The bathroom tiles have just been sprayed with waterproofing agent, and there are white crystals on

It is the gap part of the tile, as long as the waterproofing agent penetrates into it, you can use a cloth when wiping. Just don't hurt the gaps. Because the leaking part is not a tile, the white crystals that dry off without a problem are mainly methyl silicate.

1. The white crystals on the tile can be scraped with a shovel, or washed with oxalic acid or hydrochloric acid, but note that oxalic acid has a great smell and should be washed with a lot of light water. Hydrochloric acid will burn your hands, so it is recommended to ask a professional to clean it.

Second, the tiles at home have been used for a long time, and there will be stains that are difficult to remove, which can be cleaned in different ways according to the different degrees of stains

1. If it is stained with soy sauce, vinegar, etc., you can use toilet cleaner.

2. Stains such as tea, ice cream, and beer can be removed with soda ash solutions such as sodium hydroxide or potassium bicarbonate.

3. If it is stained with rust stains, you can squeeze the juice of fresh lemon on the rust stains and rub them repeatedly, and then wash them with soapy water. If you don't have fresh lemons, you can also use vitamin C tablets instead.

4. If the ink penetrates, try using toothpaste.

Generally yes, its active ingredients have penetrated under the tile, and there will definitely be crystallization on the surface. You also need to intermittently sprinkle water for maintenance several times to get better results.

I've also patched it with water repellent and it's ok.

It doesn't matter, it won't affect the waterproofing effect.

The ceramic tiles of the regular manufacturers themselves are waterproof, why do you have to do this more.

The white crystals after drying are mainly methicilicate, and there is no problem to wipe them off. Because the leaking part is not a tile, but a tile gap, as long as the waterproofing agent penetrates into it, you can use a cloth when wiping. Just don't hurt the gaps.

Whether you wipe it or not, it is difficult to achieve the waterproof and leak-proof effect that users expect.

At present, there is no mature waterproof product in the world that can penetrate into the crystal of ceramic tile to block moisture. At present, this kind of waterproof products that appear in China and are said to have infiltration function and play a waterproof role are basically conceptual products. Please choose carefully!

It can't be rubbed, you have to wait for it to completely penetrate into the brick, and wait for it to dry naturally, in order to achieve the waterproof effect.

That's a natural reaction to the waterproof liquid in the early stage!
