Pelto White Silicone Sealant + Caulk Gun + Caulking Tool Kit - All-Purpose 100% Silicone Caulk (10 oz Tube), with No-Drip Gun, 3-in-1 Scraper/Smoothing Tool, Multi-Use Handheld Finishing and Scraping Tool

A practical, all-in-one caulking kit that actually makes the job easier

I put the Pelto caulking kit through a few real projects: re-caulking a fiberglass tub surround, sealing a kitchen sink seam, and closing up a daylight gap around a through-the-wall A/C sleeve. As a package, it promises a lot—100% RTV white silicone, a no-drip gun with a higher thrust ratio, and a 3‑in‑1 scraper and smoothing tool with multiple pads. After a weekend of use, I’m convinced the kit earns its keep for most DIY sealing tasks, with a few caveats worth knowing before you buy.

What’s in the box

• 10.1 oz tube of white 100% RTV silicone
• No-drip caulking gun with a smooth-acting trigger
• 3‑in‑1 removal and finishing tool (corner scraper, straight scraper, and smoothing tool with five interchangeable angle pads)
• A compact multi-use finishing/scraping tool

You don’t need anything else to get started—other than painter’s tape, rags, and a solvent for cleanup. The silicone is an acetic-cure formulation (you’ll catch a mild vinegar odor), rated as waterproof, flexible, and same-day rain-ready. It’s not paintable, not intended for underwater or aquarium use, and should not be used on corrosion-sensitive metals such as copper, zinc, brass, or galvanized steel. For kitchens, baths, windows, siding, and general interior/exterior gaps on common building materials, it’s appropriate.

Setup and ergonomics

The gun is the unsung hero in most caulking jobs. Pelto’s gun is a lightweight, higher-thrust model that kept a steady feed with less hand fatigue than bargain-bin options. The drip control is effective: releasing pressure on the trigger tamed ooze at the tip better than many low-cost guns I’ve used. It’s not as stiff or refined as higher-end pro guns, but it doesn’t fight you.

The silicone tube loaded easily and the puncture of the inner seal was straightforward. The included tooling pads snap into the finishing tool without drama, and the corner and straight scrapers are sized sensibly for tub edges and countertop seams.

Surface prep and removal

The removal side of the kit matters as much as the caulk itself. The metal corner scraper bit into old, brittle tub caulk without skittering, and the straight scraper handled long runs along the backsplash. I found the corner blade aggressive enough to be effective but not so sharp that it gouged the gelcoat on my fiberglass surround—still, you want to keep a shallow angle and go slow near softer finishes.

One quirk: the sliding segment on the multi-tool doesn’t lock as firmly as I’d like. When bearing down on stubborn material, it can drift. It never stopped me from removing old sealant, but it required a little attention to hand position and pressure. If you’re working on a delicate surface, consider softening old silicone with a dedicated remover gel first; it makes the scraper’s job easier and reduces the risk of scuffs.

After scraping, I wiped with isopropyl alcohol to remove residue, then let surfaces dry fully. This step is non-negotiable with silicone; skin oils and soap scum are adhesion killers.

Laying a bead: consistency and control

The silicone in this kit has a medium viscosity—thicker than most painter’s caulks but on par with quality 100% RTV sealants. In practice, it flowed predictably. On my tub, I ran a 3/16-inch bead and had no gaps or sudden surges. The higher-thrust gun helps keep motion smooth, and the tack time strikes a nice balance: enough open time to correct your line, but not so much that it slumps.

The smoothing pads are genuinely useful. I swapped among the five profiles to match joint width: a tighter radius for narrow seams around a sink and a broader profile along the tub ledge. Beads finished cleanly, and the pads left a uniform surface comparable to what a pro would do with a practiced fingertip—without the mess. I still prefer to tape long, visible runs for crisp shoulders; with tape, the results looked sharp and consistent.

Odor was mild (that classic acetic vinegar note) and dissipated quickly with ventilation. Skin-over happened within minutes, and I treated cure time as a day or two depending on bead thickness and humidity. For exterior trim around the A/C sleeve, I had light rain a few hours after application and saw no issues, which tracks with the “same-day rain-ready” claim.

