How to build a watertight fish pond? Do it yourself What is the ratio of sand to cement? What other materials need to be added to ensure water tightness?

If you want to build your own fish pond, you must be waterproof. As for the sand-cement ratio, it is 1:2. If you want to be waterproof, you don't need to add some materials. You need to make several waterproof layers to make it leak-proof. It's not as simple as you think. As I said, it won't leak.

The first step is to build a fish pond.

Just build by laying bricks or stones with cement mortar. At this time, the first protective water will be made, and waterproof powder will be added to the cement mortar at the ratio of 1:3, and the inside and outside of the pool will be leveled with cement mortar, and the thickness is preferably above 1CM.

Step 2: Brush waterproof paint.

Spread the waterproof material evenly on the fish pond, do not deposit locally, and brush it as many times as possible to make the bond stronger. But don't brush it very thick, otherwise it will be difficult to dry thoroughly and easy to delaminate. The thickness should be controlled at1mm. ..

Step three, brush the waterproof paint again.

The second time needs a certain time interval with one side, and the first time is dry before the second time can be brushed.

The fourth step is to stick bricks.

The tiles here are not just random tiles, but mosaic tiles for swimming pools to make the fish pond look better. It also has a certain waterproof effect.

Step 5, coat a layer of transparent waterproof paint.

Do you think it's over after you put up the bricks? You need to apply another layer of waterproof paint. Since we want to be waterproof, we want the best.

Here it is. I know that some people must say that I am wasting money and don't need so many layers of waterproofing, but if you are not waterproof well, the loss of water leakage will be much more than if I spend money on this waterproofing, just in case, it must be right. It is better to spend more money now than to catch up afterwards.
