How can I remove ugly carpet glued to my kitchen foor with mastik? ?

Hi Carol, this is one decor idea that I never understood. What a mess when food spills. Try in a corner and pull. Ventilation, wearing protective clothing and a good respirator, you can use a heavy duty remover to get up the mastic. The big box stores do sell them. It may be a special order product. Or go to a marine shop to purchase. The tile probably is bad underneath so that too will need to be removed or covered. If it's linoleum, I'd suggest covering with ceramic tile. Good luck.

I’d start by borrowing a long-handled ice scraper to save my knees and back. Try to remove as much of the carpet as you can.

Perhaps use a a good box cutter to cut the carpet as best you can into strips.

But read this first, and wear gloves, a mask and safety glasses because old carpets are routinely disgusting no matter how clean your house is.

You'll have to use a good stripper just remember to ventilate and do small sections at a time so it can easily worked with and reached

What is the floor underneath? wood, tile, linoleum, concrete?

Linoleum..... now this was genius, never seen that done with a sawzaw before but will sure remember this next time I encounter it.... https://www.youtube.com/watch?v=_8P4nGJlIGs

Then if you've got the black mastic below the linoleum, I would rent one of these....if your going to try and refinish wood floors before.... https://www.youtube.com/watch?v=QI-8v5d3mqY&t=238s

Wear goggles, gloves, mask and long sleeved shirt and old pants.
