When to Paint?

But rolling it comes in second place and is still quite effective, right?

It's not too thick for a sprayer?

with the right sprayer you can spray waterproofing tar on concrete foundations, or drywall filler on interior walls

sure, but the smoother it is the less dirt and grime it will hold, therefore lasting longer - if I were to go that route I would lay the material on thick with a heavy nap roller sleeve, then smooth it out with a short nap roller sleeve - do it in sections moving quickly so you keep a 'wet edge' - lay it on heavy enough so the paint looks like it has little braids on the surface, then smooth that with the short nap - that should give you about a 10 mil thick coating - the rollers should almost or partially be sliding on the surface - what thickness does it specify on the paint can?

Thanx for the rollers tip.

I suspect my Wagner Airless won't be up to this task!

Calls for 125 wet mils, 1/8" thick. Directions say, spray, roll or brush.

When painting the roof in an elastomeric paint, what method delivers the smoothest result?

We used a roller. The paint is thick and not meant to be thinned. There is an acrylic micro bead component that maximizes the thermal protection. Other reviewers that used a sprayer said they had to stop multiple times to clean their spray gun. (Which probably means they didn't have the right gun)

Our roof is 33' and 2 gallons primer and 2 gallons paint gave us 3 coats each by roller. Each coat took approximately 45 minutes to apply. Definitely use a long arm roller.

This stuff is working great so far (made for bus roofs!) and we will update regarding effectiveness as we go.

@o1marc, which paint are you using?

 

[DaCaNoWiSe]

I would listen to Sleddgracer. Sounds like he knows his stuff.

We know our amateur limitations. ��

Question for Sleddgracer:

We have been researching paint for the body of our bus. We saw some people recommend Tractor paint and we've heard Exterior House paint with a hardener.

Any thoughts on either?

Henry's Tan Tropicool
Directions don't call for a primer, is it necessary?

WOW! - that is THICK ! - you will have to really lay that on with a roller - a commercial airless could do it - one that pumps 3000 lbs @ 5 gal per minute with the petcocks wide open would work

Do you taper it off at the tape edge? Thoughts of having body color down first, so masking a thick edge is a PITA when it's time to paint the body.

 

[DaCaNoWiSe]

Don't use house paint.

Do you have a better recommendation? I see you are in Eustis. We will ultimately be living over in Ormond so we are trying to find the best paint to withstand the humidity and sun.

 

[HazMatt-SKO]

Yup,

ANYTHING other than house paint!
Unless you're a masochist who enjoys the pain of painting... [emoji6]

I'd mask off an edge like that if you don't have a natural edge to work to

if you aren't going to use automotive paint, at least go to fast dry machinery enamel and add some hardener - 'Japan Dryer' is the best one - cobalt drier if the other isn't available

I actually do love to paint. I will paint and repaint anything and everything. I tried to paint the kids, but my husband stopped me buzzkill. OK. No house paint.

I will look into all. Automotive paint is a bit pricier so we were just looking for other viable options.

Do you have an opinion on WHEN to paint? Before building the interior (it is down to its shell) but after we build the undercarriage boxes, etc. Or should we save it til the very end?

I've been following this site for years and you post quite often and seem very knowledgeable so can you drop some of that here?
