Preparation

Ensure that all surfaces are clean, sound and free from grease. Clean surfaces with Geocel Universal Cleaning Wipes

• Clean all joints of loose dust, dirt, laitance, old sealants and other contaminants, which could impair adhesion.
• Metal surfaces should be cleaned and degreased by wiping with a solvent (e.g. methylated spirits) impregnated, oil and lint free cloth.
• On brick and concrete, lightly dampen the surface with water prior to application.

NOTE: When using solvent always ensure adequate ventilation. Avoid heat, sparks and open flames. Observe and follow all precautions listed on solvent container label.

Application

If possible test on a small area before you start to ensure compatibility.

When used in conjunction with most common construction substrates, a primer is not required.

• The joint should be “tooled” within five minutes of application to ensure good contact between the sealant and the substrate.
• Smooth surface lightly with a damp cloth after application. Tooling of the sealant also gives a smooth, professional finish.
