Two-Pack Vs Single Pack

Two Pack Polyuretahne mixing

You won't believe why people are so afraid of two-pack. It's they don't know how to mix it.

It's really quite simple. There is a Part A and a Part B.

The Part A is the Sticky Plastic. You don't want to spill that on you because it is annoyingly STICKY!

The Part B is the Hardener.

Now there is no need to get cute. More is not necessarily better. So stick with equal parts.

The simplest method is to get an old ice cream container. The 2 litre ones.

You pour 2 litres of A into the container. Then empty that container into your large coating bucket.

Then you pour 2 litres of Part B, into your ice cream container. Then empty that container into the large coating bucket that has the 2 litres of Part A in it.

Now swirl the bucket. And or stir with your brush. Give it 2 minutes to sit, and you're set.

Now you cannot tell me that was difficult?

How much to mix?

The above mix of 2 litres of Part A and 2 Litres of Part B give you a 4 litre mix, which should coat approximately 40 M2.

So you get a spread rate of 10 M2 per litre of mixed product. So if you wanted to coat 120 M2 of floor (A whole house) you would need to mix 6 Litres of Part A and 6 litres of Part B.

Giving you 12 litres of product, which should coat 120 M2, with 1 coat.

Why Two-Pack is better than Single Pack?

It used to be a lot harder and a lot shinier. But with improvements in single packs, there isn't the vast difference there used to be. Single pack have bridged the gap.

However 2 pack still is Superior..........Why.....Atmospheric conditions.

Single pack is moisture cured. Meaning it relies on the moisture in the air to set. What happens if there is too much moisture in the air? Well you shouldn't put single pack on when its raining or about to rain. You can get some nasty effects that I won't go into in this article.

However because Two-Pack is chemically cured, meaning the Part B starts to set the mix off as soon as it is mixed, it doesn't rely on the weather to set it.

Therefore Two-Pack is far superior.

Oh and don't worry, you have about two hours to use the mixture before it starts to thicken. Its not going to go hard in the bucket after 10 mintues. LOL

Obviously you pour out any remaining.

Single pack usuers state, that they prefer single pack as they return any unused to the drum. However you shouldn't do this. As the polish you pour in the bucket has been air rated and exposed to air and moisture. Your now putting that moisture back in the drum, and esentially you are telling the entire drum its time to dry.

So single pack has a shelf life or around 6 months. If unused it goes hard in the drum. This process is sped up if you return unused portions to the drum.

Thus Two-Pack is superior. The A and B remain seperate.

So don't be scared of Two-Pack just because you have to mix two things together. Its just like mixing cordial and water. However you need equal parts, and don't drink it.
