Measuring the Gelcoat Angle

How to Measure the Angle of the Gelcoat

This is most easily done with a digital protractor (angle finder) that is available at either Home Depot, Lowes, or any other big box hardware / home improvement store for about $30.  This is a great tool to have in your toolbox!  If you'd rather not purchase one, just let us know - we'll send you a loaner to use.

Step 1 - Zero the Meter

This is by far the most important step when measuring.  Set the meter on the deck, in the same direction that you're going to be measuring the angle, then press the ZERO key on the meter.  After you're done, the meter should read 0.00.

Step 2 - Move the Meter to Measure the Angle

Now simply move the meter up to the surface you want to measure, without rotating the meter.  The left or right side of the meter will be against the gelcoat to get the angle with respect to vertical.  That's it!  Take a picture of this measurement and set it to
