How to Inspect a Reglaze Job Before the Contractor Leaves

By Tub Reglazing Directory Editorial Team · Updated 2026-09-30

Most homeowners stand in the bathroom doorway after a reglaze, glance at the tub, and think it looks fine. Then they pay, the contractor leaves, and 48 hours later they discover a run the size of a thumb on the far sidewall or a cluster of fisheye craters near the drain. Those defects were there when the contractor walked out. They just weren’t visible under flat overhead lighting to an untrained eye.

This is a fixable problem. A competent contractor will do their own final inspection before calling you in. But you should do yours too, before any money changes hands. The window is narrow, the technique is specific, and knowing what you’re looking for is what separates a homeowner who gets the job redone at no cost from one who files a BBB complaint six weeks later.

This article walks through that inspection: when it’s safe to do it, how to see defects that bathroom lighting hides, which problems demand an immediate fix, and how to protect yourself in writing if the contractor pushes back.

First: You Can Look Before the Coating Cures. You Just Can’t Touch Much.

There’s a persistent misconception that you have to wait 48 to 72 hours before checking anything. That’s the full cure window. It’s when you can run water and use the tub normally. It’s not when inspection starts.

Visual inspection can happen once the surface reaches what the industry calls tack-free: you can hold your hand a few inches above it and feel no tackiness, and the surface no longer looks wet. For most two-component coatings in a ventilated bathroom at room temperature, that’s roughly 1 to 2 hours after the final coat. Ekopel 2K’s technical data sheet specifies a touch-dry time of 4 to 6 hours at 68°F. Napco’s coating guidance puts tack-free at 1 to 2 hours under adequate ventilation. Product formulations differ, so ask your contractor to hand you the specific technical data sheet for whatever they used. That TDS is your reference, not a generic internet estimate.

The distinction that matters: you can look at the surface aggressively, from every angle, with a flashlight, right up close. What you should not do during the cure window is press, rub, or drag anything across the surface. A light fingertip test at one inconspicuous point to confirm tack-free is fine. Rubbing a hand across the tub to feel for texture is not.

One more thing before you go in. EPA guidance on isocyanate exposure is clear that two-component urethane coatings off-gas reactive chemicals for hours after application. OSHA 29 CFR 1910.94 establishes that solvent vapor concentrations in a small bathroom can remain elevated for 30 minutes to several hours post-spray, depending on ventilation. If your contractor used any prep strippers containing methylene chloride, OSHA 29 CFR 1910.1052 requires them to communicate residual vapor hazards to you before re-entry. The short version: make sure the bathroom has been actively ventilated before you walk in, and don’t linger if you can smell solvent. A window open and a fan running for at least 30 minutes after the contractor finishes spraying is a minimum, not a courtesy.

The Flashlight Technique: The Only Tool That Actually Works

Overhead bathroom lighting is almost useless for detecting surface defects in a fresh coating. It’s diffuse, it comes from the wrong angle, and it creates an even wash that masks the small shadows that reveal runs, fisheyes, and thin spots.

What works is raking light: a single-point light source held nearly parallel to the tub surface, around 5 to 15 degrees off horizontal. Think of how you’d hold a flashlight to read a coin’s embossing. At that angle, any surface irregularity casts a shadow. A drip that’s 0.5 mm tall becomes completely obvious. A fisheye crater that’s invisible from above becomes a small dark circle.

The science behind this is straightforward. ASTM D523 defines specular gloss measurement at multiple angles of incidence, and the principle is that angular changes in the incident light reveal variations in coating uniformity. The flashlight technique is a field approximation of that same principle. You don’t need a gloss meter.

How to do it: get a decent flashlight (your phone’s light works, but a small handheld with a tighter beam is better). Turn off the bathroom overhead light. Crouch or kneel at one end of the tub so you’re at eye level with the surface. Hold the flashlight close to the tub, nearly parallel, and slowly move it along each surface: the floor, each long wall, each short end. Then do it again from the other end. Move methodically. Spend 60 seconds on each panel.

Any area that looks different from its surroundings under raking light deserves a closer look.

What You’re Looking For: A Field Defect Reference

The [[Professional Refinishers in Brooklyn](../cities/brooklyn.html) in New York](../cities/new-york.html) Group defines several categories of finish defects in their best-practice documentation. Here’s what each looks like in the field and what it means.

