Winter is indeed coming faster. As soon as the Beginning of Winter is over, the temperature drops dramatically, the cold wind blows unceremoniously, the sky is gloomy, and occasionally there is sporadic light rain. This atmosphere makes people feel the coming of winter and makes people feel chilled.
In the face of low temperature attack, we humans are afraid of cold, and so are waterproof materials. Substantial cooling has a great impact on waterproofing construction, especially outdoor operations. So, what are the precautions for winter construction of waterproof coatings? Dezny Chemical offers you the following suggestions.
Waterproof materials have undergone strict low-temperature performance testing. As long as they do not freeze during transportation and storage, the quality will not be affected.
Next, Dezny will introduce to you the precautions for winter construction of waterproof coatings.
In the cold winter, product preservation is particularly important. Dry powder products are easy to absorb moisture, and the emulsion part of waterproof products is easy to freeze and freeze at low temperatures. Therefore, to ensure that the product survives the winter safely, you can pay attention to the following points:
1. Place the product in a warm and dry place. There should be no water accumulation or leakage in the warehouse. If conditions permit, it is best to moisture-proof the warehouse.
- For particularly cold areas, such as warehouse basements, etc., heating and insulation can be carried out appropriately. In other areas, sponges, straw and other materials can be used to cover or isolate products for insulation.
2. Waterproof construction in winter requires thin brushing
In addition to necessary dust removal and repair, the waterproof base surface must also be carefully inspected for structural defects. For problems such as honeycombs, holes, cracks on the base surface, and around upper and lower water pipes, you can use a slurry mixed with leak-proofing materials (such as Jinxing leak-proofing spirit) to fill and smooth them. Sharp edges and protrusions should be removed. For loose and porous base surfaces, waterproof paint should be used for smoothing and scraping. For nodes such as yin and yang angles, arc angles can be made.
Construction method: First, apply partial painting in the order from top to bottom and from left to right. Make sure the coating thickness matches the recommended application dosage. The purpose of applying thin brushes during winter construction is to prevent the paint layer from being too thick, which may cause the paint layer to dry unevenly and cause cracking. In addition, be careful not to make the slurry too thin or stir unevenly to avoid powdering or crusting.
3. Reduce the amount of wet water
When the base surface is too dry or has low evaporation, an appropriate amount of wet water is required when applying water-based waterproof coatings. However, when the temperature is low in winter, the evaporation of the base surface is not large, so the amount of wet water will be different compared with that in summer. In order to prevent the waterproof coating from taking too long to dry, the amount of wet water can be appropriately reduced to keep the base surface clear of water. During winter construction, you can wet one section and paint one section.
Summarize:
During winter waterproof coating construction, attention needs to be paid to product preservation, thin brush construction, reducing the amount of wet water, and the use of waterproof mortar. These considerations can help ensure the quality and effectiveness of waterproofing construction. However, special attention should be paid to the fact that the above suggestions are for reference only, and the specific construction must be carried out according to the actual situation and product description.
