First time posting. Little bit of history. Im located in west Michigan. Purchased an existing company last fall. Worked Aug-Nov last season. PROBLEM IS: I have been driving around looking at jobs we sprayed last fall. Some look great and some look .....well...bad. We use Star-seal. 30% water. 2 lbs. silica sand. Sprayed. On all jobs. There are jobs that were done the very same day out of the very same tank with very different results. How can this happen??? Some material is wearing well and some has worn off. Any comments are welcome. I want to produce quality work that I can be proud of. There is such inconsistancy. I dont know what the problem is.
