TPI PRIMER MB – Two-component epoxy moisture-resistant primer

TPI Primer MB
Two-component, solvent-free epoxy primer

TPI PRIMER MB DESCRIPTION

TPI Primer MB This is a two-component, solvent-free, low-viscosity epoxy resin-based moisture-resistant primer. It is used as a primer for concrete surfaces in areas where complete drying is not possible before applying an epoxy floor coating.

TPI PRIMER MB APPLICATION

TPI Primer MB Suitable for use in the following applications:

• Primer for concrete, cementitious, and epoxy plaster substrates when it is not possible to wait for the material surface to dry completely.
• Use to prevent moisture from rising onto the concrete floor surface.
• Moisture-resistant primer for epoxy flooring systems.

Advantages of TPI Primer MB

• 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.

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 >= 4.5%, use a primer. TPI PRIMER MB.
• If the surface moisture content is < 4.5%, use an epoxy primer. TPI Primer FS.

Mixing sequence:

• TPI Primer MB 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 3 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 MB.
• For concrete with high porosity, two layers should be applied. TPI Primer MB (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

• Do not replace the liner with another product.
• The primer must be applied evenly to the surface.
