Is the water retaining strip installed before or after the tiles? When should the water retaining strip be completed?

We all know that many people will separate the wet and dry areas when decorating their bathrooms, and water barriers are usually installed for dry and wet separation. The installation of water barriers requires certain skills and particularities, especially the choice of time. So should water barriers be installed before or after tiling? Let's take a closer look!

Should I make the water barrier first or lay the tiles first?

Generally, before waterproofing the bathroom, install the water retaining strip, and then do the waterproofing when doing the waterproofing, and do the water-tightness test to check whether the water retaining strip is leaking. This water retaining strip is fixed on the ground with cement mortar. Because the bathroom floor originally has a waterproof layer, it is waterproofed once and twice, so that both sides of the water retaining strip can also be waterproofed, and the water blocking effect is better.

Another way is to install water retaining strips when laying tiles. This method is also acceptable. The inside of the water retaining strips also needs to be waterproofed. This is mainly to prevent the water retaining strips from leaking to the outside.

Of course, there are also water retaining strips installed after the tiles are laid, but the effect of this method is not very good. There is a gap between the water retaining strip and the tiles, which can only be sealed with glue. It is easy to age and debond over time, and it is easy to mold. However, this method is more flexible, that is, the water retaining strip can be removed at any time without affecting the decoration of the original floor.

If you are making a permanent water barrier, or installing a water barrier for a shower room, it is recommended to install it before laying the tiles. The effect of installing during the laying of tiles is similar to that of installing before laying the tiles, but it is better to install it first. The above two types of water barriers are embedded in the ground, which will be more secure. If installed on the tiles later, they are not as secure as the previous two types, and are surface mounted.

Advantages and disadvantages of installing the water retaining strip first and then

Install water retaining strips before laying bricks

In fact, the main difference between the two is that the water retaining strips are usually embedded in the floor tiles before paving. I think the advantage of this approach is that it is very durable. Because the pre-embedded part is underground, it is very strong. However, the gaps must be waterproofed. If the water retaining strip is broken, it will be inconvenient to remove it.

Install water retaining strips after paving

After the tiles are laid, the water retaining strip is mainly installed by sticking it on and applying glue. The advantage of this is that it is easy to remove, but if it is stuck to the tiles for a long time, the glued area is prone to mold and the water retaining strip may fall off.

What materials are the water retaining strips made of?

1. Marble water retaining strips, which are slightly more expensive, have decent color choices, and can be processed into the desired small size. It is the choice of many people for water retaining strips when decorating their bathrooms.

2. Resin water retaining strips can imitate marble effects. They are relatively cheap and are widely used by the public. They come in many colors and patterns, but their sizes are relatively large, usually more than 5 cm wide, which is relatively wide and not good-looking.

3. Granite water retaining strip, but this is not widely used nowadays.

If the water retaining strip is straight, I suggest not to make it too wide. You can make it 1.8 cm high and 2-3 cm wide. It will not look good if it is too high or too wide.
