Key Factors To Consider When Selecting A Primer For Your New Cement Floors

To ensure appropriate adhesion and the durability of the flooring system, choosing the suitable primer for new cement floors (สีรองพื้นปูนใหม่, which is the term in Thai) is crucial. The overall performance and durability are improved by the primer’s function as a bonding agent between the concrete surface and the topcoat.

Read on to know the significant factors to take into account when choosing a primer for your new cement floors.

Surface Preparation

It is essential to properly prepare the concrete surface before using any primer. Make sure the floor is spotless and clear of debris like oil, dust, and other impurities. Use the appropriate patching materials to fix and level the surface if there are any cracks or flaws. This will produce a uniform and smooth surface for the primer.

Type Of Primer

The choice of primer will rely on the particular needs of your project and the variety of primers that are now on the market. Common kinds include:

  • Water-Based Primers: These are easy to use and release fewer fumes. They are environmentally safe and ideal for the majority of interior uses.
  • Solvent-Based Primers: These primers are frequently suggested for outdoor or high-traffic areas since they have great adherence. However, they could release potent fumes, therefore enough ventilation is crucial when applying.
  • Epoxy Primer: Primer made of epoxy resin offers the best adhesion, chemical resistance, and durability. They are perfect for places with lots of foot activity, including factories or commercial buildings.
  • Acrylic Primer: This type of primer is adaptable and may be used indoors or outside. They have strong adherence and are simple to apply.
  • Moisture Barrier Primers: If your concrete floor has moisture issues, consider using a moisture barrier primer to prevent any moisture-related problems in the future.

Compatibility With Topcoat

Make sure the primer you select is appropriate for the topcoat you want to use. For best adhesion, certain topcoats, such epoxy, polyurethane, or acrylic, may call for particular primers. Consult the topcoat’s manufacturer’s instructions before choosing a primer, and vice versa.

Porosity Of Concrete

When selecting a primer, it is essential to take the concrete’s porosity into account. To guarantee appropriate bonding, very porous surfaces would need a primer with sufficient penetration. Choose a primer with improved surface adherence if the concrete is generally smooth and non-porous.

Drying Time

If you’re on a tight timetable, pay attention to the primer’s drying time. A primer that dries quickly might help shorten the duration of the endeavour as a whole.

VOC Content

Volatile Organic Compounds (VOCs) are chemicals that can evaporate into the air, potentially causing health and environmental issues. Select a primer with a low VOC content if you are working on an interior project or a job that requires consideration for the environment.

Manufacturer’s Recommendations

Always abide by the suggestions and instructions for the primer provided by the manufacturer. They have put their items through testing and are the experts on how to get the desired outcomes. For details on application, coverage, and surface preparation, refer to respective technical data sheets.

Remember that choosing the right primer for new cement floors is a critical step. Taking the time to research and select the appropriate primer will result in a durable, long-lasting, and visually appealing cement floor.
