    Evening guys. I am going to screed my extension floor and was wondering what sharp to OPC ratio to use. 3 sharp to 1 OPC, or 4 sharp to 1 OPC? Also any additives needed? I am going to use fibres in the mix, but was wondering about additives also. Thanks guys.

    I am no pro builder but when I used to help a builder the mix was always 3 sharp 1 OPC with no additive.

    3-1 or 4-1 is fine make sure you seal the concrete first with pva or better still sbr.also wear over pants as the burn it great ..once floated run a steel trowel over it.
