After 18 years the Sikaflex caulking decided to melt into tar!
And so begins the largest ever repair project on the boat
Removed the old caulking with a oscillating multi tool, equipped with
a Fein hooked cutter
blade. I used a 3 and a 4 mm cutter.
I cleaned up the last rests of caulking and
dirt using a caulk removal tool from
Teakdecking Systems.
Fresh wood was exposed ion the sides of the seams with a multi tool sanding plate.
As I have now lost my faith in Sikaflex and especially after another
boat in my club had to redo his whole deck again because the Sikaflex
did not go off, I decide to go for a polyurethane based caulk
Teakdecking
Systems SIS440 that does not require a primer.
Before putting on the new caulking the grooves where cleaned with
acetone on a microfiber cloth. This removed the last rest of gummy Sikaflex
and removed also any wood fibers left in the there.
Masking off along the seams together with the next step saved me from sanding the
whole deck.
Finishing off with removing the excess caulk with a multi tool knife.
Sanding with 80 grit paper only in the odd places.