The tools: where they shine and where they don’t

• Scrapers: Effective at removing old silicone and construction adhesive residue. The corner scraper in particular is well-shaped for tub/wall joints. The metal is not super thick, so use a controlled hand. The straight scraper’s edge wore a little after a lot of use, as expected for this class of tool.

• Smoothing tool with pads: The star of the kit. If you struggle to maintain bead shape, these pads give repeatable, pro-looking results and reduce cleanup.

• Multi-use finishing/scraping tool: Handy as a secondary piece, though the sliding section could use a firmer detent. I got best results using it as a light-duty finisher and a backup scraper, not the primary remover.

• Caulking gun: Smooth and predictable. It’s not a contractor-grade tank, but it’s better than most throw-ins. The frame welds on mine were tidy, the thrust mechanism engaged consistently, and the drip control actually worked. I’d happily use it for silicone, latex, or hybrid sealants.

Adhesion and durability

On glazed tile, fiberglass, stainless steel (sink flange), primed wood, and vinyl trim, adhesion was solid. After curing, the bead remained flexible with no shrink-back and no cracking. In the bath, it’s holding up to daily splashing and cleaning; around the exterior sleeve it’s shrugging off sun and temperature swings so far. For anything that needs paint later, choose a paintable acrylic or hybrid sealant instead—silicone won’t take paint, and you’ll regret trying.

One caution: silicone shelf life is finite. If a tube feels unusually stiff or won’t flow smoothly even under steady pressure, it may be past prime or incompletely punctured at the inner seal. Check the date code when you open it; fresh silicone should lay a continuous bead without gritty bits or sudden resistance.

Where it fits best

• Re-caulking tubs, showers, and sinks
• Sealing kitchen backsplash and counter-to-wall joints (white finish)
• Weather-sealing window and door trim outdoors (where white is acceptable)
• Small exterior penetrations and utility cutouts where flexibility matters

Where it’s not a match:
- Joints you intend to paint (use paintable caulk)
- Underwater or aquarium applications
- Direct contact with copper, zinc, brass, or galvanized steel (use a neutral-cure silicone or a compatible sealant instead)

Tips for best results

• Prep is everything. Remove all old caulk, degrease, and dry completely.
• Cut the nozzle to the smallest opening that will fill the joint. It’s easier to add than to remove.
• Keep the gun moving and maintain steady pressure. Let the thrust do the work.
• Use painter’s tape for visible lines, tool the bead once, then pull the tape while the silicone is still wet.
• Choose the smallest smoothing pad that fully bridges the joint. Fewer passes make for a cleaner finish.
• Ventilate during cure and give it at least 24 hours before heavy water exposure.

Value and build quality

For an all-in-one kit, the Pelto package offers good value. You’re getting a usable gun, a capable scraper, a flexible finishing system, and a full-size tube of white silicone. The individual pieces aren’t premium, but they’re functional and thoughtfully chosen. My gun held up and the mechanisms worked as expected; the scrapers showed normal wear after a couple of projects. If you’re caulking every day, a pro-grade gun and a dedicated stainless scraper will feel better and last longer. For occasional home projects, this kit checks the right boxes.

The bottom line

The Pelto caulking kit simplifies the parts of caulking that most DIYers struggle with: removing old material thoroughly and laying a neat, consistent bead. The silicone performs like a proper 100% RTV should—flexible, weather-resistant, and quick to skin—though remember it’s not paintable and not for corrosion-prone metals. The gun is better than typical bundled guns, and the smoothing pads elevate the finish.

Recommendation: I recommend the Pelto caulking kit for homeowners and DIYers who want a practical, ready-to-go setup for bathrooms, kitchens, and light exterior sealing. It delivers steady application, helpful tooling, and dependable silicone without fuss. If you need paintable joints, daily professional durability, or compatibility with copper/galvanized metals, look elsewhere; otherwise, this kit is a straightforward way to get clean, durable results on common sealing tasks.
