How to dress premtool polishing pads

[acaciaguy]

Thank you. How are they on honed and filled trav? I was thinking of getting a half bullnose wheel also. Any thoughts?

Not sure, I’ve not used them on Travertine. I expect they’re pretty good. I’ve mainly used the 50, 100 and 200 to achieve good cut edges on porcelain and to get close mitres on ceramic.

When dressing is applied to polishing pads it generally means nothing more than running the pads on something first to wear off the manufactured coating and expose some diamond.

An offcut of granite is ideal for this.

Travertine tends to be a little soft for dry diamond pads to be fully effective. We generally recommend Silicon carbide discs for sedimentary and metamorphic stone. That said they may work, but you might find you have to periodically dress them on something more abrasive to expose more diamond to get them to polish. It depends on the compound used to manufacture the pad itself.

Thank you for this.

For me, soft stones are easier worked with something like Sait Pads as Alan suggests.
As far as bull nose grinder attachment is concerned, you’re better off learning how to do it by hand first, it will give you a much deeper understanding of what you’re actually doing.
And tbh, they’re not the easiest things to use anyway.

I've had and used bullnose wheels from ATS for years, great bit of kit. Easy to use and with a bit of final working and polishing with SAIT Plain Silicon Carbide Discs they give a great look and finish.
not only do they work great on stone i also use them to good effect on full bodied porcelain.

get one and practice with it for a bullnose or even for making stone or porcelain windows boards

Noted. thank you for that. I will. With honed and filled travertine is it best to bullnose on the factory finished edge or can you work on a cut edge. Once worked on with pads to get bullnosed edge to you need to re-fill with resin and polish or will just polishing and sealing with rest of tile work

Cut edge or factory edge makes no difference once you start going down this road.

You can work with the Sait pads upto a highly polished finish. Filling with resin is a possibility if you end up with holes that will depend on the quality of the stone
