I have a 3-week-old concrete slab that was made with simple means resulting in a slant at some point which means the sill will not fit as it should.
I would appreciate tips on some form of cost-effective compound, mounting adhesive, anchor compound, or whatever that can be pressed into the irregularities that exist between the concrete slab and the sill, in order to achieve an even load on the sill and the entire structure. Pouring leveling compound is not an option as I don't have time to wait another 2 months.
Grateful for timely and relevant tips.

Don't know how much and uneven it is, but to saw/plan, sand a plank that follows the irregularities and use as a spacer.
Coarse concrete. Can't get cheaper. Mixed to damp earth consistency and spread out where the sill is to be placed. Dries in a day or so.
There are fillers with various formulations that are usable after just a day or so. Whether you should use self-leveling or hand-applied filler depends on the surface area needing filling and the thickness of the layer. Hand-applied filler goes down to 0 mm while self-leveling needs a few mm. Check with your building supply store to see what they sell and recommend, but not with the low-cost chains as they lack the expertise on this issue.Björkås22 said:
Ardex has good products but they are priced accordingly.
An alternative to filler is expanding concrete, which goes down to 10 mm. Regular concrete, as mentioned earlier, is cheap but not a good idea as it is not meant for thin layers.
Wood shims can also work.
