Primer

[BigBryon]

What kind of primers are we using today on are boats before we paint on our color.

PPG K36 Builds up easy if you want to lay it on thick and also sand off just as easily. Works great with the PPG Concept that I shoot.

The K36 is great much superior and better to work with than the original K100. I've actually gone away from Deltron primers to a much simpler rattle can primer made by SEM called High build primer. It is however very expensive, about $11.50 a can but is worth the money!

The PPG DP48 with DP401 catalyst epoxy works great. I would have to double check the actual numbers.

Current numbers are basically the same- DP48LF & DP401LF are for the epoxy primer. Like I've said before, I shoot the PPG DZ3 hi build primer then sand virually all off to fill imperfections. Then shoot the DP epoxy primer & paint. One of the things I really like about the DP primer is you can get it in white, makes a nice neutral base color. B)

Thanks Guys for all of the information, but there must be more kinds of primer that we can use.

Well do want just any old primer, or what works??? Don't cut corners here, the primer is the heart of any good paint job, it gives the paint something to adhere to.......

We need to know what primer works the best, not that cheep old primer.

Hey Bryon

I just got done painting my sport 21 and I used DuPont 421-17 2k Urethane primer. It is a great filler primer. KEN :unsure:

I don't think your gonna get better than what Don suggested. I also think they are water based sealers that protect the boat through the long run.

One thing you have to consider with primers is if you will be taping your radio box lid to the paint. I have had the primer layer itself separate while peeling tape off. There was primer on the bottom of the paint chip and on the boat surface.

This ain't cheap. And if if ain't the best then it is probably as good.

I thought that's the reason for using primer? Other than for a smooth fill, the only reason to prime is to prevent separation, no?

Yup. B)

Hi Guys

Separation is nearly always caused by paint incompatability. Primers purpose is to fill surface imperfections and provide a surface for the chemical bonding of the paint. It also provides a consistent base colour with which to work on eliminating shade variations in your top coat.

I found that everything i paint now gets a primer coat, it fills imperfections, gives the paint something to stick too. And as a beginner painter, i found it makes the painting go smoother and less things go wrong.

"Separation is nearly always caused by paint incompatability........."

Yup, & the other is usually a surface that's not properly cleaned before the paint goes on. The best primer in the world would hold it's surface or it's top coat if there is a residue of oil from a few fingerprints. You may think your hands are clean but this is why I always stress wearing those sugical gloves & cleaning with PPG DX330 before the primer & before any paints & clears. It's possible that where Preston had his primer lift he might have missed a spot cleaning before the primer went on, even as thorough as he is. I've done it too, that's why I now clean them twice before shooting.......... :huh:
