How to use waterproof coatings? How to use waterproof coatings?

Procedure 1: Clean the base surface. 2. Brush the interface agent (primer). 3. Paint 2-3 lines, each of which should be painted horizontally and vertically. 4. It is best to apply another topcoat.

Now waterproof coatings are divided into film type, permeable type, etc., which are different for different substrates. There are quite a lot of waterproof coatings on the Internet, which can be shipped directly to the home, and can be constructed to solve the waterproof problem by yourself, for the cement layer, it is a waterproofing agent, black gold steel waterproof guard permeable type, the effect is quite good, you can go to understand, it is to penetrate into the inside of the substrate to seal the pores to achieve the substrate itself waterproof! waterproofing coatings, roofs, facades.

Fish ponds, etc. can be used!!

You can contact the merchant you bought the waterproof brand to ask for specific usage.

1. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproof materials and flexible JS waterproof materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

1. Clean the base surface and moisten it fully; Use a brush and scraper to evenly coat the stirred slurry on the treated substrate;

2. After brushing a layer, wait for it to dry slightly (just not sticky) and then brush the second layer, and after the waterproof layer is completely dry, you can directly paste the facing tiles with suitable tile adhesive; Dosage: The thickness of the brush is about 1mm.

3. Easy to operate, only need to stir on site to use;

4. It can be constructed on a wet base surface (but there can be no stagnant water);

5. It can resist high hydrostatic pressure, and the front and negative water surface are effectively waterproof;

6. It has a certain toughness, which can cover small cracks and resist slight vibration;

7. Good abrasion resistance, good adhesion, can be directly plastered, leveled and pasted with appropriate tile glue on the waterproof layer after drying.

Buy a roller, brush, clean the wall, first use the roller to dip the paint to brush the ceiling, and then around, from top to bottom, the brush is rolled, brush it, to avoid unevenness, and possible downflow. If you feel that the paint is thicker, you can add water, stir and dilute... That's right, it's adding water.

1. Requirements for the base surface before construction: it must be smooth, and there must be no defects such as holes and grooves.

2. Before construction, the wall and ground need to be sprinkled with water to remove the gas in the wall holes, so that the wall surface is denser and the surface is more permeable.

3. When the powder and liquid are stirred, it is necessary to use an electric drill, and stop for 3-5 minutes after stirring at a constant speed; If it is manual stirring, it needs to be stirred for about 10 minutes, and then left for 10 minutes before use.

4. When using, if there are bubbles in the slurry, the bubbles need to be brushed open, and there should be no bubbles.

5. Note: The first time you need to paint in one direction, and the second time you need to paint in the opposite direction.

6. The interval between the first and second brushing is best about 4-8 hours.

7. The façade is not easy to brush out the thickness, and it can be painted several times There will be left and right holes and seams when painting, so it is necessary to paint it again and again to increase its density and fill the void density.

8. It is better to do the closed water test after 2-3 days of construction, and it is better to do the cement curing cycle within 7 days, and more maintenance is required.

With the continuous improvement of everyone's living standards, many new products are constantly presented in people's sight. Waterproof coating is one of the new products, which can meet the waterproof needs of users, so it quickly gained a foothold in the market. So, how to use waterproof coatings?

What should I pay attention to when using waterproof coatings? Let's take you to find out.

Waterproofing coatings are used in the order of mixing, painting, curing, protecting and inspecting. The waterproof coating needs to be poured into a container for stirring before use, and it cannot be poured all at once, it should be stirred while pouring, and the stirring time is best mastered in 3 to 5 minutes, and then stirred until there is no powder ball, no particles can be used.

Precautions for the use of waterproof coatings.

1. Stir the paint thoroughly.

The waterproof coating must be fully stirred before use, first pour the liquid additive into a clean mixing container, and then slowly pour the paint while stirring according to the specified proportion, stirring fully for 3 to 5 minutes, to the extent that there is no powder ball and no particles, and it must be used up within the operation time. You can also use machinery to mix, generally 400 to 500 rpm is enough.

