SQ FT COVERAGE ON NON FLAT SURFACE

SQ FT COVERAGE ON NON FLAT SURFACE

SQ FT COVERAGE ON NON FLAT SURFACE

(OP)
I'm needing to determine the square foot coverage on our product, wich are LOuvers. I can't just determine by square foot because each louver has a depth.
Any suggestions will be appreciated.

RE: SQ FT COVERAGE ON NON FLAT SURFACE

What kind of accuracy are you wanting and what type of louver are they? Are the louvers a formed louver of just a piece of material set at an angle? What do you need the square foot measurement for?

RE: SQ FT COVERAGE ON NON FLAT SURFACE

(OP)
There are different types of louvers (rainscreen,drainables,non drainables,formed metal louvers, air conditioning, thinline & door louvers) as I mentioned before there are different types of louvers each with different depths. I need the square foot measurement to lower down our paint inventory levels by determining how much sq ft does a gallon of paint cover.

Thanking you in advanced for your response...

Miguel.

RE: SQ FT COVERAGE ON NON FLAT SURFACE

Do you use any CAD software to design the louvers? Most CAd packages can determine area.

Up to now we've been getting the perimeter on each component then we multiply it by the lenght and that's how we get our sq ft. The issue is I that I can't determine how much paint would we need to paint the product, and this is becuase it's not a flat surface we're painting.

RE: SQ FT COVERAGE ON NON FLAT SURFACE

You didn't answer my question. Do you have these parts designed in a CAD system?

Yes, we have each separate component in AUTO CAD.

RE: SQ FT COVERAGE ON NON FLAT SURFACE

Then the answer is right in front of you...ask the CAD guys to give you a surface area measurement and you're done.

Well it isn't quite that simple, because like I mentioned before each louver has a depth, in another words it's not a flat surface we're painting. Therefore it's hard to determine how much square footage does one gallon of paint cover. We paint the louver assembled.

RE: SQ FT COVERAGE ON NON FLAT SURFACE

Surface area is surface area, whether it's facing up, down, left, right, whatever... unless you're forced to make adjustments to paint use based upon tha angle of spray and potentially uneven coverage, that's the best answer you're going to get.

get 1 gal paint.
paint ten parts.
measure paint remaining.
(starting qty- ending qty)=qty consumed.
qty consumed/ (num parts painted) = qty paint per part.

Forget area your making this too hard.

Composites and Airplanes - what was I thinking?

There are gremlins in the autoclave!

You've also got to deal with the overspray issue the paint accumulation issue and the effective thickness issues. Unless you have some means of assuring the same thickness on all surfaces your calculated paint usage can be off dramatically. I would do some empirical testing and monitor the paint usage. I believe that will get you a more accurate picture of the usage. After you have gathered the empirical data find out if it relates to the calculated data. I would also monitor the applied paint thickness across the louver.

Thanks to all of your replies.
