Description: AT-RAINSHIELDis an elastomeric waterproof, antifungal, odour-free coating that provides a tough,smooth and excellent crack bridging ability that can accommodate movements& other harmful effects due to thermal& seasonal variations.

STANDARDS:  AT-RAINSHIELDconforms toASTM D 412 : 2002, ASTM D 4541 : 2002, ASTM C 836: 1995, DIN 1048 Part 5&  ASTM D471


  • Building Roofs / Terraces.
  • Concrete screeds, acrylic coatings, sound brick-bat coba, lime terracing etc.
  • All types of exterior masonry surfaces, concrete, cement sand renderings, etc.


  • Waterproofing– Provides excellent water resistant coating on roof / terrace & exterior wall, increasingdurability of the structure.
  • Tough and abrasion resistant– Suitable for light foot traffic
  • Highly durable, light weight, UV resistant. Mechanical protection like screed concrete/cement mortar is not required. Provides long timeprotection to buildings endangered due to thermal degradation.
  • Elasticity & Flexible – Accommodates movement in waterproofing system, covers and bridges hairline cracks
  • Easy to apply– No need to remove the existing system but need to apply on sound surface. Can be applied by roller or brush on vertical surfaceswithout sagging.
  • High elasticity,withstands stress caused by thermal expansion & contraction.
  • Eco friendly– Non Toxic water based system
  • Durability– Provides long time protection to buildings endangered due to rain &thermal degradation


Surface Preparation – Roof

  • Prepare the concrete mother surface thoroughly by cleaning, washing and removing dust, dirt, oil, grease and loose particles by means of wire brush or any other mechanical methods.
  • In existing old terraces such as brick-bat-coba or screeds, the substrate must be checked for its soundness.Damaged or hollow portions, sharp edges, etc. must be cut and repaired with a polymer-modified mortar using AT-CRETE LATEX.
  • All surface cracks up to 5 mm width should be filled up.
  • Bitumen based waterproofing treatments must be completely removed by mechanical scarification or by any other suitable mechanical means.

Surface Preparations – Exterior Surface

  • All new cement-sand renderings/Plaster /concrete surfaces should be allowed to age 4 to 5 weeks before surfacecoatings.
  • Surface for treatment must be thoroughly cleaned of all laitance, loose material, oil, grease, etc. by mechanicalmeans such as wire brushing & shot blasting. Finally vacuum cleaning of all loose solids and liquids can be done,if required.
  • All surface cracks up to 5 mm width should be filled up.

Cracks more than 5 mm and all separation gaps should be filled up with AT-CRETE LATEX modified mortar

Application Procedure for Roof (New & Repair):

  • Apply one coat of AT-RAINSHIELD (diluted with water in the ratio 2 : 1) at the rate of 7 to 9 sqm./ Kg.Allow it to dry for 2-3 hours.
  • Apply the first coatAT-RAINSHIELD at the rate of 2 to 2.2 sqmt / Kg / coat and allow it to dry beforetaking up the second coat, the rate of application being the same. This would ensure correct consumption ofmaterial that will deliver a total DFT of 500 – 600 micron.
  • Minimum drying time between coats will be 4 to 6 hours.
  • Allow the system to air cure for 7 days minimum.
  • For Additional protection use Fibre mesh (minimum 40 gsm) after 1st coat of undilutedAT-RAINSHIELDforadditional re-enforcement or apply 3rd coat of undiluted AT-RAINSHIELD.

Application Procedure for Exterior Surface (New Construction):

  • Apply one coat ofAT-RAINSHIELD (diluted with water in the ratio 2 : 1) at the rate of 7.5 to 9 sqmtr / ltr.Allow it to dry for 2-3 hours.
  • Apply 1 coat of AT-RAINSHIELD (Diluted 1 ltr with water upto 5%) and apply at the rate of 3.7 to 4 sqm /ltr. / per coat. DFT: 110- 115 microns
  • Post application of single coat of AT-RAINSHIELD, apply suitable exterior paint as per desired colour.
  • If external surface is required in white colour, apply 2 coats of AT-RAINSHIELD (Diluted 1 ltr with water upto10%) apply at the rate of 3.1 to 3.5 sqmtr per Kg. / 2 coats. DFT: 120- 125 microns.

Application Procedure for Exterior Surface (Repair/Repainting):

  • Apply 1 coat of AT-RAINSHIELD (Diluted 1 ltr with water upto 5%) and apply at the rate of 3.7 to 4 sqm /ltr / per coat. DFT – 110 – 115 microns.

Precautions & Limitations: Roof

  • All corners, gaps, joints, protrusions & outlets shall be coated with extra coat
  • Do not apply during rains.
  • Substrate MUST be in SSD condition for application of primer coat.
  • The product is designed only for foot traffic and not meant for vehicular traffic. Not suitable for any machineryor equipment movement.
  • To achieve the comprehensive waterproofing, all parapet walls should be covered with AT-RAINSHIELD
  • All wall to floor joints must be provided with proper angle fillets prepared with polymer modified mortar using AT-CRETE LATEX.

Precautions & Limitations: Exterior Surface.

  • Dilute as per recommendation.
  • Apply as per recommended sqmtr area by forced coverage.
  • Ensure proper surface preparation.
  • Diluted material to be consume on the same day.



  • Clean all tools and equipments immediately after use with water.


  • Self-priming: Coverage 7.5-9 sqm per ltr / per coat. (Dilution 50%).
  • 2 coats for Roof – Coverage 2 to 2.2 Sqmtr / ltr / per coat (No Dilution).
  • Single coat Exterior Surface – Coverage 3.7 to 4 sqmtr / ltr / Per coat (Dilution 5%).
  • Two coat Exterior Surface – Coverage 3.1 to 3.5 sqmtr per ltr / 2 coats (Dilution 10%).

*Coverage can vary depending on the porosity of the surface.
