After the bathroom does the waterproof engineering test, is it necessary to make a concealed enginee

Try not to damage the original waterproof layer.

In the newly delivered building, the floors of toilets, bathrooms and kitchens are all waterproofed in accordance with the relevant specifications, and as long as the original waterproof layer is not damaged, there will generally be no leakage. But now the common problem is: the decoration will add some bathing facilities and a variety of water and water pipelines to rearrange or move, itself has destroyed the original waterproof layer, and did not repair or redo the waterproof construction in time, so it is very easy to leakage. >>>More

Of course, you can, generally do another layer of waterproofing on it, and then close the water for 48 hours to see if there is leakage downstairs, and you can put tiles if there is no leakage.

It is best to disassemble and re-do waterproofing, otherwise there will be endless troubles! If someone uses the method of brushing glue to remedy it, will it be non-toxic? (Or do partial waterproofing, make a small pool, or take a bath.) ）

1. The cost of all specific bathroom waterproofing depends on the waterproof scheme you choose and the waterproof material you choose. >>>More

Clean the base surface first, and then rinse it with water, the cleaner the base surface treatment, the better, after the base surface is done, then use the plugging king to plug the sewer pipe, floor drain pipe and other nozzles around the leakage treatment, if possible, then use polyurethane, or acrylic to paint the periphery of the nozzle, this process is done after drying. Then use cement mortar to level, the yin corner should be made into a garden corner, and after the leveling layer is dry, you can directly do waterproof construction. It should be noted when painting waterproof coatings, because most of the coatings are two-component, first mix the powder and liquid materials according to the proportion of the instructions for use, and then paint, first match half of the material, because do the brushing twice, the material should also be mixed twice, the mixed material should be used up at one time, it is strictly forbidden to add water to dilute it halfway, wait until the first time to dry and then paint the second time, the direction of the second brush should be perpendicular to the first time, so that the painting will be more even, will not miss the coating, and the waterproof on the wall should be meter high. This can prevent the tide from infiltrating into the next room, after the waterproofing is done, outsiders are prohibited from stepping on it, protect the waterproof layer, and pay attention to the protection of the waterproof layer when the next construction sequence, and if possible, you can also do a layer of cement mortar protective layer.
