Is It Possible To Apply A Layer of Glass Glue Directly After Cracking? Don't Let 'easy' Become 'troublesome'!

Glass glue is a common material in home decoration and daily maintenance, widely used for sealing and bonding of doors, windows, countertops, sinks, and other parts. However, over time, many people will find that the glass glue has cracked.

Faced with this situation, many people try to save time by simply adding a layer of glass glue on top.

But is the fact really that simple? Today we will delve into this issue in depth.

PART-01

The hidden danger of directly repairing glue | It may seem effortless, but it's actually a hidden danger

1. The effect is greatly reduced: After the glass adhesive cracks, gaps have already appeared in the original sealing layer. Directly adding a layer of glass glue on top may seem to fill the surface gap, but in reality, it is difficult to form a tight and uniform bond between the new glass glue and the old cracked glass glue.

2. Appearance is affected: It is difficult to ensure that the color and texture of the new adhesive are completely consistent with the old adhesive when repairing the cracked glass adhesive. Even if the same brand and model of glass adhesive is used, there will still be significant differences in appearance between new and old adhesives due to differences in production batches, usage environments, and other factors.

3. There is a risk of secondary cracking: if the cause of glass glue cracking is not fundamentally solved by simply repairing the glue directly, the newly repaired glass glue is likely to crack again in subsequent use.

Correct handling method | Thoroughly clean and rebuild

1. Thoroughly clean old glue: To deal with cracked glass glue, you can use a professional glass glue remover to apply it to the old glue, wait for a period of time for the remover to fully penetrate and soften the old glue, and then carefully scrape off the old glue with tools such as scrapers and shovels.

2. Clean the construction surface: After cleaning the old adhesive, the construction surface should be cleaned. Use a clean cloth or sponge dipped in an appropriate amount of cleaning agent to thoroughly wipe off dust, oil stains, impurities, etc. on the construction surface. After cleaning, make sure the surface is dry, as damp surfaces can affect the adhesion and curing effect of the new adhesive.

3. Re glue construction: Re glue on a clean and dry construction surface. Choose glass adhesive with reliable quality and suitable for the usage environment, and operate it according to the requirements in the product manual. When applying glue, it should be uniform and continuous, ensuring that the thickness of the glue layer is moderate, without bubbles or gaps.

Preventing cracking | Starting from the source to extend service life

1. Choose high-quality glass glue: There are many types of glass glue on the market, and the quality varies greatly. When choosing glass adhesive, it is important to select products with reliable quality and excellent performance based on the usage environment and requirements.

For example, for damp environments such as kitchens and bathrooms, glass glue with good waterproof and anti mold properties should be selected; For parts such as doors and windows that require certain pressure and vibration, it is necessary to choose glass glue with good elasticity and strong adhesion.

2. Standardize construction technology: Construction technology has a crucial impact on the effectiveness and lifespan of glass adhesive. Before applying glue, ensure that the construction surface is clean, dry, smooth, and free of impurities such as oil stains and dust. During the curing process, avoid touching and moving the adhesive area to avoid affecting the curing effect.

3. Regular inspection and maintenance: Even if high-quality glass glue is used and standardized construction is carried out, it is necessary to regularly inspect and maintain the glass glue during use. Regularly check whether the glass adhesive has cracks, peeling, discoloration, etc. If any problems are found, they should be dealt with in a timely manner.

It is not a wise choice to directly apply a layer on top of the cracked glass adhesive. Although it may seem convenient, it can actually bring many problems such as poor sealing effect, affected aesthetics, and the risk of secondary cracking. The correct way to handle it is to thoroughly clean the old glue and carry out construction again.
