Large Format Grey Tile Adhesive for High Foot & Internal Vibration-Prone Areas

Protector GTA Type-3 Large Grey Tile Adhesive from RVM DRY MIX™ is a high-performance, polymer-modified cementitious adhesive engineered for fixing large ceramic tiles, vitrified tiles, marble stone, and granite on living rooms, bathrooms, kitchens, walls, and high foot & internal vibration-prone areas. It develops a strong, flexible bond that helps tiles withstand frequent movement and impact in demanding interior zones.

Formulated for thin-bed installation at a recommended thickness of 3–4 mm, GTA-3 ensures better level control while optimising adhesive consumption. The creamy, workable consistency spreads smoothly with a notched trowel and provides dependable non-slip behaviour, with an open time of about 40 minutes and tile adjustability window of 40 minutes for accurate alignment.

Safety Directions

Usage Guidelines

Surface Preparation

  • Ensure concrete floors, cement screeds, and plastered walls are sound, clean, level, and fully cured before tiling.
  • Remove dust, laitance, loose particles, oil, paint, curing compounds, and any material that may impair adhesion.
  • Lightly dampen very dry or highly absorbent substrates; do not leave standing water on the surface before applying adhesive.

Mixing Instructions

  • Measure approximately 4.8–5.2 L of clean, potable water for each 20 kg bag of GTA-3.
  • Slowly add the powder to water and mix using a slow-speed mechanical stirrer (or by hand) for about 3 minutes until a smooth, lump-free paste is achieved.
  • Allow the mix to rest for 2–3 minutes, then remix briefly before application to improve workability and bond.
  • Use the prepared adhesive within its approximate 60-minute pot life. Do not retemper or add extra water once the mix starts to stiffen.

Application Guidelines

  • Spread the adhesive with a suitable notched trowel to achieve a uniform 3–4 mm bed thickness on the substrate.
  • For large tiles, use tile back-buttering to ensure full contact and better stress distribution, especially in high foot and internal vibration-prone areas.
  • Place tiles into the wet adhesive within the 40-minute open time, slide slightly to ensure full coverage, and align properly.
  • Tap tiles gently using a rubber or wooden mallet to remove trapped air and achieve a flat, even surface. Avoid traffic and grouting for at least 24 hours under normal conditions.

frequently asked questions

RVM Protector GTA-3 is a polymer-modified large grey tiles adhesive designed for fixing large ceramic tiles, vitrified tiles, marble stone, and granite on internal living rooms, bathrooms, kitchens, internal walls, and high foot & internal vibration-prone areas. It delivers strong bonding, smooth workability, and durable performance in demanding interior zones.

As per the bag, GTA-3 is recommended for Living Room, Bathroom, Kitchen, Walls, and high foot & internal vibration-prone areas. It is suitable wherever a strong bond is needed for large-format ceramic tiles, vitrified tiles, marble stone, and granite on sound, level cementitious substrates.

GTA-3 is formulated to fix large ceramic tiles, vitrified tiles, marble stone, and granite as specified on the product bag. It is especially suitable for larger tile formats where higher bonding reliability is required.

As printed on the product bag, 20 kg of tiles adhesive will cover approximately 45–55 SFT of tiles at a bed thickness of 3–4 mm. Actual coverage may vary depending on tile size, surface flatness, and trowel notch.

The bag instructions recommend using about 4.8–5.2 L of clean water for each 20 kg bag. Add powder to water and mix until you obtain a smooth, lump-free, easily trowellable paste.

According to the product data on the bag, GTA-3 offers an open time of 40 minutes and an adjustable time of 40 minutes. Tiles should be laid within this window and can be repositioned during this period for accurate alignment.

S1 deformability indicates enhanced flexibility, helping the adhesive accommodate minor substrate movement and vibration while maintaining tile adhesion.

Under normal temperature and substrate conditions, tiles fixed with GTA-3 can usually be grouted and subjected to light foot traffic after about 24 hours. Heavier loads or cooler, very humid conditions may require a longer waiting period.

The bag states that the product may cause skin irritation and eye damage. It advises avoiding eye and skin contact, not breathing dust, and washing hands thoroughly after handling. If irritation occurs, wash with plenty of water and seek medical attention if needed.
