Saw cuts can be filled, in a pinch with a product like Dap concrete joint filler. However, these products can shrink causing a crack in the coating later.
Again, in a pinch, customers have relied on "Bondo" for small pop-outs.
Naturally, cutting corners beneath the coatings can come back to bite you so tread carefully.
We recommend that the "prep products" we offer be used as we know they work.
