My wife and I building our own home and are at the point of damp proofing. Any opinions regarding the difference in quality of the job between these two? Materials for a brush it on (primer coat and finish coat) do-it-ourselves job will equal the cost of a professional spray-on job with a 1 year warranty.
Any opinions on this? Is one a lot better then the other?
Thanks for any advice, John

is your foundation poured concrete or block...?
who's doing the prep work.. ie: snapping ties so they break back where they are supposed to.. 1/2" inside the wall?
what's the prep work included ?
*Yup, prep work is included; breaking off ties and patching them. Its a poured concrete foundation.
*if they'll snap the ties in & out, properly, and patch the holes....then it's hard to beat...also... you can always give it a 2d coat if you don't like the results...we usually patch with plastic roof cement (asphalt )i'm always cautious about the prep. work... it's hard to go back and do it right after everything has a coat of foundation sealer on it..so we usually do it ourselves...
*JohnG, I'm not sure what you are willing to spend, or what type of soil conditions you've got to deal with.If there is any way to swing it, you may want to spend a little more and go with a better system than just asphalt. A one year warranty isn't much of a warranty, and it's a lot of work to fix if you get a leak down the road. Look at rub-r-wall or marflex coatings. They are both much better, actually waterproofers not damproofing. They will cost more, but it's like everything else. You get what you pay for. Rub-R-Wall # is 1-800-860-7721, I'm not sure about Marflex, but a search on the internet should find them.
*Thanks for the advice. I think we are going to go with the professional spray on option. The price is right, and that way I'm not critical path for french drains, backfill, the suspended slab installation, etc, etc, etc,Opps, hadn't seen the other reply when I wrote the above. We are building in a fairly wet area with a high clay content soil. Before starting our constuciton, we had a complete soil assessment done by an geoengineering company here in Salt Lake. They made several recommendations regarding our site (and we have followed them all). We asked them about this, and they felt that damp proofing was sufficient for our situation, and that water proofing wasn't necessary. Thanks for the advice today. My wife and I are contracting this home ourselves, so I may very well be back with more questions.John
*You may be all ready planning to do this - but use a porous backfill.A couple hundred yards of a bank run sand for backfill will allow the water to pass straight down to your footer drains without much opportunity to get through the damp proofing.Bank run sand runs $6-$7 a yard in Southern Michigan.Terry

I've had good results with it on stucco.
