Painting the roof

I have a 1983 Excella 31' and I would like to paint the roof white.
1. Should I tape off and cover the sidewalls and front?
2. What type of cleaning product should I use?
3. Should I remove the pharr bond and reapply or leave it off?
4. What type if any base coat should I apply?
5. What type of white paint?
6. What amount of time should I a lot for this project?

Any help or pictures would be helpful. I want to do this job right.
Ginger

For best results tape off everything that you don't want painted. Sand the surface with at least 220 or more coarse paper to insure proper adhesion.

I like Industrial Imron. It will brush or roll on and smooth out nice, super durable, and only about $130 a gallon. (Which is at least twice what the job will require. )

Painting the roof

I sprayed it on my roof about two years ago with no primer.

There are folks who will say that Aluminum must be primed before painting, but I have had good results without primer.

I just sand it really well.

A store that sells DuPont car paint should sell this product.

Industrial Imron 3500 HG.

One good coat is all you will need.

A product called bus-kote, white has ceramic flakes, was developed from tech. for nasa, for school buses. Will not streak or chalk not expensive. Google bus-kote to get specs etc. it can be rolled on, or brushed. I do not rep.them or any other thing. It's what I read about it and testimonials [no bad ones]. #39.50 a gal. less than Imron plus ceramic to insulate not just white to reflect sun. I have used Imron with hardener, plus not flexible.

I used a product called Ceramiflex that is an industrial coating, but I don't think they make it anymore. It was detailed here: http://www.airforums.com/forums/f478...lex-98479.html

They have other similar coatings that you could probably use just as well. This company makes commercial products that can be applied to bare metal without the need for primers. The stuff wasn't cheap, but it works very well.

Imron is an activated product that will stand the test of time period.

It will not streak, and it actually is quite flexible.

Perhaps insulation will make a difference of sorts, but as far as the use on my trailer, when parked in direct sun I can leave my hand on the painted surface without getting burned, not so on the bare aluminum.

I am just throwing it out there what I used and what I think worked well. It took less than a quart to cover my roof, and it works for me. (Buying just a quart costs quite a bit more per ounce than buying a gallon)

It appears Ceramiflex went bankrupt and has closed down.

If you are referring to the product called Ceramiflex, it is no longer being produced. The company, Sealoflex is still alive and kicking, and has a product called reflectowhite which I think is what I would use if I didnt go with the ceramiflex initially. Here is a link to their website: ReflectoWhite | Sealoflex


They sell through distributors so you would need to find one local to your area.

HTH.

I have no affiliation with the company, but am happy with their products. Here is pertinent info on the reflectowhite coating:

From the website:

Description
ReflectoWhite is a waterborne, single component roof coating.
It is a tough, flexible material, which displays good UV and
ozone resistance. ReflectoWhite is used as a protective coating
to existing roofing materials such as single ply, modified asphalt
membrane and metal roofs.
Uses
To provide a highly reflective surface over roof surfaces
of all types
For coating of all types of roof substrates
To provide protection and add life expectancy to existing
roof surfaces

Advantages
Energy Star Rating
Ultraviolet and ozone resistant
Mildew and algae resistant
Expands and contracts with the roof surface
FPL approved
Ten Year Warranty
LEED Compliant
Excellent solar reflectance: 86%
Reduces cooling costs
Fast curing
Excellent low temperature flexibility
Adheres to almost any roof or wall substrate including
stucco, concrete, metal, wood, asphalt, foam, barrel tile,
PVC, TPO, EPDM, etc.

Instructions for Use
Surface Preparation
Surfaces must be free of dust, loosely adhering particles, oil,
grease and previously applied incompatible coatings.
Priming
Unpainted wooden surfaces, Asphalt, Weathered galvanized
steel, Non-ferrous metal and PVC:
No priming is necessary
Application
Apply coating by brush, roller or sprayer. Allow the first coat to
dry then apply the second coat perpendicular to the first.
Coverage
Smooth surfaces:
50 sq. ft./gal. (total for both coats)
Granular and Irregular Surfaces:
40 sq. ft./gal. (total for both coats)

All about the same as the ceramiflex I used almost 3 years ago.

I got a brainstorm and went to the bus conversion forum sites. It appears Bus-kote is their product of choice. Im going to contact the company and see what they suggest for the AS. Will keep you posted.
