Postmix - 20KG bag

Our 20KG postmix bags are a pre mixed blend of cement, sand, aggregates and specially selected additives to accelerate the curing time.

Super simple to use... simply add water to your pre dug hole and add the postmix, no mixing required.

The postmix will then set hard in 5-10 minutes and will fully cure after a few hours depending on weather conditions.

Ideal for fixing concrete, timber and metal posts in place.

Supplied in water resistant bags.
