Bathroom waterproof how to do what materials need to use
The bathroom is the place with the most water in the home space, especially when bathing, basically the floor is full of water, once the waterproof measures are not done well, it is easy to leak to the downstairs, resulting in inconvenience of life, neighborhood disputes and so on. How does the bathroom waterproof ? What materials are needed? Let's take a look with Xiao Bian.
How to do a bathroom waterproof material
The choice of waterproof material has a great influence on the waterproof effect of the bathroom, so it is best to strictly check when selecting materials. This can also avoid the situation where workers buy fake materials to shoddy, or cut corners and the like. The waterproof material of the bathroom is recommended to use mortar waterproof agent, K11 waterproof coating, JS waterproof coating and polyurethane waterproof coating.
How to do toilet waterproof II. Construction steps
1, brush the first time waterproof coating
Make sure the ground is clean and dry before waterproof construction, and then paint more and more when the waterproof coating is applied. If you want to paint completely without any omission, check to see if it is firmly bonded to the grass roots, no cracks, no bubbles, no Such phenomena as shedding and the like require that the effect and thickness of the product must meet the product requirements.
2, brush the second time waterproof coating
When brushing the second pass of waterproof coating, it must be spaced from the first pass. Wait until the first pass of the paint is dry before applying the second pass. Look specifically at the dry condition of the paint. If the interval is too short, the paint should be If it does not dry out, its waterproof effect will be greatly reduced.
3, shop protection layer
After the waterproof coating is applied, a protective layer is laid on the surface. This is to prevent other constructions from damaging the waterproof layer. This protective layer requires complete coverage of the waterproof layer, no omission, solid bonding with the grass roots, no cracks, no bubbles, no Shedding phenomenon and so on.
4, closed water test
Finally, a water-retention test is also required. The water at the highest point of the ground must not be lower than 2 cm. Then it must be stored for at least 24 hours. After observing no leakage, the waterproof work is completed; if there is leakage, it must be reworked. Row.
How to do bathroom waterproof
1. Make sure the floor of the bathroom is stable
Before the bathroom floor is waterproof, be sure to first ensure the flatness of the ground, you can first level, and then do a waterproof treatment, so as to avoid leakage due to uneven thickness of the waterproof coating.
2, seams to brush in place
When applying waterproof paint, pay attention to the seams between the bathroom wall and the seam between the upper and lower water pipes and the ground. These locations are the most prone to problems.
3, wall treatment is also very important
In the bathroom waterproofing treatment, not only the ground should be waterproof, but also the wall should be waterproof around 30 cm high. This is to prevent the accumulation of water through the wall, and the non-load-bearing light wall is full of the entire wall. Apply waterproof coating only.
4, keep the water open
While waterproofing, pay attention to all sewers, including floor drains, plumbing fixtures, etc., and keep them open.
Editor's Note: The above is about how the bathroom waterproof and waterproof materials need to be introduced, the bathroom's waterproof work must be done well.

Description about Coronavirus(COVID-19)test Test
The Coronavirus(COVID-19)test is a solid phase immunochromatographic assay used in the rapid, qualitative and differential detection of IgG and IgM antibodies to the 2019 novel coronavirus in human whole blood, serum or plasma. The Coronavirus(COVID-19)test is intended for professionals within highly complex settings and or pharmacies. The test delivers rapid results between 2 and 10 minutes from individuals having signs and symptoms of SARS-CoV-2 infection
What conditions to do the Coronavirus(COVID-19)test?
1.Breating difficulty
2.skin sores, which may become a skin ulcer that heals very slowly
3.stuffy nose, runny nose, and nosebledds.
4.swallowing difficulty
TEST OVERVIEW for the Coronavirus(COVID-19)test
- Utilizes human whole blood, serum, or plasma
- Used in rapid, qualitative and differential detection of IgG and IgM antibodies
- Delivers clinical results between 2 and 10 minutes at the point-of-care
- Visual interpretation of results
- No special equipment needed
PERFORMANCE CHARACTERISTICS
The COVID-19 lgG/lgM Rapid Test (Whole Blood/Serum/Plasma) has been evaluated with the 126 samples obtained from patients exhibiting pneumonia or respiratory symptoms. The results were compared to Fluorescent Real Time Polymerase Chain Reaction (RT-PCR) or clinical diagnosis (including chest Computed Tomography and clinical signs etc.) of [Diagnosis and treatment of novel coronavirus pneumonia."
IgG/IgM Rapid Test results compared to SARS-CoV-2 RT-PCR results:
COVID-19 RT-PCR Assay | Coronavirus(COVID-19)test | ||
Positive | Negative | Total | |
Positive | 103 | 9 | 112 |
Negative | 0 | 14 | 14 |
Total | 103 | 23 | 126 |
95% CI | |||
Sensitivity | 103/112 | 91.9% | (85.3% – 96.3%) |
Specificity | 14/14 | 100% | (76.8% – 100%) |
Overall | 117/126 | 92.8% | (86.9% – 96.7%) |
The sensitivity of lgM only test is 89.2% (100/112) and specificity is 100% (14/14).
The sensitivity of lgG & IgM test is 91.9% (103/112) and specificity is 100% (14/14).
RT-PCR Method testing was included as clinical site method. Nucleic acid was detected by probe fluorescence PCR. This product contained primers and probes (ORF1ab gene and N gene strains of coronavirus) and internal controls (housekeeping gene beta Globin gene sequences) used in RT-PCR for the in vitro qualitative detection of SARS-CoV-2 RNA in nasopharyngeal swab specimens. The novel coronavirus2019-ncov specific probe was respectively labeled with FAM fluorescence and ROX fluorescence, and the internal standard gene was labeled with VIC fluorescence. The minimum detection limit of the fluorescent RT-PCR assay is 10 copies/reaction.
LIMITATIONS
- Use fresh samples only.
- This test has not been reviewed by the FDA.
- Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus.
- Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals.
- Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.
- Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E. Some specimens containing unusually high titer of heterophile antibodies or rheumatoid factor may affect expected results.
- Not for the screening of donated blood
