Hi Stephen, your probably applying too much, try and sponge just a little on, basically overload a sponge and squeeze it just about dry then wipe on in one continuous motion, you should barely be able to see the film, any problems give us a call , best rgds
Hi, please help me, I am a beginner and do not know how to use WAX and PVA. I have tested them but I do not have a good result. I need to know how to use WAX and after how long to use PVA and how many times to apply.
I want to wrap over abs pods carbon fibre skinning says to add pva first is that just help pull off. Or can I spray glue the part or mix resin first then lay my weave on I want the weave to stay in place
I'm making a molding for my motorcycle rear fender, at this point I put a plastic bag over n brown tape over bag for easy release, what u suggest? can I use the fender with out the plastic and tape n just add the pva to bare metal of fender? N add the pva over the fender???
quick question I made a molding last night added the fiberglass with the hardener but this morning is still sticky I guess it didn't dry cause maybe not enough hardener how can I fix this error ?

Nice Job, But, what was that surface you put the PVA on ? Was it waxed.. Everything beads up on wax.. Do I need mold release ? I'm trying to make my first fiberglass mold. I'm making Hub Caps for my truck.. I CNC made my own design out of expanded stryrofoam.. I like it, I coated it with lots of Poly Urethane, sanded it, and put 4 coats of car wax on it, It's slick and smooth, I'm ready, but nothing sticks to wax.. What now ? LOL !
Hello, the PVA in the video was applied to unwaxed melamine as this is fairly self releasing. We tend to use it a lot for various jobs. You shouldn't see any beading on the waxed surface, as it should be a fine coat with even dispersion. If you see fish eyeing, you've got a little too much wax in that area and will have to touch up the PVA for an even coat
PVA mold release is "Poly Vinyl Alcohol", PVA glue is "Poly Vinyl Acetate" .. It can be confusing. Don't listen to any You tubers that tell you they use watered down glue.. It's BS.. I've already made that mistake..
if you add it to a surface which is a bit rough (Marine plywood) will the fiberglass still release? if you where using wax as well do you add the pva after right? Thanks E
@@snorttroll4379 basically get it to the finish you require. there are many products you can use. the method we use is that we seal the ply with a good sand and seal varnish such as shellac. then sand its down, then apply several coats of Durabuild surface primer. once cured use wet and dry sanding down to maybe 1200 or 1500 grit then polish with a polishing compound such as farecla select if a shiny surface is required.
Thanks for the video!! I don't have a spray gun (since I'm just an avid DIYer) so this method is absolutely perfect and cheap for me, cheers!
If the pva is a bit thick on application,just add a bit of water to the mix to "thin" it down ,job done

how to dilute pva? because my pva is a little thick
Just one point. Always paint away from edges. Never towards.
Our mold having GI sheet....how many layers of PVA need to apply for easily removed
The information is in the video

Hi, the PVA is to stop the part from sticking to the mould so use that first

Can this be used on particle board? And if any preparation is needed such as a base primer what product would you recommend?
You would need a base primer to prep the particle board surface to mould from, but then yes, you could use the PVA release agent

ChiCitySoul . What ratio did u use in mixing?
for 1 kg of resin use 6ml hardener. will dry very nicely within 5-8 hrs will be non sticky .
you have not added enough hardener. Wait for more time at higher temperature

I've just used Johnson wax in the yellow can from Home Depot; 4 coats, and the PVA went on with zero beading-up.
I try calling that number gives me error
is this a specific PVA or can you use PVA glue?
Hi Natasha, the PVA release agent is completely different
PVA mold release is "Poly Vinyl Alcohol", PVA glue is "Poly Vinyl Acetate" .. It can be confusing. Don't listen to any You tubers that tell you they use watered down glue.. It's BS.. I've already made that mistake..
if you add it to a surface which is a bit rough (Marine plywood) will the fiberglass still release? if you where using wax as well do you add the pva after right? Thanks E
It's best to get the surface as smooth as possible, sand it down and use a base primer to fair it off
@@ecfibreglassuk Thank you for the reply!
@@ecfibreglassuk fair it off? what does that mean?

Hi do you still have to add the wax before or does the pva do the same?
Hi,
You can add the wax also, but it's optional
Awesome video thanks
Can this pva be used on foam??
As long as it's not reactive with poly vinyl alcohol, it should be fine
how long till dry?
Hi about 30 minutes..
why my pva keep running away?
Shake it well before using it
Come on, man!.... kill the damn music! 👎
