What Is Sika Post Fix?
Sika Post Fix is a rapid-setting concrete alternative designed specifically for fixing posts in the ground. It’s a powder that you mix with water, and it sets quickly—usually within 15 minutes. I found it very convenient compared to traditional concrete, especially when I needed a fast and durable solution.
Why I Chose Sika Post Fix
I chose Sika Post Fix because of its quick setting time and ease of use. Unlike traditional concrete that takes hours to cure, Sika Post Fix allowed me to finish my fencing project much faster. It also requires less mixing and cleanup, which saved me time and effort.
Key Features I Noticed
- Fast Setting: Sets in about 10-15 minutes, allowing me to stand the post quickly without waiting all day.
- Durability: Once set, the post felt very secure and stable, even in wet weather.
- Water Resistant: It can be used in damp or wet conditions, which was perfect for my garden where the soil tends to retain moisture.
- Easy Application: I just added water to the powder in the hole and mixed it with a stick. No heavy mixing equipment needed.
- Versatility: Worked well for wooden, metal, and concrete posts.
Things To Consider Before Buying
- Setting Time: While fast, you need to work quickly once mixed, so prepare your posts and tools beforehand.
- Quantity: Make sure to buy enough for your project. Each bag covers a specific volume, so calculate the number of posts you need to fix.
- Mixing Instructions: Follow the water-to-powder ratio exactly for the best results; too much water can weaken the set.
- Storage: Keep the product dry before use, as moisture can cause it to harden prematurely in the bag.
- Environmental Conditions: Extremely cold weather can slow setting times, so plan accordingly.
How I Used Sika Post Fix Step-by-Step
- Dug the post hole to the required depth.
- Placed the post in the hole, ensuring it was level and plumb.
- Pour the Sika Post Fix powder around the post in the hole.
- Added water gradually while mixing the powder and water with a stick.
- Tamped the mixture lightly to remove air pockets.
- Held the post steady until the mixture began to set (about 10-15 minutes).
- Backfilled the remaining hole with soil after the mixture was firm.
