How to make a balcony fish pond waterproof

The waterproof material of the fish pond should be non-toxic, environmentally friendly and odorless, and it can adapt to the small construction area of the pool. Among the waterproofing materials, polymer cement-based waterproofing slurry (general-purpose waterproofing slurry, flexible waterproofing slurry) is the preferred material for waterproofing of fish ponds.

1. Comparison and selection of waterproof materials for fish ponds.

1) Compared with waterproof materials such as polyurethane and waterproofing membrane, polymer cement-based is cost-effective;

2) Polymer cement-based waterproof coating, environmentally friendly, non-toxic and harmless, will not pollute the water source, there will be no problem in raising goldfish in it, and will not produce irritating and harmful gases like polyurethane, which is the latest domestic household environmental protection waterproof coating;

3) The construction of polymer cement-based waterproof coating is relatively simple, and there is no problem for experienced waterproof masters as long as they are constructed in accordance with product requirements;

4) Polymer cement-based coatings contain both organic polymer emulsion and inorganic cement, which combine the two to make the combination of organic and inorganic, complement each other's advantages, combine rigidity and flexibility, improve impermeability, improve compression ratio, long durability, superior comprehensive performance, and achieve better waterproof effect.

2. Professional construction of waterproofing of fish ponds.

Please have a professional construction team to carry out the construction, and pay attention to the following matters during construction:

1) Base surface treatment is the foundation.

Base surface treatment is the key to waterproof construction, the base surface must be cleaned before construction to ensure that it is firm, smooth, clean, free of dust, greasy, wax, release agent and other debris substances, if there are pores, cracks and other defects, must be repaired and smoothed with cement mortar in advance, and the yin and yang corners should be wiped into an arc. Keep the base moist when there is no open water.

2) The brushing method should pay attention to the uniform strength of a single brush, and be careful not to miss the brush; Maintain a vertical intersection angle when applying the front and back two coats to fully cover the place; A single brush should not be too thick to prevent cracks after drying.

3) Conservation and protection are also important.

After 24 hours of construction, it is recommended to cover the coating with a damp cloth or spray water to maintain the coating, and it is forbidden to step on, rain, expose to the sun, and sharp damage before it is completely dry.

4) Carefully check to prevent future problems.

Be careful when brushing, and carefully inspect after painting, especially at the seams, yin and yang angles, nozzles and other parts; After the construction is completed, the closed water test should be done for 48 hours, and the closed water height should be increased as much as possible, not less than 20cm, and carefully check whether the water level has dropped and whether there is leakage.

5) Paint the protective layer of cement mortar.

The fish pond is waterproof, it is not recommended to use waterproof membrane, because the pool will have yin and yang angles, outlets and other places, the use of waterproof membrane is not easy to cut and paste, and the construction technical requirements for workers are relatively high, if the construction is not standard, it is likely to affect the final waterproof effect. Moreover, the waterproofing membrane will have a certain pungent odor relatively speaking, which is not environmentally friendly enough and may affect the water quality and the growth of fish.

Therefore, if it is an indoor fish pond, it is recommended to use mortar waterproofing agent directly, which is not only firmly bonded with the base surface, but also puncture-resistant, high strength, and the waterproof life can be the same as the life of the building.

If it is an open-air fish pond, then it is necessary to take into account that the sun and rain can easily lead to changes in the base surface of the structure, resulting in cracking. Therefore, it is necessary to combine rigid waterproofing + flexible waterproofing construction, that is, first paint the flexible type of K11 waterproof slurry, and then make a protective layer of mortar waterproofing agent to meet the needs of waterproofing.

Allowed, the load-bearing design of the balcony will not give you the kind of load-bearing that you are designed to have a bath.

Because of long-term immersion in water, polyurethane is the most scientific.
