Notes

  • Pay attention to different treatment methods for various gaps, hollows, oil stains and dampness, etc.

  • The fiberglass cloth must fully cover the base layer (overlapping by 10cm) without any wrinkles or bulges.

  • The divider strips should be installed firmly, accurately positioned, and with straight lines. Check the flatness with a level.

  • The proportion of paint aggregates must be accurate. Aggregates that are damp or discolored are not allowed to be used.

  • Stir the materials according to the spreading speed. The materials must be thoroughly mixed. When spreading by color separation, wait until the previous layer of materials is completely cured.

  • When laying the material, use a straightedge to check the flatness. If there are any concave parts, replenish the material in time.

  • When laying materials of different colors, the dark-colored materials should be laid first.

  • If it is found that the materials are insufficient during the laying process, stop immediately. Install the divider strips and wait for the second batch of materials to arrive before laying again.

  • When laying the material, reserve the grouting material


Technical Statement

Our company can design construction plans of different specifications (thickness, effect, etc.) through flexible matching and combination of various products to meet the personalized requirements of all kinds of customers. To ensure that your project can select the appropriate floor system, please consult our professional technical advisors. However, when using our company's products, please strictly follow the construction process, dosage requirements and precautions of the product. Otherwise, our company will not bear any responsibility for the quality of the project or any losses.



Construction conditions

  • The moisture content of the substrate surface is less than 8%

  • Relative humidity ≤ 80%

  • Dew point temperature: The substrate and the substrate of the uncured coating must be at least 3℃ higher than the dew point temperature to reduce the risk of condensation or mottling of the ground coating

  • For specific details, please refer to the construction plan.
