How Encapsulants Seal in Odors When Removal Isn't Enough

Encapsulants are liquid barriers applied over surfaces that still hold odor after cleaning. They dry into a film that traps odor-causing molecules, stopping them from releasing into the air. This is useful when the material can't be removed, like a concrete slab or structural beam.

The coating works by physically blocking the odor source. It doesn't neutralize the smell chemically; it seals it away. For water damage, this means the musty or sour smell is contained, not eliminated. The pros often use this method after extraction and drying when odors persist.

The coating forms a continuous film that adheres to the surface. It can be applied with a brush, roller, or sprayer, depending on the product. Once dry, it creates a barrier that is impermeable to air, so odor molecules can't pass through.

Some encapsulants also add a slight odor of their own, but most are low-VOC and dry to a neutral finish. The key is proper surface preparation: the area must be clean and dry for the coating to bond. If moisture is still present, the encapsulant won't stick and odors will return.

• Seals porous surfaces like concrete and wood
• Prevents odor molecules from escaping
• Applies like paint with brush or roller
• Dries to a durable, washable film
• Right for areas that can't be removed

The process starts with a thorough cleaning and drying of the affected area. The pros remove any loose debris and ensure the surface is dry. Then they apply the encapsulant in thin, even coats, allowing each to dry completely.

Typically, two coats are recommended for even coverage. After drying, the surface is sealed and can be painted or finished. The odor should be significantly reduced. Keep in mind that the cost depends on the size of the area and the type of encapsulant, so it varies.

• Clean and dry the surface first
• Apply even, thin coats
• Allow full drying between coats
• Test a small area before full application
• Use two coats for even results
