Rollermarks on floor using 2 part waterbased epoxy

[LaFlamaBlanca]

What are some of the reasons you would see some roller marks on a concrete floor that was painted with a 2 part waterbased epoxy? This was after the 2nd coat and it was also backrolled.

Are any of these possible causes:

1. Not taping off the floor and painting in separate sections at a time.
2. Started backrolling too soon/late.
3. Product wasnt mixed well enough.

In general the most common mistakes that we see when it comes to back rolling are:
*Backroller roller cover becomes saturated with material.
*Backroller should roll in a direction perpendicular to the load roller (this applies, in particular, to clear coat applications)
*Backroller applies too much downward pressure when rolling
*Excessive backrolling and/or backrolling over hot material (material is starting to setup, cure) which is unlikely given you're using waterbased product.

Rolling using the wrong technique can also cause problems. Just going back and forth can create lines. We normally recommend when rolling to use an "M" and "W" pattern.
