Removal Or Encapsulation Of Asbestos Mastic

Make sure all mastic surfaces are fully covered with Bean-e-doo. The safest way to confirm the presence of asbestos under your flooring is to hire an asbestos contractor. I think I need an inspector, I have called around to find someone who can test the air in my house. If the tiles were both damp and intact when they were picked up, then there would be minimal exposure. The middle picture is the cutback after 1 thin coat of the feather finish.

Also, consider that as long as the asbestos is still in the building, it will likely need to be removed if the building is demolished down the road. I did the entire area twice because part of it was going to get marle tile and part was going to get epoxy paint. Ardex SD-F definitely seems to be the most frequently recommended product if I do not want to remove/scrape the cutback. All the other products require you to remove the cutback with a cleaner and use the skim coat over the residue. Hello everyone, I am putting new kitchen/family room flooring in the house my parents built in 1961. The one difference is the was put on a pressboard which is still sound.

Evaluating Solutions: Abatement Vs Encapsulation

If you put tile back down the you will have to have existing tile taken up by EPA or qualified tech. So our plans are to carpet all of the downstairs, and I’ve read a lot about sealing it, which is what we’re thinking about doing. Rusty i understand your thoughts on covering them up, but as Main6 says, the tiles are falling apart, I assume from past water damage. I just want to get these out now, so as to not need worry about it in the future. Of course this is a concern of mine and I want to just get rid of all the VAT tiles. I spoke to someone at the Philadelphia Asbestos Control Office and they mentioned that as long as they aren’t in tiny little pieces, i can drop them off at the upcoming Hazardous Waste dropoff day.

  • If you removed so few tiles, I can’t imagine that you would have anything to worry about.
  • Lok-Lift is by no means the only option and may not be the right fit for you.
  • Most flooring systems are strong vapor barriers, and as such, strong odor barriers.
  • I’m a pilot, so most of my background comes from my family.
  • “Site surveillance technician” means any person who acts as an independent on-site representative of an asbestos consultant.
  • This means Pine Sol (or other such cleaner and a stiff brush and GENTLY scrub to get the dirt off…Wear a mask as even just the dirt from 35 years will be nasty.
  • Burnishing or dry buffing may be performed only on flooring which has sufficient finish so that the pad cannot contact the flooring material.

WNY Handyman has been renovating property since the mid 1990’s. We have done a number of renovation projects over the years and often share our experiences or renovation techniques. We have been in the business of flipping for fun and profit and provide advice based on our experiences. Our site is geared toward encapsulate black mastic the weekend warrior and the DIY’er. However, it is our experience that many “professional” contractors could use a little advice now and then. The only reason I said at first to get it out of there is in 15 years your new flooring will be worn out and now you have it glued to the bad tiles as well.

Asbestos Abatement Costs

😉 Just keep it damp so nothing becomes airborne. Wipe stuff down with a damp cloth and use a mask. If you vacuum up anything make sure you use a HEPA filter to avoid recirculating it back into the air. In my line of work we have to have asbestos abatements done on our facilities if they come back positive. In the training I’ve had in my secretary position, I know that asbestos only is an issue if it becomes friable.

When I recently pulled up some engineered flooring in my bedroom, it became abundantly clear that it was laid down primarily to cover the strong, strong odor of cat urine that was soaked into the original floor. If odors are your only concern, lay down 35lb roofing paper, then your flooring, and you’ll be fine. I understand not to cut, sand, grind, etc. the cutback as this can make dust go airborne. I wet it down and used a rotary chisel to peel everything up. I used a floor scraper to scrape the cutback down to a shadow and tiled over it with a good modified thinset rated to go over cutback.

Oh well, I’ve been going through the deciding process for a long time, and I’m focusing on getting this job done RIGHT. I’m going to try verifying with the urethane glue manufacture that ARDEX is recommended for encapsulating the cutback adhesive. b) If you glue your floors down and experience a leak in your radiant heat, you will have to tear up your floors compared to unclicking your floating floor. I’ve done engineered hardwood floors in remodeling jobs and have done some research on which flooring system would be best for an Eichler with radiant heat and on-grade concrete slab.

Homes built in the 20th century commonly used black mastic as their ceramic tiles adhesive. They also used other flooring materials like linoleum, among others. For this reason, if you try to encapsulate asbestos floor tiles so that you can install a new one, you will come across Black mastic. If you’re planning to renovate or remodel but find yourself confronted with black mastic flooring tiles, you need to pause and reflect.

What Is Asbestos?

Multiple passes may be required, allowing time between passes for dissipation of the solution into the matrix. Full saturation is achieved when the ACM will not absorb any more of the encapsulant into the matrix. Coverage, depending on thickness and porosity of the material, can vary between 50 – 75 sq. Half my basement was “finished” circa 1959 (~500 sq ft). I had 9×9 tiles, had them tested, came back as having 4% asbestos.

As a polisher, this type of abatement is harder to deal with. First, you must explain to your customer that the resulting finish will be exposed aggregate. There is no way to use the existing slab and not expose the aggregate after the paste cap has been removed.

After the abatement guys took out our asbestos tiles there was a black adhesive left. Any idea’s on either how to get it up or can I glue my new wood flooring down onto this? I have a slab house and this stuff is on every square foot of the house. It is hard as nails and isn’t going anywhere when scratched or sanded. The most infamous vinyl floor tile is the 9” x 9” variety which was a popular size during its peak and is typically associated with being an asbestos-containing material. The more modern 12” x 12” vinyl floor tiles may also contain asbestos if installed prior to the late 1970s.

Just remember to research your particular situation thoroughly before beginning the project. After deciding on the correct ratio of sealant to water for your black mastic floor, spraying it on is a simple task. Holding the sprayer approximately a foot and a half from the surface, spray the sealant in wide, sweeping motions until an even coating is achieved. Once you have prepared the black mastic floor and you are properly suited up, it is time to start the encapsulating process. Chemical strippers should never be used as they can upset the integrity of the black mastic.

Asbestos would be inside the cord and not in its outer covering. Its removal should not entail any danger to you or other occupants of your home. And I speak from 40+ years of experience in the construction trades. If the house is over 30 years old , you’ve got asbestos in other places. Honestly, I’d leave it alone unless you are getting rid of the light for another reason.

William, I have installed many Gymnasiums that had moisture in the slabs ; as all concrete has moisture. we always used either 15 # felt or the 6 mil plastic membrane. yes it will draw some moisture but the felt will still breath some. The plastic stops the vapor completely and I never saw a problem. There will always be moisture coming through the concrete and I don’t have a vapor barrier below the concrete flooring, so my goal is to not have any organic matter directly touching it.

There were two bedrooms in their basement and I lived in one of them. One day after a heavy storm the second bedroom flooded. The carpet was ruined and the floor tiles underneath were ruined as well.

I would fill any voids where there are missing tiles. If you want to paint the tiles that encapsulates it but the underlayment foam for the floating floor will be enough to do the same. If you do not use a underlayment foam the flooring will wear through paint and even some less expensive epoxy paints so a quality underlayment helps in the long run to decouple cold, moisture from the slab.
