I have just finnished sanding with the triton orbital grinder attach sander around the edges of skirting. They look good and I would like to know best way of cutting in Polyurethane.

If I rub some water over the bare sanded areas with my finger they blend in.

I know that the floor sanding man used 2 part mix Watyl estapol 7008 part A and B.

I thought if I use this but not sure wether to brush it around edges or wipe to blend in.

Any ideas ??????????
