Wall decoration is an integral part of home renovation, not only a crucial component of basic home decor but also a project that showcases taste.  While many focus on the final decorative effect of the walls, the quality of the base layer treatment is often overlooked.  However, the quality of base layer treatment directly affects the stability and durability of wall decoration.

Many people pay attention to the appearance of the walls during renovation but easily overlook the careful treatment of the base layer.  Improper handling or the use of inferior fillers in the base layer may lead to problems such as peeling, cracking, and alkali rebound after the completion of decoration, causing potential troubles later on.

To avoid such tragedies, it is crucial to have some relevant knowledge.  Next, we will briefly introduce the methods and techniques of interior wall putty, hoping to provide useful information.

1. Requirements and Treatment of the Base Layer

Surface Treatment: The base layer surface should be dry, sturdy, and smooth.  If the smoothness is insufficient, plaster gypsum can be used for leveling.

Cleaning Treatment: Dust, dirt, and oil stains on the new wall surface should be cleaned.  For old walls, loose, peeling, and powdery parts need to be thoroughly removed.

Mold Source Solution: Serious mold growth areas should be identified, and bleach water should be used for cleaning.

Priming to Seal the Base Layer: If primer is used to seal the base layer, ensure that the primer is completely dry before putty application.

1. Putty Powder Mixing

The mixing ratio of putty powder is 1:0.4-0.5 (powder to water).  It needs to be thoroughly stirred.  On-site construction can use an electric drill mixer, adding water or powder as needed until a uniform, particle-free paste is formed.  The putty mixture can be used after sitting for 10 minutes.

III.  Putty Application Process

Repairing the Base Layer: Use plaster gypsum to repair indentations and gaps on the wall surface and sand the protruding parts after drying.

Base Layer Cleaning: Ensure that the plaster layer is dry and firm, and remove dust, dirt, and mortar streaks.

Scraping Internal and External Corners: When applying putty, ensure that internal and external corners are clear and straight.  Use an aluminum alloy rod to repeatedly press and form external corners, while a special tool is used for internal corners.

First Two Layers of Putty Application:

First Layer Full Putty Application: Apply putty to fill tiny sand holes and shrinkage cracks, ensuring a compact, smooth, and neatly angled surface.

Second Layer Full Putty Application and Polishing: Before applying the second layer of putty, ensure that the bottom layer putty is completely dry and polished smooth.  The second layer should be applied perpendicular to the previous one, and the wall requires further filling.  When the putty is 6-7 parts dry, use a rubber scraper for pressing and smoothing, ensuring a smooth, straight, and evenly colored wall surface.

Final Putty Application:

Final Smoothing: When the wall is 7-8 parts dry, use a trowel to level the scratches and smooth the surface.

Polishing: After the final putty layer is dry, use sandpaper with a grit above 300 for polishing to ensure a smooth wall surface.

Priming or Painting: After the wall is completely dry, apply primer or paint.

1. Construction Indicators

Drying Time: Surface dry in 4 hours, fully dry in 48 hours.

Putty Unit Consumption: 1-1.5kg/sqm.  Actual usage may vary due to different construction methods and wall smoothness.

1. Precautions

Paint the putty-finished wall with latex paint within a month to avoid powdering and chalking issues.

Waterproof putty powder and non-waterproof types have essential differences in construction processes and should not be mixed.  Utensils used in construction should not be cross-used.

The strength of waterproof putty is higher, requiring polishing within 36 hours;  otherwise, the strength and polishing difficulty will increase over time.

For pH values below 10, there is no need to brush alkaline-resistant primer;  direct application of latex paint is sufficient.  For pH values between 11-13, apply alkaline-resistant primer to prevent paint from blooming.

By following the correct wall base treatment and putty construction process, you can ensure a durable and aesthetically pleasing wall decoration, creating a comfortable and pleasant living environment.  We hope these methods and techniques help you achieve better results in your renovation.

Moreover, incorporating Kingmax Cellulose into your putty mixture can enhance its performance.  Kingmax Cellulose, with its superior thickening and stabilizing properties, can improve the workability and adhesion of the putty, resulting in a smoother and more consistent application.  Additionally, Kingmax Cellulose contributes to better water retention, reducing the risk of drying to
