Primer, ultrabond, dehydrator: what's what
The section is small — 16 items from ten brands — and almost the entire choice comes down to two words in the name. The main one is “acid” or “acid-free.”
Acid or acid-free
There are four acid ones here: LUNAmoon Acid Primer 13 ml, KODI Primer 10 ml, ADORE Acid primer in 8 and 15 ml. All the rest are labeled as acid-free. Distinguishing them by name is simple: acid ones have the word “Acid” or “кислотний”; acid-free ones have “Ultrabond” or “безкислотний.” The “Property” filter in the left column only helps halfway: it has only one value “Acid-free,” so acid ones cannot be filtered out that way — you’ll have to spot them by eye.
Why “ultrabond” and “acid-free primer” are the same
In this catalog, these terms appear on the same listings. SHELLY, ADORE, and KODI write “Ultrabond … Acid-Free Primer” in one line; LUNAmoon writes “Ultrabond, Acid-Free Primer”; EDLEN leaves no room for interpretation: “Ultrabond (primer) acid-free.” HEYLOVE, TOUCH, NOTD, and DNKa’ use only the word “ultrabond” — it’s the same format, just without the second label. So if you’re looking for an acid-free primer, look for ultrabond: in this section they are synonyms.
The spelling does vary: HEYLOVE splits it into two words — “Ultra Bond”; DNKa’ writes “ультрабонд” in lowercase; NOTD uses only Latin letters. Because of this, a site search using one spelling variant may not show some listings — it’s safer to go into the section and view all sixteen items together.
Dehydrator: a separate function
Primer and ultrabond work as adhesion; a dehydrator dries the nail plate. There are two items for it in the section: NOTD Dehydrator 10 ml and MOON FULL Ultrabond + Dehydrator 2-in-1 8 ml, where the manufacturer combined both functions in one bottle. Both items are popular and often out of stock — check availability on the item page. A broader selection of cleansers and dehydrators in various formats is in the neighboring section.
Volume: 8, 9, 10, 12, 13 or 15 ml
Packaging here is small — from 8 to 15 ml — and the “Volume” filter gives exactly these six values. Two brands let you avoid mixing manufacturers: ADORE offers both formats in two sizes (Ultrabond 8 and 15 ml, Acid primer 8 and 15 ml), and LUNAmoon offers both at 13 ml. KODI separates them by volume: acid primer only 10 ml, ultrabond only 15 ml. The smallest bottles are 8 ml from ADORE and MOON FULL; the largest are 15 ml from HEYLOVE, TOUCH, ADORE, and KODI.
What’s nearby
Before primer comes degreasing — that’s cleansers and dehydrators; for cuticles separately there are cuticle removers, and after polymerization — liquids for removing the sticky layer. All auxiliary liquids together are in the Spesia Liquids section, and comparing one manufacturer’s range is convenient on the brands page.
For application order, curing time, and compatibility with the base, refer to the instructions for the specific bottle: they differ among brands.
