What is the ratio of sand to cement when laying floor tiles?

Calculate how much it will cost to decorate your home.

Cement mortar for paving floor tiles, as its name implies, is a mixture of cement and sand with water. In order to successfully complete the laying of floor tiles, the cement-sand ratio of floor tiles is very important, so let's first understand the cement-sand ratio of lower floor tiles and the matters needing attention when laying floor tiles together.

What is the ratio of cement to sand in floor tiles?

1. The proportion of cement and sand in floor tiles seems to be a problem left over from history, and there has never been an accurate data. Theoretically, the ratio of cement to sand in floor tiles is very simple, but there are no specific figures. Because the base surface is sometimes different, the cement sand used will be different.

2. For example, the mortar for large floor tiles needs to be thicker and easier to spread, so more mortar is needed. Generally, the normal thickness is 30-40mm, the minimum thickness is not less than 25mm, and the optimal operating thickness is 40mm. The same is true for small floor tiles. Although the area is small, it can be thick, but of course it can't be too thin. According to the empirical calculation method, the sand is calculated by 40× the thickness of the ground area first, and the cement is calculated by 0.2 generation per level. If it's not enough, make it up later.

What should I pay attention to when laying floor tiles?

1. Paving method: The wall tiles should be paved from bottom to top, with a gap of 1-3mm, and the gap should be leveled before pasting. The bonding material should be applied in the middle slightly higher than the periphery, and then fixed with a rubber hammer. At the same time, horizontal testing is needed.

2. The ground should be leveled: before construction, because some floors will be uneven, it should be leveled before laying a tile, so that the effect of ordinary tiles will be smoother. Or you can use dark tiles to frame the surroundings, and the tiles in the frame should be lighter. Of course, the floors of the kitchen and bathroom must be tilted, so as to facilitate drainage.

3. Treatment of waterproof layer: Before laying ceramic tiles, the last thing to pay attention to is the treatment of waterproof layer, especially in the kitchen and bathroom. If the tiles are replaced again, the previous waterproof layer of cement mortar will be destroyed. Therefore, it is recommended to lay a layer of asphalt waterproof layer before tiling, that is, cracks will appear between tiles, and it is best to fill them with white cement.

Summary: So, the above contents about the cement-sand ratio of floor tiles and the matters needing attention in construction are introduced here. Through the above introduction, I believe everyone knows the proportion of cement mortar and how to do better when laying floor tiles. Of course, although you don't need to do it yourself, you can also get a proper understanding of whether the decoration master is doing well.
