Most Ridgefield garages are under ten years old. That is the easiest slab to coat and the easiest one to get wrong.
Free In-Home EstimateA new slab in Pioneer Canyon or Taverner Ridge looks perfect. Machine-troweled, no cracks, no oil. Two things are hiding in it. First, the builder almost certainly sprayed a curing compound on the surface, and that film has to be ground off or nothing will bond to it. Second, concrete poured in the last two years holds more water than anything else in the county, and Ridgefield slabs fail moisture tests more often than any other town we serve.
So the job here is not about repair. It is about testing and removal. We put a calcium-chloride or RH probe on the floor before quoting a system, and we prep the whole slab by diamond grinding or dustless shot blasting, picked for the space, to take the curing compound off and open the pores. Twenty minutes up the freeway gets us to the Junction or Hillhurst, so the moisture test the day before install is not a problem to schedule.
If the moisture reading is high, we do not walk away and we do not coat anyway and hope. We prime with a moisture-mitigating epoxy that tolerates the vapor coming through, then build the standard flake floor on top of it. Without that step, a fresh Ridgefield slab pushes water into the coating over the first wet winter and you get bubbles by spring. With it, the same slab holds for the life of the 5-year workmanship warranty.
The system over the primer is what it is everywhere: 100% solids epoxy for the base, flake broadcast until the floor will not hold another chip, and a polyaspartic topcoat that holds up to hot tires, spilled gas, and the road grime that comes in off Pioneer Street. Ridgefield is open and flat, a bit windier than Camas, so garages here take a lot of sun through the door. A spilled quart of oil comes up with a rag and some degreaser. Polyaspartic does not.

Ridgefield grew faster than almost any city in Washington, and most of that growth is 2015 to 2024 houses with 2 and 3-car garages from Gee Creek up to Ridgefield Junction. Those slabs are smooth and flat, but the moisture and curing-compound issues are real and we test every one. The exception is Old Town Ridgefield near the Ridgefield National Wildlife Refuge and Lake River, where 1900s to 1960s houses have small, thin, cracked garage floors that need polyurea and old paint removal instead. Late spring through early fall is the best window for a new slab here. Twenty minutes up I-5 from our shop, so we come out often.

Every slab is different, so we price each floor after a free in-person inspection. New builds in Ridgefield mostly have 2-car garages at 400 to 500 square feet or 3-car at 600 to 750. If the probe says the slab needs a mitigating primer, that adds to the price, and we tell you before scheduling. Slab condition, old coatings, cracks, moisture and size are what move the price, and exact pricing comes after that inspection, with a written quote.
Inside the coating
Every floor starts with a properly prepared slab and is built up one layer at a time, each with a specific job.
For concrete floors
Maybe, maybe not. Concrete under a year old is often still too wet, but some slabs dry faster than others. We meter it. If the reading is under the limit, we proceed with the standard system. If it is over, we either wait a season or add a moisture-mitigating primer, and we will tell you which we recommend.
It is a spray builders put on fresh concrete to slow drying so the slab cures stronger. It leaves a thin film that repels water and repels epoxy. Most Ridgefield slabs from the last decade have it. We take it off by diamond grinding or dustless shot blasting, picked for the space. Acid etching does not remove it, which is why kits fail on new garages.
Yes. A smooth machine-troweled finish is the worst surface for adhesion because the pores are closed. Grinding opens them so the 100% solids epoxy can lock in mechanically. It does not hurt the slab. The finished flake floor is smoother and easier to clean than the bare concrete was.
We do. Those are a different job: thin 1900s to 1960s slabs with cracks and often paint. Crack fill, full grind, and a moisture test because there is no vapor barrier under them. The finished floor looks the same as one in a new subdivision, just with more prep behind it.
About 20 minutes north on I-5 from our shop, so it is a routine drive. We usually do the moisture test at the estimate, grind and base coat on day one, and topcoat on day two. Foot traffic can start a day or two after the topcoat, and the cars stay out about a week while it reaches full cure.
Moisture test included.
