Works well; saves sealant
Would RecommendI had a problem with my zoysia grass and weeds growing up in the cracks that were deep. I used sealant with backer rod to seal them off. It fixed the problem. I also scattered sand on repair when sealant was wet, it looks like the concrete. Backer rod keeps the self leveling sealant from runnig out the bottom of crack and reduces the amont of sealant needed. It solved the problem.