2. Treat the substrate.

Rollers or brushes can be used to evenly apply the mixed slurry to the treated substrate. In the process of painting, it is necessary to decide whether to paint 2 layers or more than 2 layers according to the use environment and performance requirements, the thickness of the waterproof layer of general engineering is 1mm, and the thickness of the underground engineering construction specification is long.

3. Do a good job in the second layer of waterproof coating.

After the first layer of waterproof coating is done, it is necessary to wait for it to be slightly dry and just non-sticky, and then carry out the second layer of painting, which generally takes 1 to 3 hours, but the specific situation still depends on the density of the base surface and the temperature at that time.

Article summary: The above is all about how to use waterproof coatings and what to pay attention to when using waterproof coatings, I hope it will be helpful to you. If you want to know more about it, please stay tuned to Qeeka Home.

1. Stir.

Pour the liquid material into the container first, and then slowly add the powder, and stir fully for 3-5 minutes until a uniform slurry without raw flour and particles is formed. (It is best to use a blender).

2. Brushing. Use a brush or roller brush to apply directly to the base surface, and the strength is used evenly, and the brush should not be missed; Generally, it needs to be brushed twice (according to the requirements of use), and the thickness of each brush should not exceed 1mm;

After the previous one is slightly dry, the next one is brushed (just non-sticky, generally at an interval of 1-2 hours), and the front and rear vertical cross brushing, the total thickness of the brush is generally 1-2mm; If the coating has already cured, moisten it with water first when applying another layer.

3. Maintenance. After 24 hours of application, it is recommended to cover the coating with a damp cloth or spray water to cure.

4. Protection. Before it is completely dry after construction, please take protection against trampling, rain, exposure to the sun, sharp damage, etc.

5. Inspection (closed water test).

Toilets, pools, etc., should be filled with water for 48 hours after the waterproof layer is dried (at least 24 hours in summer, at least 48 hours in winter) to check whether the waterproof construction is qualified. Lightweight walls must be tested for watering.

Although waterproofing coatings are more commonly used, it is also necessary to understand the specific operation methods. How to use waterproof coating? PChouse will take you to find out.

1. Waterproof layer base (leveling layer): the surface of the base layer should be solid with a certain strength, clean and clean, no floating soil, sand particles and other dirt on the surface, the surface is smooth, smooth, no loosening, and it is required to smooth and calender, and the residual mortar blocks or protrusions should be flattened with a shovel.

2. Stirring: first pour the liquid material into the container, then add the powder according to the proportion, and use the stirrer to stir fully for 3-5 minutes until a uniform slurry without raw flour balls and particles is formed.

3. Brushing: Brush directly on the base surface with a brush or roller brush, and the strength should be used evenly, and the brush should not be missed; Generally, it needs to be painted 2-3 times (according to the requirements of use), and the thickness of each painting should not exceed 1mm; After the first one is slightly dry, the next brush (non-sticky, generally 1-2 hours apart), the front and back vertical cross brushing, the total thickness of the brush is generally 1-2mm.

4. Maintenance: After 24 hours of construction, it is recommended to cover the coating with a damp cloth or spray water to maintain the coating.

5. Protection: Before it is completely dry after construction, please take protection such as prohibition of trampling, rain, exposure to the sun, and sharp damage.

Inspection (closed water test): toilets, pools and other parts should be filled with water for 48 hours after the waterproof layer is dried (at least 24 hours in summer and at least 48 hours in winter) to check whether the waterproof construction is qualified. Lightweight walls must be tested for watering.

Thank you! I can give you some advice on how to use waterproofing coatings. In my personal experience, I used to use waterproofing paint to protect the façade of my house. Here are some of the advice I've shared based on my own experience::

1.Preparation: Before application, make sure that the surface to be applied is clean and dry, free of oil or dust. You can use a brush or detergent to clean the surface to ensure that the paint adheres firmly.

2.Choose the right paint: There are a variety of different types of waterproofing coatings available on the market, so choose the right type of paint for your needs.

For example, some paints are suitable for interior walls, while others are suitable for outdoor use. You can consult with a professional to make sure you have chosen the most suitable paint.

