Mixing 2 different self level compounds??

[dabomb3k]

Hi guys, this might be a dumb question but I have a concrete floor which for the most part is quite level and will only need a couple mm levelling compound but there are certain sections of it that just drastically dip by up to 30mm

I noticed wickes currently have an offer on their compound at £9 a bag with discount

https://www.wickes.co.uk/Setcrete-Universal-Floor-Levelling-Compound---20kg/p/112754

But it only Does 3-6mm which is fine for most of it but not for the dips of 30mm

They also do a deep base version for up to 50mm which isn’t on sale at £20 a bag

https://www.wickes.co.uk/Setcrete-Deep-Base-Floor-Levelling-Compound---20kg/p/133780

Now naturally it’s gonna cost me double to use the deep stuff so I was wondering if I could mix up a bag or two of the deep stuff, pour it in the large areas and then before it’s dry use the universal leveller on the rest of the floor?

Anyone see any reason why not or
Offer me another solution?

Thanks in advance

yes, what you propose will work.
mix the SLC's seperatly.

believe me, when we were desperate weve thrown down all kinds of mixed stuff as floor levellers an fillers - no come backs .so far!
