The reference ratio of 3-4mm high elastic particles mixed with high-strength single component glue is 1:6.5, mix evenly and pour into the paver. The laying thickness is 10 mm. Curing and maintenance for 24 hours.
3. Then mix the air permeable surface material with 1-2 mmepdn particles of the same size into the spray gun of the spraying machine and tilt it to 60 ° for spraying in the same direction. After the spraying is completed and maintained for 24 hours, spray again in the opposite direction.
4. After 48 hours of curing and maintenance, the site can be marked.
5. The site can be put into use after 15 days of maintenance.
