Pva application fish eyeing

Group: Forum Members Posts: 34, Visits: 94	I have a big plug I'm ready to mould. After so many failures with easy lease I was going to use pva. The plug is sealed with s120 and has a clean smooth finish. When I apply pva though it fisheyes like its a wax resist crayon picture and I get bad patchy coverage. Is there something anyone can recommend to prepare the surface for pva application? I always pre clean with EC mould cleaner so it should be contaminant free...thanks Edited 5 Years Ago by moonpie

Well I bit the bullet and moulded without PVA. The plug had taken many months to model so was a bit nervous about getting either the mould or the plug out in one piece but decided to use wax on the.....

Hey man, when I touched my mould up with gelcoat without wax additive, I left it in the sun and cured nicely and quickly. I used an eletric detail sander

Or just flash tape over it (i normally use way more than 2% catalysts for touch ups)..... works great:)

Thanks guys, the recent hot weather has allowed me to make the gelcoat touch up outside quite nicely so im on with the sanding now. Once done I need to make two mould flanges as this piece will be...
