5 Common Mistakes with Porphyry
5 Common Mistakes with Porphyry
Porphyry is tough and low-maintenance, but certain errors can still affect its appearance and longevity.
Mistake #1
Neglecting joint sand maintenance
Why this is a problem
Porphyry itself is non-porous and durable, but the joints can erode if not maintained. This erosion can lead to loose stones and weed growth, compromising the stability of the installation.
How to fix it
Replenish joint sand regularly and compact it to ensure stability. Use a polymeric sand for better binding properties.
Prevention
Inspect and refill joint sand annually, especially after harsh weather conditions. Use a high-quality polymeric sand to prevent erosion.
Mistake #2
Ignoring algae and moss buildup
Why this is a problem
Porphyry surfaces can become slippery and stained due to algae and moss, which thrive in damp conditions. This biological growth doesn't harm the stone but can make surfaces unsafe and unsightly.
How to fix it
Apply Lithofin Algex to affected areas and scrub with a brush to remove algae and moss.
Prevention
Treat porphyry surfaces annually with Lithofin Algex to prevent algae and moss growth.
Mistake #3
Using harsh chemical cleaners
Why this is a problem
Though porphyry is chemically resistant, harsh chemicals can damage joint materials and surrounding vegetation. This can lead to joint degradation and environmental harm.
How to fix it
Switch to Lithofin MN Outdoor-Cleaner for routine cleaning, which is effective yet gentle on the environment.
Prevention
Use Lithofin MN Outdoor-Cleaner regularly to maintain porphyry surfaces without harming the joints or environment.
Mistake #4
Pressure washing too frequently
Why this is a problem
Excessive pressure washing can erode joint sand and cause surface roughness over time. This mechanical action can weaken the structural integrity of the installation.
How to fix it
Limit pressure washing to once or twice a year and use a moderate setting to avoid damage.
Prevention
Combine pressure washing with Lithofin MN Outdoor-Cleaner to reduce the need for frequent high-pressure cleaning.
Mistake #5
Not addressing efflorescence on new installations
Why this is a problem
Efflorescence is a natural occurrence where salts migrate to the surface, appearing as a white powder. It can be unsightly but doesn't damage the stone.
How to fix it
Brush off efflorescence with a stiff broom or rinse with water. It typically disappears naturally over time.
Prevention
Ensure proper drainage during installation to minimize efflorescence. If persistent, clean with Lithofin MN Power-Clean.
