New Wagner Videos from Surfaces 2011

#1
From Surfaces this year. There are three.

The Q&A has a question on engineered wood. That is something I've got to address. I have about 8,000 s/f of wood in my warehouse that got VE'd out of a job. I'll have to use great care to monitor that wood before I install it ... some day .... when I can sell it. May buy the Wagner meeter before hand. Does anyone know how Wagner recommends taking the ambient readings to get the EMC? I've seen some scary videos on how hygrometers can get out of wack on ambient conditions.

The Q&A on a PT slab is hilarious!!! I guarantee you most of the audience have no idea what he is saying. I've heard horror stories from S.America where they 'accidently' cut a PT cable.

The Q&A on Gypsum is crazy! Those installers better know that most resilient flooring can't go on Gypsum.

The Q&A on wood flooring RH was interesting - he must have known that the MFMA was going to do what they did re: rH.

The Q&A on joints is helpful. Interesting to make sure to space those tests. I wonder about depth in a slab that has a blotter layer under it... perhaps ASTM should insist on a deeper hole in such slabs.

Thanks for the link!
Right now I'm heading out to install one of those 'expensive overpriced remediation systems' in a hospital, but I'll check it out when I have some free time! Big Grin

EMC table and calculator http://www.csgnetwork.com/emctablecalc.html

Those guys have every type of calculator onsite known to man. Not sure about how wagner recommends taking ambient reading but I take them on top of my Tramex Professional case. Big Grin Like down near the ground cus thats where I work. If you took them near the ceiling would it be the same?

Gypsum underlayments have changed so much in the last ten years... Some gyp based levelers reach 4,000 - 7,000 psi now. These aren't your daddy's underlayments.... Big Grin

Few resilient companies accept gypsum as an acceptable substrate. Usually you are on your own with the Gypsum warranty to cover the whole deal.

My point was that gypsum based underlayments have changed so much in the past 10 years, you should ask the floor covering manufacturer if you come across a gyp-based underlayment. It may be approved.

I had Armstrong (or was it Mannington?) approve one about 5 years ago. Maybe Ray can get in this, but what we think of as gypsum based (chalky and soft) is changing with some of the new polymer fortified products.

I love taking up resilient on gypcrete. Piece of supcakes. Big Grin Unless the guy used some ardex product or sealer.Sad I took out some ceramic once I thought...piece of cupcake...ended up taking out four inches of gypcrete. SadSad

It's nice to be back. After about 30 reset attempts one finally worked. Note to self, write down the password.

Welcome back! Wink

Have you ever worked with LevelRock Quick Top underlayment? It's a 6000 psi gypsum based product. I don't think you'd enjoy removing tile from it. It's hard! Sad

No I have not. Charge accordingly! Who got it on the tile surface?

Sure is great having lots of floating resilient products out there.

Whats the ph of gypcrete anyway?

Good question!! I don't use it, just had it put down for one of my flooring contractors in a building about 6 years ago. I did ask about the project last year and the owner said it looks great. It was in a dialysis area of the hospital so it saw some cart traffic and wheel chairs but no real heavy rolling loads. Mannington vinyl is on top of it. Under it is old glue, some VCT, some ceramic, some stripped plywood. The request to put in the LevelRock was originally denied by me.... I was really leery of using it because it is gyp based and it was going over absolute trash.

But by golly, it may have worked.... Tongue
