Bull floats

[cwr]

Hi folks

With a floor slab for a garage / outbuilding to be poured next week I'm looking at bull floats. There appear to be different sizes available, 1200 x 300, 1200 x 200, 900 x 200, etc.

 

Any advice on a good size to use on a 10m x 5m floor slab, or is it as much personal  preference?

 

Thanks

I've never tried one, but often observed. Professionals will tend to have the biggest as there are fewer passes and lips. But these were handled by very strong guys. My hunch is to use the small size for control.

 

There was always a lot of shovelling and shaping pre bull float.

This was usually a pump mix concrete which is easiest to move around. What is your plan?

As I must have said 20 times before... do not add water.

 

Thinking more, isn't a tamp finish more appropriate? In which case the tool of choice is a straight piece of 4x2.

Smaller sizes can leave bigger lips, as the weight of the pole has a smaller surface to distribute on. 

 

Keep the twist gentle to adjust the angle for the pull and you shouldn't create suction dents or bubbles. 

 

They are surprisingly quick to get to grips with. Most the issue is trying not to bash the handle on things with the draw back. That leaves a dent.

The smaller ones are hand floats Hire a 1200 and a swivel pole

We cast a bit of concrete couple of days ago. This is just a test piece.

Do these bull floats get a really good finish on the surface?

Have you thought about using self levelling concrete, CEMEX have Evolutuon.

About 300kg.

The size we want will be about 700kg.
