QUAL A LIXADEIRA E LIXA CERTA PRA LIXAR MASSA ACRÍLICA

The sander for acrylic putty is definitely a rotary orbital sander! Rotary orbital sanders are all sanders that vibrate and rotate. This is good because when they vibrate, they scratch the putty, but when they rotate, they remove the scratch and leave a good finish. The rotary sander is also an excellent option! Unfortunately, orbital sanders - which are those that only rotate, including the giraffe sander - are not good options, this is because they vitrify the putty, as if they were polishing it, and they do not sand well. You need to use much thicker sandpaper and apply a lot of force! So, to avoid headaches, go for a rotary orbital sander with 80-grit sandpaper and it will work!
