Why does the putty need to be left to stand for 5 minutes after opening the slurry?

1. Due to the presence of a certain proportion of high molecular polymer and other dry powder additives in the putty, these materials must be fully water-soluble to activate their properties, achieving a more ideal outcome. 2. The fine powder particles require a certain amount of time to absorb water. 3. Reducing the formation of bubbles.

Insufficient putty strength, causing powdering (dust-off).

Reasons: 1. Improper water addition. 2. Excessive back and forth scraping. 3. High absorbency of the base surface. 4. Hot or dry weather. 5. Uneven putty mixing.

Solution: 1. Add water according to the proportions in the instruction manual during opening. 2. Master the application method to minimize re-skimming. 3. Wet the substrate before application and perform maintenance after completion. 4. Wet the substrate before application and perform maintenance after completion. 5. Mix the putty thoroughly following the mixing instructions.

During the putty application process, the paste dries quickly.

Reasons: 1. Inconsistent slurry mixing, without allowing the slurry to settle after mixing. 2. Excessive water added at the initial stage of opening the slurry, resulting in insufficient water absorption by the powder during the blending process. 3. High moisture absorption rate of the base surface or hot, dry weather.

Solution: 1. Use an electric mixer to blend the mixture thoroughly, ensuring that the powder at the bottom and corners of the bucket is well-mixed until uniform and free of lumps. Allow to stand for 5 minutes before gently stirring before use. 2. Do not add too much water at the beginning of the slurry process. If the slurry is too thick, add a small amount of water to adjust the consistency. 3. Moisten the base surface before application.

After putty scraping, there are pores or bubbles present.

Reasons: 1. Gas introduced into the slurry during mixing. 2. Fine powder material tends to produce bubbles easily. 3. The base is relatively dry or has a high water absorption rate. 4. Inadequate time interval between the two coats, i.e., the first coat is not fully dried before the second coat is applied.

Solution: 1. Allow the powder mixture to settle for 5 minutes. 2. Pre-moisten the base surface if it is relatively dry. 3. Wait for the previous layer to be slightly dry (about 2-4 hours) before applying the next layer. 4. To remove air holes after applying the putty, simply press with the trowel against them.

Section 5: Cracks in the Putty Layer

Reason: 1. Significant surface deformation or cracking of the base layer. 2. Inadequate cleaning of the base surface. 3. Too thick of a single coat applied. 4. High temperatures or dry weather causing the base surface to be too hot, leading to rapid drying of the putty layer. 5. Over-thick application of putty in a single coat.

Solution: 1. Secure the base or repair cracks in advance. 2. Clean the sub-base thoroughly. 3. Avoid applying too thick a coat each time. 4. Moisten the base appropriately before construction to lower its temperature. 5. Each layer of putty should be 0.5-1mm thick, with a total thickness of no less than 1mm.
