Artificial grass

I’ve done all the flooring in a massive house (8 beds, 3 living rooms, 2 kitchens, 3 stairs) at the top of the house is a games/pool room and the customer wants artificial grass, what adhesive would you recommend for wood floors? I’ve only ever fitted grass outside or around a swimming pool on concrete.

 

I’m sure after 3 years he’s done it, also try actually writing instead of just using AI…
