I do not know. I had not seen that vid but others with Yousef showing same thing.
You seem to have some construction or engineering knowledge background? (Sorry some don't! so more complete info provided)
Therefore, you are likely fully aware that we now have many water soluble, LIQUID, concrete and geopolymer product sealants readily available on the market.
IF the ancients had worked out the basics of a geopolymer stone mix ( not that difficult once the formula was found eventually from natural ingredients) THEN development of a sealant would be even easier, as it is closely related.
The active ingredient is an Acrylic Polymer based on an ester.
An ester "Usually, esters are derived from a carboxylic acid and an alcohol. Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of the main classes of lipids, and making up the bulk of animal fats and vegetable oils" Sorry just wiki ref
In the geopolymer spray on concrete the ingredients are alkaline but the acidic sealant bonds and makes it much harder durable and shine!
I am NOT suggesting the Serapeum boxes themselves were man made NOR geopolymer (but HOW were they cut, some are 13 feet long? - That requires a stupendously long impossible copper saw/ sand rubbing gadget)
It would not surprise me if AE had worked out some sort of an alcohol/ plant (Olive or palm oil) or animal fat mix, which bonded like a glaze.
Obviously they did!, as Yousef is pointing it out!
They had worked out artificial stone too , but maybe not as much use, as some claim?
