How to measure the threshold stone size?
The size of the threshold stone in the bathroom and kitchen should be measured first, and there is no need to leave a ruler, because it should be pressed to the end when making the frame, and the width of the threshold stone should be calculated according to the big head. Generally, there will be a phenomenon of big head and small head at the door. The actual size should be about 3 cm, because the frame should be considered, and it is best to drink the outer frame and the lintel together. Secondly, we should consider the ground elevation difference between the bathroom and the corridor. If the height difference is less than 2 cm, there is no need to add sticky edges on one or both sides. Finally, consider the edge of the threshold, and consider 3*3, 5*5 or 20*5 according to the actual situation. But the key point is to do protective treatment, and it is six-sided protection.
The size, length and width of the threshold stone in the living room and bedroom are the same as the actual width of the doorway, and the width of the threshold stone should be the same as the thickness of the doorway wall. Pay attention to the thickness of the threshold stone in the bedroom, which should be the thickness of the door cover MINUS the thickness of a door [4CM], so that the wooden floor of the bedroom is paved and the bridge is installed directly below the door.
When measuring the size of the door opening, the height of the door (door frame) should be deducted from the height of the threshold stone, otherwise the later installation will be troublesome, and it is difficult to cut the stone along the door frame, and the effect is not good.
