Masticing in Bromley | Your Local Sealant Specialist

Why Mastic Fails – Insights from the Bromley Area’s Local Mastic Man

• Poor Adhesion – One of the primary reasons for masticing failures is poor adhesion. A professional mastic man, like ours in Bromley, will ensure that there is a clean, dry surface for proper adherence. However, if the surface isn't adequately prepared or if contaminants like dust and moisture are present during application, there may be a failure to bond, leading to the need for sealant repairs later down the line.

• Inadequate Flexibility – Masticing is expected to accommodate structural movements without losing its sealing properties. However, if the mastic lacks flexibility or if you apply it too thinly, it can't withstand the expansion and contraction of building materials. Consequently, it may crack or pull away from surfaces, compromising its effectiveness over time. That’s why we recommend Bromley residents bring in a sealant specialist to get the job done right the first time, saving you ££ on the mastic repairs that amend the issue.

• Exposure to UV Radiation – Masticing exposed to prolonged sunlight and UV radiation can degrade over time. UV rays break down the molecular structure of the mastic, causing it to become brittle and lose its elasticity. This degradation weakens the seal, making it susceptible to leaks and allowing water infiltration.

• Temperature Extremes – Extreme temperatures, both hot and cold, can impact the performance of masticing. In freezing conditions, mastic may become rigid and prone to cracking, while in high temperatures, it may soften and lose its adhesion properties. These temperature fluctuations can accelerate wear and tear, leading to premature failure of the sealant, and you needing to call in our Bromley mastic man for the requisite sealant repairs.

• Incorrect Application Techniques – Masticing requires precision and expertise. Incorrect application techniques, such as using the wrong tools or applying uneven pressure, can result in uneven coverage and weak spots in the seal. Additionally, failure to allow adequate curing time or improper mixing of components can compromise the integrity of the sealant. This is why, as a sealant specialist providing mastic repairs and installation services, we’re often demand amongst Bromley residents and companies.

• Age & Deterioration – Like any material, masticing has a finite lifespan, at which point sealant repairs will be required. Over time, exposure to environmental factors, moisture, and mechanical stress can cause it to deteriorate. As it ages, masticing may lose its flexibility, adhesion, and sealing properties, making it more prone to failure and requiring timely mastic repairs or replacement.
