Good Practices

Marble is a porous metamorphic rock, which contributes to its beautiful appearance but also makes it susceptible to staining. Recognizing its porosity is important for taking preventive actions like sealing to protect it from potential damage due to liquid infiltration. Marble is also sensitive and vulnerable to acids, scratching and etching.

Material

• The type of materials used for the vanity top must be selected accordingly to the usage and environment in order to extend its life cycle and fulfil its aesthetic performance.
• Compressed marble may be preferred as they are relatively good substitution for stone finishes (Figure 1).
• Compressed marble is a densely mineral filled methyl methacrylate with the durability and rugged uniqueness of stone combined with the workability of hardwood. Due to its man-made characteristics, the design of the material is relatively flexible and its property could be varied as accordingly to suit the demand of the owners or the environment.
• The initial cost of compressed marble was much more economical than using stone finishes.
• In the long run, compressed marble would be a better choice as it could be cleaned and maintained easily.
• Planned maintenance programme is essential to maintain the appearance of the materials used. Quick response to the staining may reduce the seriousness of the defects.

Construction

The vanity top should be constructed with proper slope to fall to prevent water from ponding. One essential preventive measure is applying a high-quality sealer, which creates a barrier to stop liquids from penetrating the surface and causing stains. Use sealers specifically made for marble and adhere to the manufacturer’s application instructions. To ensure continuous protection, reseal the marble regularly, taking into account usage and environmental factors.
