The product remains stable in storage temperatures of 45°F up to as much as 90°F and has a shelf life of 24 months.

Hole Preparation

It is essential to keep the area around the hole as well as the hole itself free of dust and other debris.

Start the installation process drilling a hole to a specified diameter and depth.

Next, use oil free compressed air for a minimum of 4 seconds to ensure that it is free of debris. It is important for the compressed air nozzle to reach as far as the bottom of the hole to assure a thorough cleaning.

Use a nylon brush to continue the cleaning process. Make certain that the brush reaches the bottom of the hole and that you perform at least four cycles of the brush to ensure proper cleaning. When inserting the brush into the hole you should experience resistance. If there is no resistance, then the brush is worn and you must use a new brush to continue cleaning. Use the brush for at least 4 seconds and apply a minimum of 80 psi for 4 seconds.

Flush the hole twice with water until the mixture of water and dust is cleaned out.


Prior to opening the package that contains the anchor system, check the expiration date on the product label to assure that the product has not expired.

Open the package and remove the cartridge.

Attach the proper Simpson Strong Tie nozzle and extension. Do not modify the nozzle.

Insert the cartridges into the dispersing tool. Dispense adhesive to the side to assure that it has been properly mixed and that the color is uniform.

For dry and damp holes, use the dispenser and cartridge to fill the hole ½ to 2/3 full. Start from the bottom of the hole to prevent air pockets. Withdraw the nozzle as the hole is being filled.

Insert the oil free anchor and turn it slowly until it contacts the bottom of the hole.

Do not disturb the anchor until the adhesive is fully cured.

For water filled holes, insert the disperser with the cartridge and completely fill the hole starting from the bottom to prevent water pockets from forming. Withdraw the nozzle as the hole fills.

Insert clean, oil-free anchor and turn it slowly until it contacts the bottom of the hole.

Do not disturb the anchor until the adhesive has fully cured. carries the Simpson Set 3G Epoxy Anchoring system.
