Lath and plaster asbestos

It is not likely, but all including lathe and plaster have been found with asbestos.

For your own peace of mind or lack thereofyou might take a piece of the plaster to a hazardous materials lab and have it analyzed for asbestos.

If there is none, you're probably okay. Your hacking and coughing is the lungs' way of clearing out the "gunk". It should subside within a week.

The conclusion was that the second layer in from the outside has trace amounts of asbestos. They are sending the full report through to me later today. I attached a photo. The side with my thumb is the inside. The thick gypsum part had no asbestos, and the outer I presume skim coat has no asbestos. But popcorny looking part is where the trace amount was found.

Should I still use extreme care? The stuff does make a pretty dusty mess, so that is my concern. I live in a neighborhood of 40's houses, and I'm pretty sure everyone around here knocks entire walls down with the stuff falling on their faces, so I may be overthinking this!

Although we did lose a family friend a while back to mesothelioma, so that probably is what is causing my anxiety. Sean, to me that photo - shown above - looks like a layer of drywall bonded over a layer of plaster skim coat over a layer of plaster base coat or of cementious plasterboard.

Unfortunately with no more information than the age of the rock lath or gypsum board that you're removing, if you have to make a Dusty demolition mess then you need to either treat the material as presumed to contain asbestos, or to have representative samples tested.

With a solid selection of games and a very large selection of markets, it is one of the better sites to use for your esports betting needs if you like to cover multiple games. Bet365 does have a slightly unfriendly website design that appears to heavily use Flash, meaning that there are simpler options available. All of the top esports titles are supported, mostly with many matches and more markets than most competitors.

In-play betting is also supported, but only with limited matches and markets, and many in-play games have a lot of downtime on markets thanks to betting suspension. The site does, however, feature some solid welcome offers for new customers and it has a large amount of deposit and withdrawal options.

Much like many other competitors, the esports section of Bet365 is a part of the traditional sports betting section. While not a major focus, it receives better treatment than many sites and can easily be found.

In order to place a bet, you must be logged into your Bet365 account. From the main sports betting page you must select esports from the menu on the side, which will bring up the main esports page. This will then display all the competitions that are available and the markets that are available for that competition. Irritatingly, individual matches are not shown on this page so you need to know what competition the match is a part of in order to find it.

Once you have selected the competition and the market from this page, you will be shown a page with all the available matches, and the teams that can be selected for your chosen market along with the odds. Clicking on the team you wish to bet on will add the bet to your bet slip, which is constantly available on the right hand side of the screen. On the bet slip you can enter your stake, which will automatically display the potential return.

Then when you are happy, you can click the place bet button to confirm and place your bet. Placing a bet on this system is not as easy as it could be as there are a lot of steps to go through, and locating the specific match you are looking for requires some prior knowledge of the competition it will be in, or you will be searching for awhile.

Once you get the hang of the system it becomes much easier, but it takes a bit to get used to. We also had some issues with the Flash requirement, and were redirected to the mobile version of the site multiple times, which did not make the process simple at all.

There is a good range of games available, with all the major titles such as League of Legends, Counter-Strike: Global Offensive, Dota 2, StarCraft 2 and Call of Duty all available most of the time. Other games may be available if a major event is taking place. All of the major tournaments, and even some smaller ones are available, with the likes of The Canada Cup in Dota 2 making surprise appearances.

League of Legends features many game-specific markets such as who will slay the first Baron or dragon, or how many will be killed in total as well as more traditional markets such as the match winner, the tournament winner, individual map winners, and correct map scores.

Other top games such as Dota 2 feature similar bets, while the likes of Call of Duty and StarCraft 2 tend to stick to more traditional winners and map winners bets. Not all matches are available, but many of the top tournaments feature in-play betting across most of the games offered.
