The closing treatment of elevator door covers and stone walls can be carried out through the following methods:

抽縫填充：使用與石材顏色相近的填縫劑，將電梯門套與石材墻面之間的縫隙填滿。先清理縫隙，確保干凈無塵，然后使用填縫劑填充縫隙，將表面平整。

Joint filling: Use a joint filling agent similar in color to the stone to fill the gap between the elevator door cover and the stone wall. First clean the gaps to ensure they are clean and dust-free, and then fill the gaps with sealant to make the surface flat.

安裝金屬收口條：選擇合適的金屬收口條，將其安裝在電梯門套和石材墻面交接處。金屬收口條能夠有效地隱藏縫隙，增加美觀性，并且具有一定的保護(hù)作用。

Install metal closing strip: Select a suitable metal closing strip and install it at the intersection of the elevator door cover and the stone wall. Metal closure strips can effectively hide gaps, increase aesthetics, and have a certain protective effect.

使用密封膠：在電梯門套和石材墻面之間涂抹密封膠。密封膠能夠填充縫隙并形成密封層，具有一定的防水和防塵功能。

Use sealant: Apply sealant between the elevator door cover and the stone wall. Sealant can fill gaps and form a sealing layer, with certain waterproof and dustproof functions.

在進(jìn)行收口處理之前，確保表面清潔，并根據(jù)實(shí)際情況選擇更適合的方法。如果不確定如何處理，建議咨詢的裝修師傅或咨詢相關(guān)領(lǐng)域的人士。

Before performing the closing treatment, ensure that the surface is clean and choose the most suitable method based on the actual situation. If unsure how to handle it, it is recommended to consult a professional decorator or a professional in the relevant field.
