What Causes Fish Eyes or Bird's Eyes in Floor Finish?

Understanding Fish Eyes or Bird’s Eyes in Floor Finish: Causes and Remedies

Fish Eyes, commonly referred to as bird’s eyes, can be a perplexing issue in floor finishes.

Definition of Fish Eyes (Bird’s Eyes)

Appearance

Fish Eyes are small circular imperfections that become visible in a floor finish once it has dried. These circular formations disrupt the smooth and uniform appearance of the finish.

Causes of Fish Eyes

Excessive Coating Thickness

Applying overly thick coats of finish can lead to fish eyes. The weight of the excessive finish may cause the formation of these circular imperfections during the drying process.

Agitation During Application

Excessive agitation or stirring during the application of the finish can introduce air into the product. When this air is trapped and cannot escape, it results in the formation of fish eyes.

Substrate Preparation

Improper preparation of the substrate (the surface receiving the finish) can contribute to fish eyes. Contaminants or inadequate cleaning of the substrate may interfere with the proper bonding of the finish.

Remedies for Fish Eyes

Optimal Coating Thickness

Ensure that the coats of finish are applied within the recommended thickness. Following manufacturer guidelines for application thickness can help prevent the occurrence of fish eyes.

Gentle Application

Apply the finish without excessive agitation. Minimize stirring or agitation to reduce the introduction of air bubbles into the finish.

Thorough Substrate Preparation

Adequate cleaning and preparation of the substrate are crucial. Ensure that the surface is free from contaminants, dust, or residues that could compromise the finish’s adhesion.

Quality Control Measures

Quality Finish Products

Invest in high-quality floor finish products that are formulated to minimize common issues such as fish eyes.

Application Training

Provide training for individuals responsible for applying floor finishes. Proper application techniques can significantly reduce the likelihood of imperfections.
