The Importance of PVC Flooring Installation and Self-Leveling Construction

With the increasing popularity of PVC flooring in the global construction market, the importance of professional installation is becoming more and more important. As a FARFLY technical team in the field of PVC flooring manufacturing for 18 years, we will analyze the key points of self-leveling construction.

Second, foundation testing and preparation standards

According to ASTM F710 specification requirements, three key tests need to be carried out before construction:

1. water content test: using CM method of measurement, the water content of the concrete substrate needs to be ≤ 4.5%.

2. Leveling test: Measured using a 2-meter straightedge, height difference between any two points ≤ 3mm.

3. Compressive strength verification: C20 and above concrete grade (≥20MPa).

Crack repair technical specifications

For different types of cracks to take graded treatment program:

1. micro-crack treatment (<0.3mm): adopt epoxy resin penetration repair.

2. Structural crack treatment: V-shape grooving → grouting → surface grinding.

3. Expansion joint treatment: It is recommended to keep the original expansion joint position and use elastic caulking adhesive.

Four, the golden rule of interface agent construction

1. Optimal coating volume: 0.2 - 0.3kg/m² (adjusted according to the porosity of the base surface).

2. Drying time: about 2-3 hours at 25℃ ambient temperature. 3.

3. Acceptance standard: finger touch test without sticky feeling, water permeability <0.5ml/min.

V. Key parameters for environmental control

Material proportioning and construction technology

Adopt German DIN 18560 standard mixing program:

1. Water-cement ratio control: 1:4 is recommended (refer to product description).

2. Mixing technique: Forced mixer ≥ 300rpm for 3 - 5 minutes.

3. Dumping technique: keep 30cm continuous dumping belt to avoid material stratification.

Seven, the more common construction error cases

1. premature walking problem: premature walking leads to surface indentation (need to wait 16 hours to harden).

2. local blistering phenomenon: local blistering phenomenon (defoaming roller needs to go back and forth more than 3 times).

3. Edge warping problem: Edge warping problem (reserve 8 - 10mm expansion joints).
