The Importance of Vapor Barriers

Have you ever admired a sleek, shiny floor in a hangar or a stylish showroom and wondered about the secret behind its flawless finish? Let me introduce you to the unsung hero of many flooring projects – the vapor barrier.

• Epoxy Primer Moisture Vapor Barrier - Premium Quality Coating System

Vapor barriers are the shield that protects your floor from the invisible nemesis – moisture and gases that sneak through porous concrete. Without this protection, you run the risk of bubbles forming beneath your floor.

These bubbles not only disrupt the smooth finish but may also turn into unsightly potholes upon curing and drying.

Consider vapor barriers as a robust armor, holding back an impressive 20 pounds per square inch of pressure from gases and moisture alike. It's a step you definitely shouldn't skip if you're aiming for a floor that's as durable as it is attractive.

Prepping the Floor: Clean, Fill, Repeat

First things first, let's get that floor ready for its transformation. Here's how it goes:

1. Cleaning is a no-brainer, especially in dusty areas like airport hangars. A thorough blowout removes as much dirt and dust as possible.

2. The next important step is filling any cracks and divots. Believe it or not, our go-to material is body filler – yes, the same kind used in car body repairs! It's budget-friendly, works marvelously, and best of all, it cures quickly so you can keep moving forward with no delay.

3. I recommend using a bondo spreader and a precise technique – press down to fill the crack, then skim off the excess. This prevents unnecessary sanding later on.

Applying the Vapor Barrier: Strategy is Key

Alright, onto the central part of today's tutorial – the vapor barrier application process. We're using a top-notch product that covers about 500 square feet per kit. Here are some pro tips when working with vapor barriers:

• Divide and Conquer: Use tape to mark out sections on the floor to manage your workflow.

• Measure Twice, Pour Once: Ensure you mix up only as much as you can spread quickly. Small batches are your friend if you're working solo.

• Patience Pays Off: Rushing might feel like saving time, but it often leads to do-overs. Take your time.

Mixing the Magic Potion

When it comes to mixing your two-part A, one-part B vapor barrier, precision is key. A minute or two of thorough mixing is essential – you want a homogenous mix without air pockets for the best finish.

The Pour and Spread

Once mixed, we pour the material in parallel lines across the pre-segmented floor section. The next weapons of choice are a squeegee and an 18-inch roller.

The goal is to spread the barrier thinly and evenly, first with the squeegee and then cross-rolling with the roller to ensure we don't miss a spot.

Pro-tip for a Perfect Spread

Overlap slightly between sections; don't stop abruptly at the dividing line. This will help you avoid creating visible lines on the floor.

A Quick Hack for a "Polished Concrete" Look

If time or resources don't allow for a full polished concrete process, the vapor barrier can be your quick fix. Apply it post-grinding for that glossy, durable finish – a cheater's version of the polished concrete that still looks fantastic.

Vapor Barrier Application is Finished

After finishing the vapor barrier application, what remains is a smooth canvas ready for the next steps in your flooring project, be it adding color or laying down a clear coat.
