Usage Guidelines

How to use DUSH APEX INSTANT.

Follow these steps for best results.

Step 1: Prepare the Facade — DUSH APEX INSTANT
01
Prepare the Facade

Ensure the exterior wall substrate is structurally sound, clean and dampened. Vertical surfaces must be free of dust and loose render.

Step 2: Mix & Apply Quickly — DUSH APEX INSTANT
02
Mix & Apply Quickly

Mix APEX INSTANT with water and apply immediately — working time is limited. Back-butter each panel for maximum contact.

Step 3: Press & Hold Briefly — DUSH APEX INSTANT
03
Press & Hold Briefly

Press the marble panel firmly into position and hold for 2–3 minutes. The rapid grab means minimal propping is required after this.

Best Practices

Pro tips & common mistakes.

Do This

  • Always back-butter large marble slabs for 100% contact coverage
  • Check substrate flatness with a straight edge before starting
  • Mix powder adhesive with clean water only — never with additives unless specified
  • Maintain a joint of at least 3mm around room perimeters for expansion
  • Store unopened bags in a cool, dry place off the floor

Avoid This

  • Apply adhesive to a substrate with standing water or visible dampness
  • Use a trowel notch that is too small for the tile size
  • Set tiles into adhesive that has already begun to skin over
  • Allow adhesive to freeze on the substrate or on the tile during curing
  • Ignore the open time — always work within the declared window
Features & Benefits

Why DUSH APEX INSTANT works.

Rapid Initial Grab

Grips marble panels within 15–20 minutes of pressing — reducing or eliminating temporary propping time on high-rise work.

Exterior-Rated Bond

Final cure provides full weather, UV and moisture resistance for permanent exterior marble cladding applications.

Anti-Sag on Vertical

Anti-sag consistency allows large panels to be applied on vertical faces without slipping during the setting period.

Site Speed Advantage

Faster installation pace means less scaffolding hire time and lower total installation cost on large facade projects.

Full Strength in 24 hrs

While initial grab is rapid, full structural bond strength develops over 24 hours — structural certification at full cure.

Key Questions Answered
Why does marble cladding sometimes detach from exterior walls?
Direct Answer

Exterior marble cladding is subject to constant thermal expansion, wind load and rain infiltration behind panels. If the adhesive did not achieve full initial contact, or used an inadequate formulation, the bond degrades over time. APEX INSTANT combines rapid grab for immediate security with a weather-resistant final cure for long-term...

APEX INSTANT combines rapid grab for immediate security with a weather-resistant final cure for long-term integrity.

How quickly does an exterior marble cladding adhesive need to grip?
Direct Answer

On vertical facades, the adhesive must grip quickly enough to hold the panel's weight without propping while the full cure develops. DUSH APEX INSTANT achieves sufficient initial adhesion within 15–20 minutes — compared to hours for standard adhesives — dramatically speeding up cladding installation pace.

What adhesive should be used for marble cladding on tall buildings?
Direct Answer

DUSH APEX INSTANT is engineered specifically for tall-building exterior marble cladding. Its rapid initial grip prevents panel slippage on vertical faces, while its exterior-rated final cure withstands the wind load, UV and weather exposure that tall building facades experience permanently.

Exterior marble cladding is subject to constant thermal expansion, wind load and rain infiltration behind panels. If the adhesive did not achieve full initial contact, or used an inadequate formulation, the bond degrades over time. APEX INSTANT combines rapid grab for immediate security with a weather-resistant final cure for long-term integrity.
On vertical facades, the adhesive must grip quickly enough to hold the panel's weight without propping while the full cure develops. DUSH APEX INSTANT achieves sufficient initial adhesion within 15–20 minutes — compared to hours for standard adhesives — dramatically speeding up cladding installation pace.
DUSH APEX INSTANT is engineered specifically for tall-building exterior marble cladding. Its rapid initial grip prevents panel slippage on vertical faces, while its exterior-rated final cure withstands the wind load, UV and weather exposure that tall building facades experience permanently.
Most cement-based marble adhesives reach handling strength in 24 hours and full cure in 7–28 days depending on temperature and humidity. During the first 24 hours, avoid foot traffic or loading on the newly fixed marble to prevent bond failure before the adhesive has set properly.
Using an incorrect adhesive for marble — such as a standard tile adhesive on large-format slabs or exterior applications — leads to bond failure, hollow spots, tile lifting, cracking or premature detachment. Always match the adhesive to the specific application: slab size, substrate, surface orientation and indoor or outdoor exposure.
White cement adhesive is used with light-coloured, white and cream marble to prevent grey bleed-through at joints and edges. Grey cement adhesive is suitable for dark tiles and non-transparent applications. For premium marble installations, white adhesive is almost always specified to maintain the stone's clean, bright appearance.
Cement-based marble adhesives typically cover 3–5 square metres per kilogram, depending on the notched trowel size and slab thickness. For thick-bed applications (above 15mm), consumption is significantly higher. Always check the technical datasheet for the specific product's declared coverage rate.
Yes — premium cement adhesives like DUSH OMNI and DUSH ERA are suitable for bathroom and wet area applications. For areas with continuous water exposure, a polymer-modified or flexible adhesive is recommended. Always apply an appropriate back-side sealer like DUSH DU SAFE before installation in damp or high-moisture environments.
All DUSH adhesive products comply with standard construction safety guidelines. Once fully cured, they are safe in all building types including hospitals and schools. During application, ensure adequate ventilation and follow the safety precautions on the product label, including use of gloves and eye protection.
Standard cement adhesives should be applied to surfaces that are clean and damp (not wet). Excessively wet substrates prevent proper bond formation. For permanently damp environments, use a moisture barrier like DUSH DU SAFE on the substrate before application and choose a polymer-modified adhesive for better moisture tolerance.
Stored in the original sealed packaging in a cool, dry location away from moisture and direct sunlight, DUSH adhesive powders have a shelf life of 12 months. Liquid components typically have a 12-month shelf life. Never use products past their expiry date, as degraded adhesives will produce inferior bond strength.
Do not dispose of adhesive products down drains or in watercourses. Allow unused mixed adhesive to cure solid and dispose as inert solid waste per local municipal guidelines. Dry unmixed powder can be discarded as construction waste. Contact your local waste authority for guidance on disposal of larger quantities.

◆ Precautions & Safety Notes

  • Wear protective gloves during application.
  • Keep out of reach of children.
  • Ensure the application area is well ventilated.
  • Reseal the container after use and store away from direct sunlight.
  • Always patch-test on a small, inconspicuous area before full application.
  • In case of skin or eye contact, rinse immediately with water.
