even my patchguy who has been patching for 20 years told me hes never seen the mud react like how its doing for these two houses. this all leads me to believe the mud has a just seems like theres no adhesive or glue in the mud. These are fairly big houses.and each house is experiencing the same problems, and were completed in the exact same time, roughly a week apart. One house is 3000 sf.and the other one is near 6000 sf. (oh btw, in this house.the paper tape itself has NOT CRACKED.just the mud alone - food for thought.)īut ALL of it? EVERY sheet? im talkin two big custom homes here, with PERFECT horizontal cracking (moreso blistering - paper tape is NOT cracked) in 99% of the house. Thanks guys, im sure ill hear from someone soon! quickset alone, and spackling, whatever just doesnt seem to do it - cracks always return.however, this weldcrete seems to be IT. What ive done with these cracks, is have my patchman dig out the crack, forming a V-groove.with whatever tool he wants (he usually uses his own car keys), then i have him take a paintbrush and apply it inside all along these grooves.making sure it gets in there and builds up inside the crack.įrom that point, we let it dry for an hour or so (more if we can), and quickset over the patch to texture it (in this case, im talking about a hand textured house.spray textured house, you can do the same procedure, but anyways.).Īfter the quickset dries, i then paint over it with hamilton prep coat.just to get the two substrates to a level finish.in this case, was a smooth pool troweled hand texture.so, perform accordingly to your texture of course.Īnyways, this SEEMS to be the golden product in situations like this (knock on wood).īut id love to hear your guys thoughts on Weldcrete for cracking.if you have tried it, or will try it in the future.Īgian, the main reason i use this product, is for the cracking NOT to come back since its such a strong bonding agent. so far, Weldcrete seems to be the key for that. The main thing im concerned about of course, is for the cracking NOT to come back. for those of you unfamiliar with the technical name, its that 'blue stuff' that looks like paint. this stuff is used to glue freakin concrete together, so its definitely strong. i strongly feel that the mud we used was defective as well, of course the manufacturer will never own up to this, or even the possibility of it.which is complete chicken s-t if you ask me.Īnyways, what ive been doing recently in situations like this, is using Weldcrete bonding agent.

settling definitely may be to blame PARTLY for it, but not 100%.

I've had perfect horizontal cracking on the walls AND ceiling of this custom home we finished - it looks like an earthquake disrupted the whole house, its THAT bad (which leads me even more to blame the mud). I've had some issues with getting bad pallets of mud recently (that may be a whole 'nother thread and topic in itself).
