Отзыв о 5/8-11 Лезвие для нарезки трещин в беседке для затвердевшего бетона, ремонта асфальта или расширения швов (ширина 0,5 дюйма) от Daniel Shivashankar

Back pool deck had numerous cracks. Watched Youtube videos to find out how to repair concrete cracks prior to painting. I purchased an angle grinder, goggles and paper dust cover, as I knew there would be a lot of dust. The grinding wheel is tapered and easily followed even small hairline cracks. I wanted to open the cracks wide enough to provide room for quick set concrete fill. This grinder wheel needed no pressure to open the cracks to a tapered width of about 1/4" and a depth of about 3/8". You need eye and breathing protection as grinding creates a lot of dust. I could see no wear to the grinding wheel after tracing over 100' of concrete cracks. Just be careful with the angle grinder.
