How is Fast 2K a cost saving product is a question we get asked a bit. On the face of it, it seems that it is more expensive than concrete and sometimes Rapid Set on gram for gram basis (in some places it is more expensive and in some places it is less).
But Fast 2K is not just a concrete or Rapid Set concrete replacement – it is a whole new category of post fix in a category all of it’s own. We found this post on an a forum from a sign post installer that explains perfectly the cost benefits.
Think of the weight, time and labour savings... especially if you're installing posts somewhere that doesn't have a water supply.
1kg a bag that turns into 45kg of concrete... so one bag is the equivalent of 2 bags of post mix and 11 litres of water.
So for the sake of argument, lets say you're installing 2 posts that would usually require 4 bags of post mix and 22 litres of water. Plus you have to carry a wheel barrow, tools for mixing etc.
The weight would be around 115kg.
With Fast 2K, you'd have 2kg in weight instead. Plus you don’t have to dig a hole as big so you’re spending less time and effort on digging too.
As a weight and space saver alone it’s worth its weight in gold, but it also means there is no waiting around while the post mix takes hold. You have 30 seconds of play before it starts to set... a few minutes later it's solid. Post mix is nowhere near as quick.
Cost wise... Fast 2K works out at $21.95 per 1kg bag (full retail price – discounts apply for trade accounts), so that's about $10.50 per post... Rapid Set retails for between $7 and $12, depending on where you buy it, so $14 - $24 for two bags making it equivalent to Fast 2k.
And that isn’t taking into account the labour and time savings.
You're lugging 20kg bags of post mix about and 22 litres of water, when you've got a product that weighs no more than a big bag of sugar and it sets faster. If I’m charging on a project basis and I can reduce my labour by more than half, that’s got to be good for my bottom line.
