The wall under the window oozes water.

Water seepage under the windowsill needs waterproof coating.

First of all, we should carefully check the cause of water leakage on the windowsill. If the window sill leaks because the leaking hole is blocked, we need to clean the leaking hole in time, which can help the window sill drain water. If there are cracks in the leaking part of the window sill, it means that the waterproof coating of the window sill has been damaged. At this time, it is necessary to repaint the waterproof paint, wait for it to dry naturally, and then reinforce the leaking part of the windowsill with cement. Finally, we can choose to use lime or tiles.
