Polyaspartic garage floor in West Palm Beach
SFL Epoxy is a guide run by Terragroupe, LLC. We do not install anything and we are not booking jobs yet.
In West Palm Beach, the 6 a.m. air sits within one polyaspartic data sheet's dew point margin on 160 days per year1. A fast cure helps only if the start day fits that margin. Ask the installer how the slab and the dew point are checked on the day.

Polyaspartic garage floor in West Palm Beach: local facts
| Fact | Value | Source |
|---|---|---|
| Highest monthly mean dew point of the year at West Palm Beach Intl Airport (USW00012844) : NOAA 1991-2020 hourly normals, relevant to the dew-point margin on polyaspartic data sheets (vendor) | 74.3 F (Aug) | [1] 1991-2020 |
| Days per year when the mean of the 24 hourly normal dew points is 70 F or higher at West Palm Beach Intl Airport (USW00012844) | 139 days per year | [1] 1991-2020 |
| Days per year when the 6 a.m. normal air temperature is within 5 F of the normal dew point at West Palm Beach Intl Airport (USW00012844) , the margin a polyaspartic data sheet (vendor) requires between substrate and dew pointThis count is sensitive: summer 6 a.m. air is within a few degrees of the dew point at all three stations, so a 0.1 F change moves it by about 20 days. Compare stations loosely; slab temperature in a garage differs from airport air. | 160 days per year | [1] 1991-2020 |
Hybrid systems, layer by layer
A hybrid system has a base coat and a clear polyaspartic topcoat. Ask which product goes in each layer. Ask too whether the base is epoxy or polyurea.
Each layer has a window for the next coat. The sheets we read say a missed window can mean sanding the surface before the next layer goes on. Ask who sets the schedule. Ask what happens if a storm or a muggy morning blocks the day you picked. A good scope names a fallback date and says who pays for a return trip.
Dew point and early mornings in West Palm Beach
At Palm Beach International Airport, NOAA's normals make August the muggiest month, with a mean dew point of 74.3 F (Aug)1. Muggy days are common: 139 days per year1 have a daily mean dew point of 70 F or higher.
The sheet sets limits for the day of the job. The slab must stay 5 F over the dew point 2. Humidity must stay at 75% or lower 2. We counted the mornings when 6 a.m. air falls inside that margin: 160 days per year1. Treat the count as a planning figure. Air is not slab, so the real test is a reading in your garage.
House, townhouse or condo?
As of October 18, 2026
In West Palm Beach, 50.5 percent3 of occupied homes are owner-occupied, and 38.4 percent3 of housing units are detached houses.
The city's permit FAQ answers differently for flooring in a house and flooring in an apartment or condo. It does not mention floor coatings 4. Check with the building department about your garage, and do not assume. Call Development Services and ask. The Building Division's main line is 561-805-67005.
What the vendor says, and what is untested
- Hot-tire marks: the sheet markets the topcoat for resistance to marking 2. We found no independent test.
- Sunlight: the same sheet claims UV resistance 2. Again, there is no independent data.
Ask each installer to write their own warranty terms on these points.
Reading the price
No quote from a West Palm Beach installer is on file yet. National guides show epoxy at 3-12 USD per sq ft6 and a kit seller (vendor) estimates polyaspartic at 7 USD per sq ft7 to 12 USD per sq ft7. The ranges overlap, so price alone does not decide it.

Ask to see the price in writing before work starts. Set it next to the labeled ranges on this site, so you can judge it. Nothing should start until you say yes. - A timing guide
Dry-season and early-morning windows, read against the maker's limits. The coat goes down when the weather allows it. - A warranty checklist
Ask for the written exclusions before you sign. Moisture, hot-tire marks, impact and fluids are the ones to ask about. - A permit and HOA one-pager
The office to call, the page to read and the papers to check for your city. Nothing should surprise you. - A photo habit
Take photos of the prep and of the finished floor, so you can see the result. - What to ask for in writing
Ask any installer to put the workmanship term in your written scope. We will publish an installer's term on this site if one signs.
This site is free to read. It sells no work and takes no payment. If your slab is not a fit for a coating, the score and the guides point that out. Any work is agreed in writing between you and the installer who does it.
Garage Floor Readiness Score
Answer each question. The score shows how much needs sorting out before a coating, and which answers added the most. It is a starting point, not a price or a promise.

Questions people ask
How soon can I drive on polyaspartic?
The topcoat sheet gives foot-traffic and full-cure times at 68 F 2. Garage temperatures run higher in summer. Ask for the wait for cars in your scope, in hours.
Is polyaspartic worth it for a West Palm Beach garage?
That depends on what you value: a quicker return to service, against claims that come only from vendors. Compare the written scope and warranty for each system.
Does a hybrid system need more than one visit?
It can. Each layer has its own wait and recoat window on the sheet. Ask the installer for the full schedule, with the weather limits, before you hire anyone.
