Calculator Old Fashioned:

A must-have tool in any hectic day, the calculator will take some of the most complicated math to make it simple.


Naturally, this process was time consuming and labor intensive. The accuracy of slide rule calculations is subject to human error, too, because if you accidentally read the tiny marks on the scale incorrectly or place the cursor in the wrong place the results will be flawed. Now, while you can argue that a calculator is also prone to this type of human error, but, the odds of incorrectly pressing a key on your calculator’s keypad is obviously less than the chance of someone making an error in this process; Oftentimes a group of five or six students working together as a team might need an entire class session to solve a problem. It’s best to consider any epoxy coverage calculator a good starting point, but there are other factors and variables that might impact how much epoxy you will need. Porous surfaces that require a seal coat will increase the amount of resin needed. How are you handling the edges of the surface? You will need more if you are allowing epoxy to run over the edges, compared to building a dam or wall. And, you’ll probably lose a little to mixing or overflow. For most epoxy applications, 5-10% extra should be added to account for the inevitable wasted epoxy that stays on the stir stick, or stays in the bottom corners of the mixing cup, or accidental drips.
