High-Performance Tile Adhesive for Internal Floors, Walls & Covered Balconies

Protector GTA Type-2 Grey Tile Adhesive from RVM DRY MIX™ is an advanced, polymer-modified cementitious adhesive developed for fixing ceramic and vitrified tiles on internal floors, walls, and covered balconies. It forms a high-strength, even adhesive bed that firmly locks tiles in place and withstands everyday movement, impact, and temperature changes in interior spaces.

Designed for thin-bed installations at a recommended thickness of 3–4 mm, GTA-2 improves surface levels while reducing adhesive consumption. Its smooth, creamy consistency offers excellent spreadability and non-slip characteristics, allowing precise tile placement on both floors and walls with adequate open time of 30 minutes and adjustment time of 30 minutes.

A single 30 kg bag of Protector GTA-2 covers approximately 70–80 SFT of tiling at 3–4 mm thickness, ensuring cost-effective tiling in living rooms, bedrooms, corridors, and semi-covered balcony areas. Manufactured under stringent quality standards and conforming to IS 15477:2019, EN12004, and ISO 13007:2017, GTA-2 delivers consistent performance, reliable bonding, and clean, long-lasting tile finishes for residential and commercial interiors.

Safety Directions

Usage Guidelines

Surface Preparation

  • Ensure substrates such as concrete floors, cement screeds, and plastered walls are structurally sound, clean, level, and fully cured.
  • Remove dust, laitance, loose particles, oil, paint, curing compounds, or any contamination that may affect adhesion.
  • Lightly dampen very dry, absorbent surfaces before applying adhesive, but avoid standing water or surface flooding.

Mixing Instructions

  • Pour approximately 4.8 – 5.2 litres of clean, potable water into a mixing container for each 30 kg bag of GTA-2.
  • Gradually add the powder to water and mix with a slow-speed mechanical stirrer (or manually) for about 3 minutes until a smooth, lump-free paste is obtained.
  • Allow the mix to stand for 2–3 minutes, then remix briefly before use to activate the polymers.
  • Use the prepared adhesive within its pot life of about 60 minutes. Do not add extra water once the mix begins to stiffen.

Application Guidelines

  • Spread the adhesive onto the substrate using a suitable notched trowel, maintaining a 3–4 mm bed thickness.
  • For better contact, use tile back-buttering where necessary, especially for larger tiles and balcony areas.
  • Press tiles firmly into the wet adhesive within the specified open time of 30 minutes, sliding slightly to ensure full contact and coverage.
  • Tap tiles gently with a rubber or wooden mallet to remove air pockets and achieve perfect alignment. Avoid traffic and grouting for at least 24 hours.

frequently asked questions

RVM Protector GTA-2 is a premium, polymer-modified grey tile adhesive formulated for fixing ceramic and vitrified tiles on internal floors, walls, and covered balconies. It offers strong adhesion, smooth workability, and durable performance in residential and commercial interiors.

GTA-2 is suitable for living room floors, bedroom floors, internal floors and walls, and covered balconies. It is designed for fixing ceramic tiles and vitrified tiles of small to medium size on sound, level cementitious substrates.

For a 30 kg bag of GTA-2, use approximately 4.8 – 5.2 litres of clean water. Add the powder gradually to water and mix to a smooth, creamy consistency suitable for application with a notched trowel.

Under normal site conditions, GTA-2 provides an open time of about 30 minutes, during which tiles should be placed onto the adhesive. After placement, tiles can typically be adjusted within 30 minutes to achieve correct alignment and level.

One 30 kg bag of GTA-2 covers approximately 70–80 sq.ft of tiling area at a bed thickness of 3–4 mm. Actual coverage may vary depending on tile size, substrate flatness, and trowel notch size.

Yes. GTA-2 is specifically recommended for covered balconies where the tiled surface is protected from direct, heavy rain. For fully exposed outdoor areas or permanently wet zones, consult RVM DRY MIX™ for specialised exterior-grade adhesives.

No. GTA-2 does not require external water curing under normal site conditions. Proper hydration occurs through its polymer-modified formulation when applied as recommended.

GTA-2 has a shelf life of 12 months from the date of manufacture when stored in a dry, covered, moisture-free area. Bags should be kept on pallets, away from direct ground contact and protected from rain or excessive humidity.

Avoid inhaling dust and prevent contact with skin or eyes. Always wear protective gloves, a dust mask, and safety goggles when mixing and applying the adhesive. If irritation occurs, wash with plenty of clean water and seek medical advice if required.
