How do I avoid roller lines and marks?

Be sure to use the proper UDT-supplied, high-quality roller covers recommended for the application method being used.
- The T-bar/back-roll method requires a ¼” nap mohair back-roller or 5/16” micro-plush roller.
- The rolling method requires a 3/8" nap woven roller.
- Tile & grout (T&G) rolling method requires a 3/8” nap woven roller, and (if back-rolling) a ¼” nap mohair or 3/16” micro-plush roller.

When back-rolling or rolling, feather it out (the “airplane take-off” method of lifting the roller up at the end of the roll away from you).
Follow seams or lines in the flooring to help hide any potential roller marks.
Move quickly and do not roll into any areas that were applied more than 3 minutes earlier.
Do not apply a lot of pressure on the roller when feathering. Use just enough pressure to help knock the material down and remove any roller lines.

If you are using an additive like UDT Aggregate #240, you may need to roll aggressively to help spread the additive if it has pooled from sitting too long.
