- Strong Bond: Once set, the posts felt rock solid, which gave me peace of mind that the fence would stay put through wind and rain.
How to Use Sika Post Fix: My Step-by-Step
- Prepare the Hole: I dug a hole around the post area, making sure it was deep and wide enough for stability.
- Mix the Mortar: I mixed the Sika Post Fix powder with water according to the instructions until I got a smooth, workable consistency.
- Position the Post: I stood the post in the hole, ensuring it was level and at the right height.
- Pour and Pack: I poured the mix around the post, packing it firmly to eliminate air pockets.
