Block paving gaps

[Gnarly_Gnasher]

Hello

I have just cleaned my garden block paving.

I want to fill the gaps in.

I know the proper way is kiln dried and a sealant. But that is very expensive.

Is there a lower cost option for filling in the gaps?

Thanks

No. Use proper stuff.
Yes. Everything had gone up.

Try buying from a patio/gravel merchant vs diy
