How to patch the corners of stone splicing?

作者:


This is because if the joint is cut into sharp corners, the stone is prone to edge collapse. A broken edge board may be scrapped. So. During factory processing, a minimum of 3-5mm will be left, while a maximum of 1cm will be left. And then they are spliced together, creating this "external corner".

1、 Treatment of external corners

Pay attention to the white patch line, which is the external corner. Why is it made into such a corner?

This is because if the joint is cut into sharp corners, the stone is prone to edge collapse. A broken edge board may be scrapped. So. During factory processing, a minimum of 3-5mm will be left, while a maximum of 1cm will be left. And then they are spliced together, creating this "external corner".

operation

1. Adhesive patch for small external corners

If the width is 3-5 mm, it is called a "small external corner".

When processing small external corners, adjust the marble glue to match the color of the stone, or use white marble glue directly on some stones. Use a screwdriver to scrape into the gap.

Next, there is an important step, which is to use a blade or shovel to scrape off the excess glue along the gap when the glue is half dry, leaving a complete and thin glue repair line. The remaining part is wiped clean with steel wool.

2. Glue repair for large external corners

If the width reaches more than 1cm, it is called a "big external corner". The glue filling method for large external corners is similar to that for small external corners. I won't repeat it here. But due to its large width, there is a problem with glossiness. There are two situations:

One way is that the factory has already polished this area before leaving the factory. After using a screwdriver or blade to treat the excess glue, if there are any traces of glue left, a small amount of VD stone oil and glue remover can be applied, and it can be cleaned by wiping with steel wool.

Another method is that if the factory does not perform polishing, a portable polishing machine and dry grinding discs can be used to grind 5-6 sizes, and finally, a 3000 # or 6000 # sponge can be used for polishing. There is no need to create crystal quality here, just create a soft and glossy effect.

2、 Treatment of internal corners

The "pressure angle" in the internal corner

When processing the internal corners, the adhesive is also adjusted and squeezed into the gaps for compaction. Then, when the glue is half dry, use a screwdriver (or softer material to prevent scratches) to scrape out the glue repair line. Finally, if there are adhesive marks left, spray VD stone degreaser and glue remover, and wipe with steel wool to remove them.

To avoid damaging the overall feel of the stone by adding glue like the one shown in the figure below.

3、 Other details processing

At the corners of walls, tabletops, and other places, there are also some details.

1. Joint pressing treatment

The "pressure joint" formed by the docking of plates also needs to be treated with glue filling.

And most of the time, the exposed side of the board is not polished. There is a clear contrast with the highlight area next to it. Therefore, in addition to adding glue, it is best to renovate and polish this area to achieve consistency with the surrounding environment.

Caulking

method:

Step 1: Use a portable polishing machine and dry grinding discs to grind a total of six sections from 0 # to 5 #.

Step 2: Mix VD marble gold powder, VD stone sealing glaze No.1, and VD stone sealing glaze No.2 evenly in a 1:1:1 ratio, and apply them to the area to be polished.

Step 3: Use a portable polishing machine and a 7-inch cleaning pad to evenly polish until the surface is smooth.

Step 4: Use a semi dry towel to clean the surface residue.

Difference in glossiness

2. Sharp angle processing

Another detail is to grind the sharp corners of the panels at the joint into oblique or circular arcs. This is because this sharp angle has a blade like feeling, which not only gives people a sense of insecurity visually, but also poses a certain degree of danger in fact.
