For safety, I have worn rubber gloves, as was pointed out on the packaging that the adhesive irritating to the skin acts ... I also recommend to work in a well ventilated area, at best, with the windows open because of the glue smells very strong ( then, after drying, not more, do not worry).
Wait quite as long as indicated on the package, you have to before the substance does not merge well =)
In my opinion, the Tube is also a long time keeping (which is very good for the low price), have 3 pillows decorated and not even used half.
All in all, recommended: D fast alternative for small repairs without residues or hardened material.
