I used a rubber mat sold at Tractor Supply and sold by the foot. http://www.tractorsupply.com/tsc/product/rb-rubber-multi-mat-rolled-rubber-1-4-in-thick-sold-by-the-foot?cm_vc=-10005

Curious, did you do a moisture test of the slab before putting down th RB? Reason i ask is i poured my slab in May, pressure washed it in July,but the calcium chloride tests I have done since then show my slab is still releasing too much moisture to apply RB

It is a 4 ton R22 split system. The compressor sits outside and I suspended the air handler and condensor from the ceiling. The condensor coils have a 3/4" pvc pipe exiting at the bottom that I connected to a vent pipe. From there the condensate goes into my septic system. Here is a photo...

I started a 3rd test and this time I made sure it is sealed to the surface. In addition to the dome's sealer I used some AC foil tape around the dome's perimeter. I do have my 42" fan running constantly along with my AC. It is the only way I can keep the humidity down, short of buying a...

When they were trowling my slab leaves were falling and the helicopters trowled them into the surface. I have chipped out close to 100 of them and now am wondering which type concrete patch I should use to fill these. Some are at least 1/8 inch deep. Is there something i can just pour into...

I was not aware of that. Thanks.

The test kit had a dome that seals to the floor. Was definitely a good seal as now i am having to really work to get that seal goo off my pristine surface. Thanks for the comments/replies everyone. I think i favor the idea that the water from my pressure washing has been trapped and is...

I was hoping that my AC would be enough of a dehumidifier, but is only getting the humidity down to 50%. If I did the math right, for my 1500 sq/ft with a calcium chloride test emissions reading of 10, that is 1.85 gallons of moisture/water coming from the slab every 24 hours. Sounds like a...

They laid a plastic sheet on top of sand so I would like to believe I have a decent moisture barrier under the concrete. Radix2, I didn't test before pressure washing so I don't know how moist it was before pressure washing.

I am about to apply Rust Bullet on my new (several months old) concrete slab. I used a diamabrush with water and followed with power washing. After one week of running the AC to help dry out the building/slab I started a calcium chloride moisture test. After a three day test interval I pulled...

I installed two rows of 4' 110V led tubes in my 30x50 shop. Total of 12 tubes in each row. Total draw to light my entire shop is just under 4 amps. Bought these led's and these connectors off Amazon. The connectors shipped from China so those took a while to get here. They are fairly...

100 amp is fine...as long as your compressor doesn't kick on while you're welding and the AC is running. But maybe you could just turn off half the lights before you start. Or, go with the 200 service.

Truckmaster, I found something called Speediduct. Is that what you are talking about? http://www.castel-engineering.com/en/new-speediduct-starter-kit-183.htm

Thanks guys, I like the pvc idea.

I am looking for ideas for the best way to run lines from the inside of a metal building to the outside. I have a 30x50 metal building and am installing an HVAC unit. The unit will be suspended inside from the ceiling, but I am not sure about how to run the two refrigerant lines, propane...
