Opinion on just painting rough surfaces?

How is 6 gallons of fairing compound 15 lbs when epoxy weighs 9lbs per gallon?

I’m nervous here. You’re way underestimating the weight of things you’re adding.

That’s actually 135lbs, not 15. And even if you sand off 50% of it, you’re at 67lbs, not 15.

Usually for fairing you're adding a very lightweight filler. So the mix should be lighter than the original epoxy.

I looked up premade polyester faring compound. A little lighter at 6 pounds.

Still 90lbs

Not much lighter actually. Because microballoons don’t bulk it up as much as you are thinking. You can see that in the above numbers in my last couple posts.

And every pound of that filler is in addition to the paint. I have to put gallons of paint on. There will be a certain number of gallons of that. Matt has to put the paint on too. But if I put all that weight of the filler underneath the paint, I’m really looking at some added weight at that point.

We used a “special” exterior water based house paint with a mildew inhibitor on the interior of our boat. We painted about a year ago and no signs of mildew yet.

Yeah that stuff really works. Along with rustoleum and any other mold inhibiting paint.

I’m very impressed with hardware store paint and products. Times seem to have changed when it comes to that type of thing. The non-skid is incredible too.

I used some GE silicone caulking for sealing up the panels of my shower area, which just went straight over the rough fiberglass. Came out really nice and has a very long guarantee against mold. I forget if it was 10 years or 20 years. But not even a spot on the caulking. And I did it a couple years ago. It was something I had just completed before the heart attack side tracked me.

Strange math... 6x6 = 36 lbs. But I've measured the stuff we use and it is 5.6 lbs a gallon. Now divide that in half.

Even if you could clean, prep and paint a rough/textured surface, just think about what you’ll do the first time you have to clean it. Rags, sponges, paper towels will all shred on the rough surface. Just imagine trying to clean mildew off of a textured ceiling.

Ooof.

That’s 97 degrees in the salon and no wind math.

I am down a generator right now in south Florida sitting in a greenhouse.

I thought you used 15 gallons for a minute.

I was also working on making a mobile app right now and had to quit because I can’t think straight.

Have I mentioned how much I hate this heat? Lol I cannot wait to get out of here. The heat is just awful. Makes you stupid.

Sitting here cooking alive waiting for my generator part.

Did you see the pictures in the first post? It’s a different kind of rough. You’re not picturing the right thing. It’s smooth to touch, it’s just bumpy and lumpy.

Before I moved in I sponged down exactly half the boat interior to get dust out. One sponge did the whole thing.

Never been a problem for us, but I guess it depends on the amount of texture?

It might be time to throw a switch and try to steer this thread back in the right direction. It seems to be going off the rails like they usually do.

I’m asking about resale value. I don’t really care about any other stuff, even though I’m responding.

That’s the opinion I’m looking for.

Have you really opened this thread to find out the resale value?

Struggling overheating right now, but I believe that’s what it said. Yes.

Because otherwise, what would the topic even be?

Trying to ask what people think of the rough surface designed in with very nice cabinetry, floors and ceilings. Having everything top notch and expensive looking, but simply painting the walls without smoothing them (they are already fair of course).



I have said this a couple times I think.

There was quite a bit of discussion on it in the first pages.

Now it’s off the rails.

As far as quantity of fairing compound, it wouldn't take a whole lot to just fill in the texture. You're not trying to fair it to a smooth, even mirror finish. Being a hair wavy or something is fine, you just want to fill to the high spots of the fiberglass weave (and nothing more). Applying and lightly sanding a high build primer might be enough to do it (basically sand until you're starting see the high spots of the weave through it, letting it fill the lows.
