What is the construction thickness of cement based permeable crystalline waterproof coating?

Use a brush or roller to directly roll the treated base surface, and do not miss the brush. If there are pores when brushing, the gas should be discharged repeatedly and brushed repeatedly, and the first time after the coating, after the surface is not sticky, then staggered and brushed the second time, so repeated at least two to three times, and the thickness of each time does not exceed. That is, no more than three times, too thick and easy to crack.

If you want a more professional and good waterproof brand, we recommend you to choose Keshun waterproof.

Founded in 1996, after more than 20 years of steady operation and efficient development, Keshun Waterproof Technology Co., Ltd. has grown into a comprehensive building materials company with comprehensive waterproof solutions as its main business, integrating engineering building materials, civil building materials and building repair business sectors, and its business scope covers domestic and foreign countries.

Keshun Co., Ltd. in Guangdong Gaoming, Jiangsu Kunshan, Jiangsu Nantong, Liaoning Anshan, Shandong Dezhou, Chongqing Changshou, Shaanxi Weinan, Hubei Jingmen, Fujian Sanming layout of a total of 9 production and R & D bases, each base has the industry's advanced environmental protection treatment equipment, advanced imported production equipment, complete warehousing and logistics system, covering the national production strategy layout can provide customers with satisfactory products and services in a timely and efficient manner.

First of all, the surface of the waterproof base must be moist and flat, solid and clean, not too smooth, and rough is preferred. The water-cement ratio is strictly controlled during construction.

The mixed product should be used within 60 minutes, stirring frequently if it thickens. When squeegee rolling: powder:

Water = 1::035 weight ratio) When spraying: powder:

water = weight ratio). According to the different thickness requirements of the project and the construction method, the brushing method needs to be painted 2 3 times, the amount of each pass, the scraping method needs to be smeared 2 times, the amount of each time is about, and the dry sprinkling method is constructed, and the amount of each time is about. After completion, it is used for waterproof coating per 1mm thickness.

If you don't know what to say, you can consult the following**.

Hello dear I am glad to write you: how much is the general setting time of cement-based infiltration and crystalline waterproof coating? Penetrating waterproofing agents solidify in 10-15 minutes.

Under normal circumstances, 24 to 48 hours after the waterproof construction can be carried out by Qiao Yutaka to carry out the closed water test, if the waterproof material used is a rapid solidification waterproof coating, the closed water test can be carried out two to three hours after the waterproof construction. The time of the closed water test shall not be less than 24 hours, and if it is an outdoor roof waterproofing, the closed water test shall not be less than 48 hours.

Cement-based permeable crystalline waterproof coating is a very popular waterproof coating on the market, because its waterproof performance is very good, and the construction is convenient, plus the main component of this material is Portland cement and active compounds with this mixture, compared with other waterproof coatings on the market, its construction plan and characteristics are relatively special, what is the construction plan of using cement-based permeable crystalline waterproof coating? What is its scope?

1. First of all, we need to use clean water to wet the construction surface, and then keep the construction surface in a wet state, we can use cement-based permeable crystalline waterproof coating to carry out construction according to the method of spraying or brushing.

2. After the completion of the construction of the first waterproof coating in the first Sensen, use your fingers to gently press it to check the dryness of the waterproof coating, and then repeat the cement-based permeable crystalline waterproof coating after waiting for 4 or 5 hours, and control the grounding width of the waterproof layer as much as possible at about 10cm during construction.

2. Precautions for the construction of cement-based permeable crystalline waterproof coatings.

Before waterproofing the ground, it is necessary to do a good job of the base layer, and the temperature requirements of the cement-based permeable crystalline waterproof coating for the construction environment are also very high, if the temperature of the construction environment we are in is lower than 5, the uniformity of the construction of the waterproof coating will be affected to a certain extent.

In addition, within 48 hours after the completion of the waterproof project, we need to use clean water for maintenance, and the number of spraying water can not be less than about 4 times, this practice can effectively prevent the phenomenon of dry cracking of the waterproof base, especially for the hot summer, it is very necessary to do a good job of curing and curing, and only this practice can present a more perfect construction process.

Article summary: cement-based permeable crystalline waterproof coating is a relatively advanced way of material, the waterproof performance of this material is very obvious, and the requirements for the quality of the base layer are also very strict, so it will be more secure to hand over to professional masters to build.
