Why DIY Bathtub Reglazing Fails
We fix failed DIY refinishing jobs every week. Here's why 68% of DIY jobs fail within 2 years — and how to avoid the same mistakes.
The 8 Reasons DIY Refinishing Fails
We see these mistakes every week. Here's what goes wrong.
Inadequate Surface Prep
The #1 cause of failure. Even tiny amounts of soap scum, body oil, or cleaning residue prevent adhesion. Consumer cleaners aren't enough. Pros use acid etching and industrial degreasers.
Using the Tub Too Soon
Kits say "use in 24-48 hours" but full cure takes 7 days. Using the tub during soft-cure damages the coating. Most DIYers rush this step.
Thin Consumer Coatings
DIY kits are 1-2 mils thick. Professional coatings are 5-8 mils — 3-5x thicker. Thin coatings scratch, chip, and wear through faster.
Wrong Temperature/Humidity
Epoxy needs 60-80°F and low humidity to cure properly. Too cold, too hot, or too humid and the chemical reaction fails. Pros control environment.
Coats Applied Too Thick
Thick coats trap solvents, causing bubbles, peeling, and improper curing. Multiple thin coats are essential — but hard to achieve with roller.
Skipping Sanding
Glazed surfaces are too slick for coatings to grip. Thorough sanding (or acid etching) creates adhesion. Many DIYers underestimate this step.
Dust and Debris in Finish
Bathroom dust settles on wet coating. Pros spray in controlled conditions and know how to prevent contamination. DIY often has texture issues.
Low-Quality Kit Materials
Most kits don't include primer or true 2-part epoxy. They cut costs by using single-component coatings that don't bond properly. Pros use industrial 2-part epoxy systems with proper primer — and can do touch-ups ($80-$120) if issues arise. With DIY, you can't touch up — you strip everything and start over at DOUBLE the cost.
The True Cost of DIY Failure
Stripping failed DIY costs DOUBLE a normal refinishing job

DIY Failure FAQs
Can I just touch up peeling spots?
No. Once peeling starts, it will spread. The adhesion has failed. You must strip the entire coating and start over. Patching peeling areas doesn't work — the patch will peel too.
How do I strip failed DIY refinishing?
Use chemical strippers designed for epoxy (like Citristrip). It's messy and time-consuming. Many people try to scrape it off — this damages the underlying surface. Professional stripping is more thorough.
My DIY job looks fine now. Will it last?
Maybe. The first 3-6 months often look good. Problems typically appear around the drain first (most wear), then spread. If you followed all steps perfectly, you might get 2-3 years. But most fail sooner. DIY vs professional
Should I try DIY again or go pro?
Go pro. You already spent money on DIY. Trying again risks the same failure. Professional refinishing costs $600-850 with a 5-year warranty and 10-15 year lifespan. It's the more economical choice now.