Runs and drips show up as ridges or teardrop-shaped bumps, usually on vertical surfaces. They happen when the sprayer applies too much material in one pass or holds the gun too close. Under raking light, they’re unmistakable. A run that has fully cured becomes very difficult to remove without recoating that panel, which is why Napco’s technical guidance explicitly notes that defects are most visible and easiest to remediate in the first hour after application. If you see runs, say so now.

Fisheyes are small craters, usually circular, with a raised rim and a depressed center. They’re caused by silicone contamination, oil, or inadequate surface prep. They do not self-correct. The coating physically cannot bond to the contaminated spot, so the film pulls away from it. A surface with fisheyes needs mechanical remediation before any topcoat can adhere properly. This is a redo situation, not a “monitor it” situation.

Orange peel is a slightly dimpled texture that resembles the skin of an orange. Mild orange peel is a normal artifact of spray application and may smooth slightly during initial cure. The PRG’s quality standards treat it as acceptable in minor form. Heavy orange peel that looks rough even from a few feet away is not acceptable and should be flagged.

Pinholes and porosity are tiny holes in the coating film, often clustered. They indicate the substrate wasn’t properly sealed or the coating was applied too thin. Under raking light, porous areas look dull or matte compared to the surrounding gloss. This is a functional problem, not just cosmetic: moisture penetrating through pinholes will eventually lift the coating from underneath.

Uneven sheen (patches of dull or flat finish against high-gloss surroundings) usually indicates thin-film application in those areas. A properly applied refinishing topcoat should show consistent 60-degree gloss across the entire surface. Thin spots are also a safety issue: ASTM F462-79 specifies a minimum wet static coefficient of friction of 0.04 for bathing facility surfaces, and thin or non-uniform coating can fail that threshold.

Edge and Seam Coverage: Where Most Contractors Rush

Pay extra attention to four specific areas. These are consistently the most poorly executed sections of any reglaze job because they require careful masking removal and finish work around hardware.

The drain collar. Lean in and look at the inside edge of the drain ring where it meets the tub floor. The coating should wrap cleanly to that edge with no bare porcelain or fiberglass visible, no ragged line, and no buildup from masking tape that was pulled too late.

The overflow plate. The oval cover plate on the tub wall near the faucet end. Remove the plate during inspection if the contractor hasn’t already. The coating should extend cleanly under the plate rim. Many contractors mask right up to the plate edge and don’t finish the last centimeter. That bare strip will collect water and eventually delaminate the surrounding coating.

Caulk lines at the tub deck. IRC Section P2721 requires that joints between a bathtub fixture and surrounding surfaces be sealed with an approved sealant. A reglaze job that leaves the deck caulk joint open, cracked, or painted over rather than properly resealed has created a waterproofing gap. The caulk bead should be smooth, complete, and applied after the coating cured enough to accept adhesion. If the contractor applied caulk over uncured coating, it may not bond correctly.

The rim and top edge of the tub. The coating should wrap over the top edge or meet the wall tile cleanly at the rim. A coating that stops short of the rim leaves an exposed line that will begin lifting within months.

The Tactile Check: Minimal and Specific

Once you’ve done a complete visual pass with the flashlight, you can do a limited tactile check. The goal is to identify areas that feel soft, sticky, or inconsistent in texture, not to assess the whole surface.

With a light fingertip touch (no dragging, no pressure), check the tub floor in two or three spots. The coating should feel uniformly smooth. If one area feels tacky while others don’t, that spot may not be curing at the same rate as the surrounding coating, which can indicate a prep or mixing issue in that zone.

Check for surface texture consistency. If the floor feels smooth in one area and roughly textured in another, and you can see a corresponding difference in sheen, that’s a real inconsistency, not normal cure variation. Note the location.

Do not touch any area you’re not specifically checking. Do not rub. If you feel something abnormal, flag it verbally to the contractor before touching it again.

Documenting What You Find

Before you say anything to the contractor, photograph it. Phone cameras in 2026 are good enough to document any defect visible to the naked eye. Use your phone’s rear camera with the flashlight still in raking position: that angle will show the defect clearly in the photo.

