Sikaflex finish

[Gerry in Oz]

Hi all,

I am very pleased with the bond strength of Sikaflex 295UV however the surface finish I have achieved is bordering on the embarrassing. Can anybody suggest a way of improving the surface finish of a dreadful looking Sikaflex surface finish.

Many thanks,

Gerry.

Cover it up

The lesson I learned is the finish look comes with smoothing the sikaflex out as you apply it. And don't do the whole canopy then smooth it out - do 6 inches at a time because it skins very fast.

But now that its dry I use simple half circle seal from FlyBoyAssessories who I believe advertises on this website - Flightseal "D" Profile Weatherstripping.

Or don't hide it at all - be proud of no fasteners!!!

Rehabing the Sikaflex

Sikaflex sticks to itself pretty well. You could carefully cut down the high points with a very sharp razor. Then take some additional Sika, smooth it on and shape with an old credit card or something similar. Try a small patch first or make yourself a test piece to experiment.

You can sand it after its cured to smooth it out, then maybe add another layer and smooth it with you wet finger.

+1 here, it wet-sands very to a very nice matte finish with 320-500 grit. Kind of pills off as you go but looks very nice.
