TPI PRIMER SB – Two-component solvent-based epoxy primer

TPI Primer SB
Solvent-based two-component epoxy primer

TPI PRIMER SB DESCRIPTION

This is a two-component, solvent-based epoxy resin primer with low viscosity. It is used as a primer for concrete surfaces before applying epoxy floor coatings.

TPI APPLICATION PRIMER SB

Suitable for use in the following applications:

• Primer for concrete, cementitious screed, and epoxy screed surfaces.
• Suitable for surfaces with low to high absorbency.
• Primer coat for epoxy flooring systems.
• Binder for self-leveling mortars and plasters.

ADVANTAGES OF TPI PRIMER SB

• Easy to install, short construction time.
• Non-toxic. Solvent-free, so it should be used in restricted areas.
• Its low viscosity allows for good penetration.
• Excellent adhesion.

INSTRUCTIONS FOR USE

Surface preparation:

• The concrete surface must be solid and have a minimum compressive strength of 25 N/mm² and a minimum adhesion strength of 1.5 N/mm².
• The surface must be clean, dry, and free of contaminants such as dirt, oil, grease, old coatings, and surface maintenance compounds.
• Weak concrete and dirt must be removed. Surface defects such as pits, voids, cracks, and bumps must be treated and smoothed.

Check for moisture levels and apply the primer:

• Check surface moisture, relative humidity, and dew point before application.
• If the surface moisture content is < 6%, use an epoxy primer. TPI Primer SB.
• If the surface moisture content is >= 6%, use a moisture-resistant epoxy primer. TPI Primer MB.

Mixing sequence:

• TPI Primer SB It is supplied in a two-component kit consisting of a base component A and a curing agent B.
• Before mixing, stir ingredient A thoroughly. Once all of ingredient B has been added to ingredient A, continue mixing for 5-20 minutes until a homogeneous mixture is achieved.
• Do not mix for too long to reduce air entrainment.
• Use a low-speed stirrer (300-400 rpm) or other suitable mixing equipment.

Applying the primer layer:

• Ensure the primer is applied completely and continuously to the substrate surface.
• For concrete with low/medium porosity, a single layer can be applied. TPI Primer SB.
• For concrete with high porosity, two layers should be applied. TPI Primer SB (in directions perpendicular to each other).
• It can be applied using a brush, a short-bristle roller, or a trowel.

Toilet:

• Clean equipment and tools immediately after use. Once the paint has hardened, it can only be removed by mechanical means.

Important note:

• Construction is not permitted. TPI Primer SB Up onto the surface where the moisture content increases.
• Do not replace the liner with another product.
• The primer must be applied evenly to the surface.
