Hi, as the title says I'm having to re-do all the mastic/silicon round the upvc windows and on the joints of the upvc sills and upv internal finishes.
I've taken off the old mastic off with a chisel and stanley blade without damage (what a boring job that was) and need to mastic new stuff in all shiny and bright.
I have the tools: mastic gun, filler with antibacterial, and all my fingers ready to use to smooth the stuff, as well as the tee shirt I'll wear, that I hate most, to wipe said fingers on and annoy my other half.
So quick questions about preparing the surface:
As I say I've cleaned down all joints but in places can still feel a thin film of mastic....what is best to remove this and get good adhesion from the new stuff.
I have silicon eater from Toolstation, but don't know if that would leave a residue that I need to clean afterwards....
and I have Acetone, but would like to be advised if that would damage the upvc, or need cleaned up after use.
I also have UPVC cleaner from a previous diy job, but only used this to take off grime.
Lastly I have a box of Wonder Wipes donated to me the orther day, ..never used them before.
Any advice as always is appreciated, thanks in advance.