Photograph the full tub from each corner, then individual defects with something in frame for scale. A pen or a coin next to a drip makes its size obvious in dispute resolution later.

The FTC’s consumer guidance is direct on this: payment in full can be interpreted as acceptance of completed work. If you pay before documenting defects, your leverage is almost entirely gone. The BBB recommends noting defects in writing on the contractor’s completion form, or in a separate written communication delivered to the contractor at the time of inspection. A text message with a photo attached and a clear description of the issue creates a timestamped record that will serve you far better than a verbal conversation.

If the contractor disputes your characterization of a defect, don’t argue in real time. Ask them to note on the completion form that you’ve raised concerns and that those concerns are under review. That notation is enough to prevent full payment from being treated as unconditional acceptance.

Also: before the contractor leaves, photograph the product label or ask them to write the product name and batch number on the receipt. Many refinishing warranties, which typically run 1 to 5 years, are voided if you use the wrong cleaning products. Knowing what coating is on your tub lets you check the manufacturer’s care instructions and preserves any future warranty claim.

What You Can Let Go and What You Can’t

Not everything you spot requires a redo. Very mild orange peel texture on the tub floor, no visible drips, no fisheyes, and consistent sheen across all surfaces: that’s an acceptable finish job by PRG standards. Monitor the orange peel through the first 72 hours; if it smooths out noticeably as the coating fully cross-links, it was normal spray texture.

Anything structural is different. Fisheyes, hard runs, visible pinholes, areas of uneven sheen that correspond to thin coverage, bare spots near the drain or overflow plate: these will not improve with cure time. The coating’s chemical cross-linking is locking in whatever surface geometry exists right now. Remediation gets significantly harder with every hour that passes, and Napco’s technical guidance states that explicitly.

If you find non-self-correcting defects, tell the contractor clearly, show them the photos, and ask what the remediation process is before you let them leave. A reputable contractor will know what’s fixable with a light sand and touch-up coat versus what requires stripping that panel and starting over. Ask which it is. Get the answer in writing, or at minimum in a text message sent while they’re still on site.

The contractors worth hiring will tell you the truth. The ones who say “it’ll look better when it cures” about a hard drip are either misinformed or hoping you’ll go away. You now know enough not to.

Frequently Asked Questions

How long should I wait before inspecting a freshly reglazed tub?

Visual inspection can happen once the contractor confirms the surface is tack-free, typically 1 to 2 hours after the final coat under good ventilation, though some coatings like Ekopel 2K take 4 to 6 hours to reach touch-dry at 68°F. Don’t touch or press the surface during this window. Full cure for most two-component coatings takes 48 to 72 hours, and that’s when water exposure is safe.

What defects will not fix themselves and require the contractor to redo the work?

Fisheyes (crater-like depressions caused by silicone or oil contamination), hard runs or drips, visible pinholes, and any area with inconsistent sheen that doesn’t resolve in the first hour will not self-correct. Orange peel texture that is mild may smooth slightly as the coating cures, but anything structural requires mechanical remediation.

How does the low-angle flashlight technique work?

Hold a flashlight nearly parallel to the tub surface rather than pointing it straight down. At that shallow angle, surface variations cast small shadows that become clearly visible. This field method approximates the angular gloss-detection principle described in ASTM D523 and reveals defects that overhead lighting completely misses.

What should I document before making final payment?

Photograph every defect with your phone, note the defects in writing on the contractor’s completion form or in a text or email sent to the contractor before you pay. The FTC notes that full payment can be interpreted as acceptance of the work, so written documentation before payment is your primary protection.

Are drain and overflow plate areas really that commonly skipped?

Yes. These areas require careful masking removal and finish work around hardware, and rushed contractors cut corners there more than anywhere else. Check the inside edge of the drain collar, the rim of the overflow plate, and the caulk bead at the tub deck. All three are priority inspection points.

Does a reglazed tub have to meet a slip-resistance standard?

ASTM F462-79 (Reapproved 2015) specifies a minimum wet static coefficient of friction of 0.04 for bathing facility surfaces, and that threshold applies to refinished tubs. A coating defect that creates a smooth or glazed patch can lower friction below that threshold, which is both a safety concern and a potential warranty issue.
