Waterproof coating

We all know that the balcony is the place with the most water in daily life, and the balcony waterproof project must be done well, otherwise it will affect the daily quality of life. So how to do the balcony waterproof project? The first thing to be clear is what kind of waterproof material is used to do the waterproof project, and the material selection is half of the success of the waterproof project.
Taking into account the characteristics of the balcony location, often use water, and belong to the indoor home environment, so in the selection of waterproof materials, the first consideration is the durable waterproof performance and safety of the material, here it is recommended to use polymer cement waterproof coating to do balcony waterproof project.

1. What are the advantages of polyurethane waterproof coating?

Polyurethane waterproof coating has a relatively high elongation strength, and this material has a high solid content, so it is relatively good bonding force, in addition, the polyurethane waterproof coating on the market is also divided into a single group and two groups, users can choose according to their own needs.
Polyurethane waterproof coating in the construction, as long as the base surface is treated well, it can naturally level, which also reduces the difficulty of construction, because of its high quality extensibility, it will also make the paint in the encounter of cracks, can be better effectively filled, to prevent leakage in the later stage, bringing some unnecessary troubles. So make sure you take care of it in advance.
The construction method of polyurethane is relatively simple, and it can be said that its environmental protection is relatively high, and it will not produce some toxic substances after construction, so it can be used normally indoors, of course, because of the weatherability of the paint is also better, so it can also be used in the outdoor environment.

2,Construction technology of polymer cement waterproof coating

Base surface treatment: use shovel, broom and other tools to remove construction waste, such as stains need to be cleaned with solvents, the base has defects or sand running phenomenon, need to be re-trimmed, Yin and Yang corner parts in the usual time to make a circular arc.
Coating primer: When the flatness of the base is poor, the appropriate amount of water is added to the modifier (the general proportion is the modifier: water =1: 4) After mixing evenly, apply on the base surface to make the base coating, stir with a blender until uniform and fine, the mixture without aggregates can be used, the number of ingredients according to the engineering surface and the labor arranged by the completion time, the prepared material should be used up within 40 minutes.
Large layer coating scraping polymer cement waterproof coating: divided vertical and horizontal direction scraping polymer cement waterproof coating, the latter coating should be in the previous coating surface dry but not dry construction (under normal circumstances, about 2 ~ 4 between the two layers).

3. Polymer cement waterproof coating construction precautions

1, Mixing is not uniform

The performance of polymer cement waterproof coating is directly related to the mixing uniformity of liquid and powder. Although the correct method of on-site mixing is specified in the manufacturer's instructions and packaging, in the actual operation process, many construction teams are perfunctory to the mixing process, and some even find a few sticks on the scene to manually stir a few times, so that the cured film performance is greatly reduced.

2. Add too much water

In order to improve the permeability of the paint to the base and improve the adhesion to the base, most manufacturers will recommend in the instructions for use that water beyond the specified amount of water can be added to dilute the paint during the first brush construction. Therefore, many people misunderstand that the polymer cement waterproof coating can be added water at will, and it is this operation that destroys the formula proportion of the waterproof coating, the formula of the product is optimized after several tests, balancing the mechanical properties and construction properties of the material, and arbitrarily changing the proportion of any one of the components has a great impact on the performance of the coating film.

3, Acceptance standards are not clear

The impermeability of polymer cement waterproof coating obviously depends on the change of material thickness, and there is a sudden change in a certain thickness range. With the increase of specimen thickness, the tensile strength decreases and the elongation increases. Therefore, taking the average thickness of the waterproof layer as the basis for the acceptance of waterproof engineering can avoid the influence of objective conditions and ensure the mechanical properties and waterproof effect of the waterproof layer.
