## Overview

The Fast 2K Deck Post Anchor Mix is a revolutionary concrete alternative designed for quick and secure installations of deck posts, fence posts, mailboxes, and playground equipment. Weighing only 2.5lbs, this fast-setting, expanding composite footing compound eliminates the need for heavy concrete and messy mixing, providing a waterproof solution that prevents rot and deterioration.

## Description

Instructions  *Mix the Two-component Kit *Pour contents into hole *Let sit for 15 minutes Each two-pound bag easily sets a 4" x 4" post (10cm x 10cm) in an 8" (20cm) x 3' (91cm) deep hole. This means that you can set posts with smaller holes and get more from each bag. EasierSpend less effort loading and unloading large trucks with Fast 2K. A single two-pound bag replaces two 50-pound bags of concrete. With the weight and size savings, you can expect a single pallet of Fast 2K to replace 20 pallets of concrete. And, each bag can be stored and used outside in both summer and winter temperatures as high as 38C (100F) and as low as -30C (-20F). StrongerFast 2K Deck is designed to adhere to wood, vinyl and metal posts, as well as the ground better than traditional concrete. It even binds to itself with ease. Additionally, Fast 2K Deck's versatile formula is completely waterproof and hydrophobic (as opposed to concrete, which absorbs water). It prevents water from getting into the seams of each post, thereby decreasing expected rot, rust, deterioration, and other water-related damages. FasterStop forming, pouring and curing concrete. Each bag of Fast 2K Deck mixes in 30 seconds and sets within 15 minutes, allowing installers to start mounting hardware in record time. And, with ingredients contained in a single two-pound bag, setting up and striking is convenient and quick, allowing you to complete the job without the need for moving crews, equipment, or concrete. SaferFast 2K Deck is both safer for both the environment and the user. No harmful chemicals are released into the environment when in use. And, switching to Fast 2K Deck can help cut down on injury from moving heavy supplies and handling potentially harmful ingredients.

## Questions & Answers

**Q: Could this be used to fill a plaster of Paris mold?**
A: Not that I'm aware of, it doesn't really say on the package but it does sit up very fast and is very durable. Sorry but that's the best I can answer your question.

**Q: Could this be used to hold an 8x8 supporting a substantial weight?**
A: I had to replace a 4x4 post for my mailbox and used this 2K Post Back Fill. I already had a deep hole in the cement, so this stuff fills up the gaps beautifully all around and keep the post solidly planted. I'm not sure about 8x8, weight is not the issue here but you would need a "solid" hole like in my case to hold to post, then this foam would then fill up any gaps. Good luck.

**Q: Can this be used to form the deck list foundation where the 8x8 post then sits on top held by a bracket anchored in the foundation?**
A: No, Fast 2K can only be used for installing posts that are sunk into the ground.  It cannot be used as a foundation material nor can any brackets be anchored into it.

**Q: Would this be good to use for posts for a horse fence strong and sturdy?**
A: Yes, also sets up quick and should be good for a horse fence.
