I messed up big time or not..
heres a few pictures. Ill post the weld-crete one tomorrow, it was too dark when i finished to take a pic.
Bokeh, I think you may have made two mistakes. You generally can't paint fresh concrete until the PH level drops below what the paint can handle, usually anywhere from a couple of days to thirty or more, depending upon the finish. I'm not quite sure what mistake you may have made with the weld-crete. Do you have that currently as an unpainted stand alone finish, and it can't be used as a finish? Please explain a little more.
the storage area was already stuccoed, and painted about 15 years ago. the floor was also poured 15 years ago, and is untreated.
I patched the holes that were made when I removed the boards that were nailed into the walls for shelving support. I used Quickrite patch for those holes..
I posted a few pictures, the third pic shoes the patched nail holes on the walls.
I didnt get a chance to take a picture of the weld crete coat. But what I did was applied the Weld-Crete to the walls and floor, the whole inside of the storage area is blue from the weld-crete. I was thinking it was a sealer & primer for concrete and stucco. Which I don't think it is.
I've tried googling for terms like painting over weld-crete, and turn up nothing. all weld- crete use is for a bonding agent between existing stucco & concrete with patch or skim coats.
Honestly Bokeh, I would hold off until you contact the tech hotline of weld-crete for assistance. I think they are the only folks who can give you the guidance you need. If you did indeed make a mistake, don't compound it. They will usually have all the various outcomes gamed out and should be able to help you. That's what they're there for.
You're right, I'll send them an email right now just incase they reply with an answer before I wake up. If they don't reply tomorrow, I'll give them a call during their office hours.
I figure that I should update this thread since I've gotten a response from Larson Products, the makers of Weld-Crete.
"You can apply water based paint over Weld-Crete. I'm afraid any solvent based paint would delaminate the weld-Crete"
Since I purchased latex based paint, it was fine to apply it over the Weld-Crete.
I was also reminded:whistling2::
"Just so you know, Weld-Crete is a bonding agent for new concrete over any clean surface"
here is the Weld-Crete coat
two coats of paint applied.
Walls = Valspar Duramax Elastomeric masonry, stucco & brick paint
Floor =Valspar latex satin Floor & Porch paint
Looks great Bokeh, nice job. I'm glad you got the confirmation straight from the manufacuter, as there are some questions only they can answer. You dodged a bullet buddy!
