"I use the same two products on every client, and it's only ever caused a problem once." That's a comment we hear a lot, and it's usually said in frustration, not as a boast. If your go-to routine works on 19 out of 20 clients, it's easy to assume the 20th client is the problem.

She isn't. That client's nails are simply telling you something the other 19 didn't need to.

Understanding the scenario

Let's say the routine is: Stick 'n Float as the rubber base, Lastik Plus as the builder. It works consistently — until it doesn't. To understand why, it helps to understand what each product is actually doing, and why this particular combination has been holding together without primer on most clients.

Stick 'n Float is Planet Nails' highest acid-based rubber base. That acid content gives it exceptionally strong inherent adhesion — which is exactly why it performs so well on oily, sweaty, or problem nail plates. It also means that for many clients, the Stick 'n Float itself is doing some of the work that primer would normally do. That's not a reason to skip primer — it's the reason skipping it hasn't caused a visible problem yet on 19 out of 20 clients.

When the 20th client turns up with a problem, there are three possible reasons — and it may be one, or it may be all three:

1. Primer was skipped before the rubber base. Primer — Sticky Bond or another PN primer — is applied to the natural nail before the rubber base. Its job is to remove surface oils and prepare the nail plate to accept product. Stick 'n Float's acid content provides strong adhesion for most clients, but not every nail plate. The 20th client may simply be a nail plate that needs that extra step.
2. Stick 'n Float may not be the right rubber base for this client. Because Stick 'n Float's adhesion molecules have a small molecular weight, sensitive clients can still react to it. For a client whose nail plate doesn't respond well to the acid-based adhesion in Stick 'n Float, switching to Lastik or Lastik HF as the rubber base — which use a different adhesion chemistry — may solve the problem entirely. Lastik HF in particular has the largest molecular weight adhesion molecule of all three rubber bases, making it the least likely to cause a reaction in sensitive clients.
3. Lastik Plus may be too rigid for this client's nails. Lastik Plus is a builder gel with built-in base adhesion properties. It cures harder and more firmly than standard Lastik, which is exactly what makes it great for clients who need structure and durability. But on clients with naturally thin, brittle, or flexible nails, that rigid cure fights the nail's natural movement rather than working with it — and lifting follows. The product itself isn't the problem; it's the match between product and nail type.

Matching PN systems to the client in your chair

Here's how the core PN rubber base and builder range actually differs — so the choice isn't guesswork:

Why PUGGLE has changed the hard gel conversation

PUGGLE's growth reflects a genuine shift toward hard gel, and it's easy to see why. It offers file-off strength and durability in a fluid, brush-on bottle format — and for technicians who are used to BIAB-style application, the familiar brush-in-a-bottle feel makes the transition to hard gel far less intimidating. That crossover appeal is a big part of why PUGGLE has resonated so strongly.

What's worth understanding is that PUGGLE can be used on any client as a hard gel builder — for overlays, tip overlays, infills, and sculptures — in the same way you would reach for PUG or Fortify. Its self-levelling formula makes a no-file or minimal-file finish possible when the client's nail shape allows it. When shape correction or filing is needed, you file as normal. The no-file result is a bonus the formula makes possible, not a requirement for choosing it.

Choosing between soft gel, hard gel and everything in between

One of the most common points of confusion is when to reach for a soft gel versus a hard gel — and the answer is less about product preference and more about what the client's nails actually need.

For short nails needing flexibility: Lastik is the go-to. It flexes with the nail, supports thin and brittle plates, and works as a rubber base, a builder, or both. If more structure is needed on a short nail and the client still wants soak-off, Lastik Plus is the step up — but only if the nail plate can handle a firmer cure. For short nails needing hard gel durability, PUG, PUGGLE, or Fortify all work — the choice comes down to application style and finish preference.

For medium to long nails: Lastik's flexibility becomes a limitation — it won't support medium or longer length builds. Lastik Plus handles medium length soak-off builds. For anything requiring more durability, or for longer extensions, PUG, PUGGLE, or Fortify give you the hard gel strength those lengths need.

On wear time: soft gel systems — Lastik, Lastik HF, Lastik Plus — generally wear to around the three week mark, and infills at three weeks are recommended. Hard gel systems — PUG, PUGGLE, Fortify — can stretch to four weeks on the right client, though individual wear time always varies.

A simple way to check before you default to habit

• Are you following the manufacturer's recommended application steps? Planet Nails recommends primer be used before the rubber base in most cases. It's worth checking you're working to the brand's protocol rather than a shortcut seen on social media — not every nail plate will show a problem straight away, but some will.
• Is Stick 'n Float the right rubber base for this client, or the default? It's our strongest acid-based rubber base and brilliant for oily or problem nail plates — but it's not the recommended starting point for everyone. Lastik is.
• Is this nail naturally soft and flexible, or firm and strong? Lastik suits the former; Lastik Plus or a hard gel suits the latter — but only if the nail plate can handle the firmer cure.
• How long are the nails? Lastik has a length limitation. Medium and longer builds need Lastik Plus at minimum, or a hard gel for maximum durability.
• Does the client want soak-off or file-off? That's often the clearest fork in the road — soft gel for soak-off, hard gel for file-off.
• Is this client HEMA-sensitive, or unconfirmed? Use the HF range for confirmed sensitivity — not as a blanket default.

Twenty clients, twenty nail plates. The routine that works for most of them is a great default — not a rule that overrides what any individual client's nails are telling you.
