LEMAX PRIMER SB

LEMAX PRIMER SB – BITUMINOUS PRIMER 40% CONTAINING TECHNICAL SOLVENTS

ESCRIPTION

Lemax Primer SB is a bituminous solution that contains oxidized bitumen and pure, quick-drying solvents. What makes this product truly exceptional is its remarkable characteristics: it exhibits excellent adhesion and penetration properties upon application, dries quickly, and, most importantly, lacks the dreaded stickiness that can hinder construction projects.

APPLICATION

Lemax Primer SB is a versatile product that finds its place in various aspects of construction:

• Dust Blocker and Porosity Minimizer: Use it as an undercoat to mitigate the effects of dust and reduce the porosity of concrete surfaces. This prepares the surface for the seamless application of polymer bitumen membranes, whether via hot flame application or cold application with bituminous glues.
• Waterproofing Champion: Count on Lemax Primer SB as a waterproofing coating for concrete walls. It ensures that moisture doesn’t stand a chance.
• Versatile Fixer: This primer is a jack of all trades when it comes to fixing surfaces. It’s perfect for cement, wood, and metal surfaces.
• Protective Shield: In addition to its primary functions, Lemax Primer SB can also be used as a protective film for tubes and metal tanks.

For the best results, ensure that the concrete surfaces you intend to treat are as dry as possible, clean, and free from oils and chalking powders. You can apply Lemax Primer SB with ease using a brush, roller, or spray. However, for hot flame applications of polymer-bitumen membranes, it is crucial that the concrete surfaces are impeccably dry. If not, consider using a specific bituminous primer for wet surfaces.

The drying time typically ranges from 1 hour after application. If the primer is applied in high thickness, the substructure’s temperature is low, or the surface is not very absorbent, the drying time can extend to 2-4 hours.

ADVANTAGES

Lemax Primer SB boasts a range of advantages that make it an indispensable tool for construction projects:

• Excellent adhesion and penetration properties for robust surface preparation.
• Quick drying ensures that your project stays on schedule.
• Absence of stickiness means less mess and smoother work processes.

CONSTRUCTION INSTRUCTIONS

Note: Before you begin, ensure that you have taken all necessary safety precautions, including wearing appropriate personal protective equipment (PPE) and working in a well-ventilated area.

Surface Preparation:

• Make sure the concrete surfaces you intend to treat are dry, clean, and free from any contaminants such as oils, grease, or chalking powders. Remove any loose debris or dust using a brush or suitable cleaning method.
• Repair any cracks or imperfections in the concrete surface using appropriate concrete repair materials and allow them to cure fully before proceeding.

Product Inspection:

• Check the Lemax Primer SB product packaging for any signs of damage or tampering. Ensure that the product is within its shelf life.

Application Tools:

• Select the appropriate application tool based on your project needs. You can use a brush, roller, or spray equipment for applying Lemax Primer SB.

Mixing (if required):

• Lemax Primer SB is ready to use, so you typically do not need to mix it. However, if the product instructions indicate otherwise, follow the specified mixing guidelines carefully.

Application:

• Apply Lemax Primer SB evenly over the prepared concrete surface. Be sure to maintain a uniform thickness. For hot flame applications of polymer-bitumen membranes, ensure the surface is perfectly dry.

Drying Time:

• The drying time may vary based on several factors, including the thickness of the primer, the temperature of the surroundings, and the absorbency of the concrete. Generally, the primer dries within 1 hour from application. However, in specific conditions, it might take longer, up to 2-4 hours. Ensure that the primer is completely dry before proceeding with the next steps of your construction project.

Cleanup:

• To clean the tools used for application, such as brushes or rollers, use a common synthetic or mineral diluent. Follow the manufacturer’s guidelines for disposal and handling of cleaning materials.

Additional Coats (if required):

• Depending on your project’s specifications, you may need to apply multiple coats of Lemax Primer SB. If so, ensure that each coat is applied uniformly, and allow adequate drying time between coats.

Safety Precautions:

• Throughout the application process, adhere to safety guidelines. Use the appropriate PPE, and maintain proper ventilation in the work area. Follow all safety precautions provided on the product packaging and in the product’s safety data sheet.

Quality Assurance:

• Periodically inspect the treated surface to ensure that the primer is properly applied and has dried completely. Address any issues promptly to maintain the integrity of your construction project.

Remember that these construction instructions are provided as a general guideline. Always consult the specific product guidelines and recommendations provided by the manufacturer. Proper surface preparation and application techniques are essential to ensure the best results with Lemax Primer SB and to contribute to the success of your construction project.
