For formwork spray application, if the material inside the formwork is mortar, spray it at the same time!

Hello, everyone.

This is Enta.

Do you spray the mortar separately for the formwork and inside the formwork?

Or are you playing together?

How do you take a finished product measurement?

They're different jobs, so they're different, right!?

 

That's a common topic of conversation.

As long as you check the depth of the formwork when you assemble it beforehand, there shouldn't be any problems with the finished shape, right?

And since we'll be taking as-built measurements of the spray thickness, I don't think there will be any problems.

 

Let's say we play them separately.

So what happens then?

Naturally, that connection will be severed.

 

When a connection is severed, it means that part becomes independent.

What will be the result?

Mortar within the frame

Do you understand?

Lines have appeared along the edges of the formwork and in the mortar inside the formwork, and efflorescence is developing.

 

Every time it rains, the concrete undergoes carbonation and gradually loses its strength.

That means it won't have a long service life.

 

Forget about those silly quirks and just play it all in one go!

As long as the spray thickness is sufficient, there will be no problems.

If there is a problem, it’s that in some cases the frame is made of mortar and the interior is concrete.

It would be best to either change everything to mortar or get approval for that.

 

As far as I know, nothing like that was ever pointed out to me during any of my checkups.

If anyone has any feedback, please leave a comment. (This will help me improve and learn for the future.)

 

See you later.
