Exterior waterproof paint for walls and construction projects in general is a fairly comprehensive and effective protection method nowadays. Thanks to its special waterproofing properties, waterproof paint can protect the project from mold, leaks, and also bring aesthetics. So what is the best type of waterproof paint for walls? What are the common construction methods for exterior waterproof paint and walls, and indoor ceilings to achieve the best waterproofing effect? Let’s refer to Weifangsenke in the article below.
What is waterproof paint?
Waterproof paint is a type of paint that has waterproofing properties to help prevent leaks on the surface of a building due to the impact of harsh weather conditions such as rain and sun. It is a water-based chemical compound with strong chemical bonds combined with adhesive compounds to form a paint film that can protect the surface of structures such as exterior walls, floors, concrete roofs, etc. This helps to prevent leaks in the building, ensuring the aesthetics and long-term durability of the structure.
Advantages and Applications of Waterproof Paint
Ease of Application: Requires minimal preparation: simply clean the surface, dampen it, and apply the waterproof paint mixture according to the manufacturer’s instructions. Allow it to dry and apply two or three more coats as per the paint’s specifications.
Variety of Types: Diverse range with unique purposes: some combine two or three functions, such as waterproofing, sun protection, and algae resistance. This versatility can save time and money.
Suitable for Numerous Surfaces: Applicable to various areas of residential and commercial buildings, from waterproofing bathrooms, floors, roofs, and swimming pools to exterior walls. Its versatility makes it ideal for both residential and commercial applications.
Catering to Diverse Needs: Exterior waterproof paints come in a wide range of types and functions to meet the specific needs of customers, including those seeking both waterproofing and aesthetic enhancement.
Each type of waterproof paint serves a different purpose, preventing water penetration on horizontal, vertical, upward, and inward surfaces, acting as a sturdy protective layer. Waterproof paint shields your home from the detrimental effects of weather.
Utilizing waterproof paint from the start of construction enhances the durability of the building’s structure. This contributes to the longevity of the structure, minimizing future repair costs associated with water damage and subsequent waterproofing treatments.
Classification of Waterproof Paint
Classification by base component
Cement-based waterproof paint: This type of paint is available in two forms: one-component and two-component. Advantages of cement-based waterproof paint include high surface adhesion, water resistance, and long lifespan. However, its main drawback is poor resistance to vibration and shock due to its lack of elasticity.
Silicate-based penetrating waterproof paint: This type of paint offers numerous advantages, such as excellent adhesion, the ability to address internal leaks, high durability, and versatility in various waterproofing applications.
Bitum Polymer-based waterproof paint: This category includes two types: liquid waterproofing paint for creating a water-blocking membrane and torch-on membrane waterproofing. The benefits of Bitum Polymer-based waterproof paint include fast application and compatibility with various paint surfaces. However, its durability, lifespan, and membrane joints are generally inferior to those of other waterproofing types.
PU-Polyurethane-based waterproof paint: This is a two-component liquid waterproofing compound made from solvent-based plastic resin and offers multiple functionalities. PU-based waterproof paint exhibits exceptional adhesion, surface coverage, and elasticity, effectively sealing cracks and preventing leaks.
Classification by application location
Interior waterproof paint: This type of paint is specifically designed to optimize alkali and salt resistance, as well as water resistance for structures. Combining interior waterproof paint with exterior waterproofing provides comprehensive protection for the building against various water sources, minimizing cracking, paint peeling, and structural damage caused by moisture intrusion.
Exterior waterproof paint: This paint is applied to the exterior of buildings, serving both as a waterproofing barrier and an exterior decorative coating. Selecting the appropriate exterior waterproof paint is crucial for maintaining the aesthetic appeal and structural integrity of the building. Each waterproofing method has its own advantages and disadvantages.
The Most Effective Exterior Wall Waterproofing Paint Application Process
Preparation
Step 1: The first crucial step is to clean the wall to ensure it is clean, dry, and stable, ensuring a high degree of accuracy in the waterproofing process.
Step 2: Fix cracks, holes, and defects on the wall
This process helps to cover up cracks and breakage. You can use wall filler to seal these holes. This ensures both aesthetics, saves paint, and provides fast and effective waterproofing.
Waterproofing painting process for exterior walls
Step 1: Apply a layer of waterproofing paint to cover the entire surface of the wall that needs waterproofing.
Step 2: Let the wall surface dry completely for 4 hours.
Step 3: Apply the second coat of paint, completing the waterproofing painting process for exterior walls
Notes during construction
Color selection: Choose a white waterproof primer and apply it evenly with a moderate thickness.
Number of coats: If you apply 2 coats of primer, you only need to apply 1 coat of topcoat. If financially possible, you can apply a second coat to make the project more beautiful and waterproof, and last longer.
Time for waterproofing paint application: It is recommended to apply paint on dry, sunny days, during the dry season, to avoid wet weather affecting the quality of the paint.
Prioritize positive waterproofing: With the advantages of easy application and proactive protection, positive waterproofing is always the most optimal solution.
Choosing a waterproof paint: Prioritize using high-quality paints from reputable brands like Nippon Paint, which has been recognized by the market for its quality for a long time!
