Learn Polish: Ja bynajmniej nie umiem lepić, a na dnie jest duże pęknięcie. - I by no means know how to mold, and at the bottom there is a large crack.

In standard Polish, bynajmniej (by no means / not at all) is used to strongly emphasize a negation, so it almost always pairs with a negative verb like nie umiem. Native speakers sometimes mistakenly use it to mean przynajmniej (at least) in positive sentences, but grammatically, bynajmniej requires a negative context.

Why use the conjunction a instead of i for the word 'and' here?

The conjunction a is used to show a light contrast or a shift in focus between two clauses. Here, it shifts the focus from the speaker's lack of skill (nie umiem lepić) to the existing flaw in the object (duże pęknięcie). Using i would merely list two unrelated facts, whereas a connects them to frame the situation: I cannot fix it, and besides, it is already broken.

What exactly does the verb lepić mean in this context?

The verb lepić means to mold, shape, or stick things together using a pliable material like clay, dough, mud, or snow. You would use it when talking about making pottery, building a snowman (lepić bałwana), or forming pierogi.
