1. It is recommended to excavate the sub-grade approximately 10 - 15 cm (4” - 6”) below the finished surface grade.
2. Ensure there is a proper slope to allow for drainage and water runoff. Do not slope a surface towards structures like buildings, sheds or pools.
3. Sub-surface should consist of at least 5 - 10 cm (2” - 4”) of compacted 1 - 2 cm (3/8” - 3/4”) minus structural base rock or articulate crushed stone.
4. Use a vibratory plate compactor to compact the sub-surface with at least 3 passes for
adequate compaction.
5. In restricted or hard to reach areas where a compactor is not permitted, use of a hand tamper will suffice.


1. Suitable materials are dry 0.47 - 1.27 cm (3/16” - 1/2”) minus crushed stone, decomposed granite, crushed limestone and crushed granite.
2. Ensure the aggregates are clean and free of any dirt, clay, or any other foreign matter.
3. Aggregates with extremely high fines content will achieve sub-standard final results.


 IMPORTANT: “DO NOT COMPACT before OPTIPATH has been applied to the surface” 
1. Install up to 5 cm (2”) of qualified final surface material and grade consistently into place using a rake or screed.
2. Ensure there is a proper slope for proper drainage and water runoff.
3. The aggregates should be graded approximately 1.3 - 1.9 cm (1/2” - 3/4") above the desired height of the final surface.
4. The use of an edge restraint will greatly increase the life and stability of the final surface. If the project will not utilize an edge restraint, it is essential that the edges are adequately compacted.
5. Apply OPTIPATH to the graded final surface at a rate of 15 - 25 sq. ft. per gallon. Apply with a watering can or pump sprayer.
6. Allow 30 to 60 minutes for OPTIPATH to absorb and penetrate into the aggregates.
(On hotter and dryer days it takes less than 30 min, regularly from 30 to 60 min is sufficient, but if there is high humidity, it can take over 90 min)
Do not allow OPTIPATH to completely dry before the final compaction.
 Do not allow OPTIPATH to pool or puddle. 
7. If the final surface looks smeared, mottled or adheres to the compactor, wait an additional 15 minutes before attempting to compact.
8. Compact the surface with a vibratory plate compactor. A minimum of 3 passes are recommended.
9. Surface is ready to use when it is hard to touch. Allow OPTIPATH to dry completely for 24-74 hours (depending on the weather conditions).

NOTE: In restricted or hard to reach areas where a compactor is not permitted, use of a hand tamper will suffice.


For the Optimal Performance:
