WR-LPU can be recoated without sanding within 24 hours.  After 24 hours, sand with 220-320 grit paper.  

When rolling and tipping, best results are achieved by applying no more than 2 coats per day.  Allow minimally, 4-6 hours of dry time before recoating.  This timeframe allows the WR-LPU to develop water and chemical resistance.  When the next coat is applied, much better flow and level occur. You will also see an improvement in wet edge extension (more open time).

Recoating in the 1-3 hour window is not advised because WR-LPU has not developed sufficient water and chemical resistance.  Poor application characteristics such as reduced flow and level as well as decreased open time will result.
