Hi,
I purchased a brand new townhouse without flooring in 2014. I had defective tiling installed on my ground floor and staircase. Just had the tiling removed and noticed a tar black glue on the staircase. The tiler will not tell me what glue they used there. The tile stripper told me this black glue is called Blackjack. After searching online Blackjack glue may contain asbestos. I am concern about my family at risk with asbestos now? I am getting pieces of the black glue for testing. Does anyone use this kind of glue on the staircase?
