We added a hydrophobizer to the tile adhesive instead of a latex additive. How critical is this?

Help me understand the consequences of a mistake:

When finishing a plastered facade with clinker tiles, the tiler mixed up the canisters and as an additive to the Litokol tile adhesive (blue, for exterior and interior work) was using Litolast (water-repellent impregnation (hydrophobisator) for joints between tiles and mineral substrates) instead of the special additive Latex Col-M (latex additive for cement-based adhesive mixtures.

Approximately 30 – 50 m2 he laid like this. What are the possible consequences during use?

• tile adhesive
• litocol