Typically, you'll need to stir the paint to make sure the ingredients are evenly mixed. You can then use tools such as brushes, rollers, or spray guns to evenly apply the paint to the surface.

4.Multi-layer application: For better waterproofing, it is recommended to apply in multiple layers. After the first coat of paint is completely dry, the second coat is applied. This increases the thickness of the coating and improves the waterproofing performance.

5.Pay attention to the construction environment: During the construction process, pay attention to the temperature and humidity of the environment. In general, it is best to apply in dry and warm weather conditions, which will help the coating to cure and adhere better.

The above are some of my insights and experience sharing when using waterproof coatings. Hope it helps! If you have any further questions, please feel free to ask.

Waterproofing coating is a kind of coating that can form a waterproof layer on the surface of a building, and is often used for waterproofing treatment of buildings such as roofs, walls, and basements. So, how do we make the waterproof coating for the bridge?

1.Preparation: Clean the work area and remove loose paint, dust and other dirt.

2.Stirring the paint: Stir the paint well to ensure that the colors and ingredients in it are mixed evenly.

3.Pre-treatment of the base layer: If there are cracks or holes in the base layer, it needs to be filled first. Use caulk or mortar to fill cracks and holes and make sure the fill is sufficiently dry.

4.Brush waterproof coating: Make the jujube evenly apply the waterproof paint to the construction area with a special brush or roller to ensure that each part is covered. More than two coats of painting are usually required to achieve the best results.

5.After completion: After the first coat is dry, the second coat is applied. After completion, the construction tools should be cleaned in time, and attention should be paid to keeping the construction area ventilated so that the paint can be fully dried.

Note: Different types of waterproof coatings have different usage methods and construction requirements, and you need to read the product manual carefully before use. At the same time, it is also necessary to pay attention to safety during the construction process, avoid contact with the paint and eyes, and clean it in time if there is an accident.

The use of waterproof coatings is usually as follows:

Preparation tools: including brushes, rollers, rollers, and thinners, etc.

Clean the surface: Remove dust, oil and loose paint from the wall or roof surface to ensure that the surface is dry and tidy.

Stir the coating: Stir the waterproof paint thoroughly. If a diluent is required, it should be added to the container according to the proportions in the paint instructions.

Start applying: Use an appropriate brush or roller to start applying. Start by tackling details that are more difficult to apply, such as corners and protrusions.

Reapply: After the first coat has dried, reapply the surface to increase the waterproofing effect.

Drying group letter in the time collapse: according to the thickness of the paint and temperature and other factors, so that the paint drying time is sufficient.

Aftercare: After the treatment is completed, please clean the brushes and other tools in time.

There are the following recommendations for the use of waterproof coatings:

1.Material storage. After purchasing waterproof paint, please store it in a cool, dry place away from high comic temperature and light. Check the shelf life of the product with the manufacturer before use.

2.Surface preparation. The surface should be clean, tidy and dry. If there are pre-packaged materials such as stucco and mortar, they should be completely cured and dried. Treat non-smooth surfaces with sandpaper to improve the adhesion of waterproof coatings.

3.Timing of airing. Wood coating should choose the time when the weather is dark and the wet slag finger is low. For example, to paint exterior masonry surfaces, you can choose early morning or late afternoon in summer.

4.Contact type. There are two types of waterproof coatings: waterborne and solvent-based. Solvent-based adhesive has strong strength, but it is volatile and toxic; The water-based waterproof content is easy to clean and relatively environmentally friendly.

5.Apply multiple times. Generally, 2-3 coats are required. Each application is spaced about 1 hour apart, and the direction of application is perpendicular to each other. The last one is a little thicker.

6.Post-maintenance. After the waterproof coating has been completely dried for about 2 weeks, you can consider applying another coat of paint to improve the waterproof effect.

7.Precautions. The waterproof coating has a certain impact on high temperature, sun exposure and long-term wear, and the coating should be updated in time due to regular maintenance.

Hopefully, the above usage methods will help you make the right use of waterproofing coatings. If there are still others.
