Microcement Problems: The Most Common Issues and How to Avoid Them
Even with high-quality continuous coatings like Topciment microcement, challenges can arise. These issues often stem from ignoring basic application principles, leading to cracks, fissures, or crevices. Proper support repair, following the correct application steps, and hiring professionals are essential to avoid marks and stains. Let’s explore the common factors that can lead to subpar results in both new constructions and renovations.
W
hat is Microcement?
Microcement is a continuous decorative coating without expansion joints, making it resistant to cracking if applied correctly. It’s a thin layer, only 3 millimeters thick, which adapts well to horizontal and vertical surfaces due to its lightness, not adding significant structural load.
Technical and Constructive Qualities:
Durability: Resistant to abrasion, traffic, impacts, UV rays, water, humidity, and scratches.
Aesthetic Flexibility: Available in over 100 colors and various finishes, allowing for a wide range of decorative styles.
Microcement enhances spaces both indoors and outdoors by creating seamless surfaces that reflect light, which is beneficial in smaller rooms. It also insulates against moisture, cold, and heat.
Features of Microcement
Microcement has become popular due to its many benefits:
Resistance: Durable against moisture, temperature changes, impacts, dirt, and heavy traffic.
Flexibility: Can be applied over existing surfaces like tiles, plasterboard, marble, and plaster without extensive work.
Aesthetics: Provides a smooth, modern, and elegant finish, available in any color to suit various decorations.
Ease of Maintenance: Easy to clean and maintain with periodic sealing.
Cost-Effectiveness: While relatively economical, costs can vary based on area size, repair needs, applicator experience, and application difficulty.
Common Mistakes to A
void in Microcement Application
Adhering to the correct application phases ensures successful projects. Skipping steps can lead to significant issues. Here are key steps and common mistakes to avoid:
Applying Microcement at Incorrect Temperatures:
Ideal temperature: 15ºC to 25ºC.
Too cold delays curing; too hot causes premature hardening.
Improper Mixing of Microcement Pigment:
Incorrect mixing can cause lumps and dark streaks.
Ensure a homogeneous mixture for uniform color.
Ignoring Installation Steps:
Follow specific steps based on surface type (vertical or horizontal).
Properly condition and level the base to avoid future irregularities.
Correctly apply the primer and sealer for optimal protection.
Overlooking Moisture Issues:
Prime surfaces correctly to prevent moisture from causing damage.
Use appropriate primer products like Primapox® 100 Barrier to neutralize moisture.
Using Inadequate Sealers:
Choose the correct sealer for the specific type of microcement applied.
Incorrectly Repairing Microcement Areas:
Repair imperfections carefully to avoid noticeable contrasts.
Fissures and Cracks in Microcement
Despite its durability, microcement can develop cracks due to various reasons:
Low-Quality Microcement:
Use high-quality materials like Topciment to prevent cracking.
Expansion Joint Issues:
Respect existing expansion joints when applying microcement over materials like concrete slabs.
Poor Surface Conditions:
Repair the base surface adequately before applying microcement to prevent cracks.
Applying Over Parquet:
Avoid using microcement over parquet due to its moisture sensitivity and instability.
By adhering to these guidelines, modern craftsmen in the Byron Bay and Gold Coast areas can achieve flawless, durable, and aesthetically pleasing microcement finishes with Topciment. This ensures enhanced quality and longevity for any construction or renovation project.
