SILKCOAT-13 is a synthetic polymer based thick colourless chemical compound which is an additive to any Water-based Primer Or Acrylic Paint, crack filling Powder and Cement Mortar. It is designed to improve the performance of cement-based wall putty, crack-filling, selected waterproofing applications and Cement mortar in bathroom sunken slab.

SILKCOAT-13 is primarily used to improve the cohesion adhesion, workability, bonding, Flexibility, Crack-filling performance, Water-resistance characteristics, better Surface finish and overall performance of cementitious wall-finishing materials. In short it increases the durability of the wall during interior and exterior wall painting.

1) During interior and exterior wall painting with any water-based Primer or acrylic Paint.
2) Water seepage over walls or wall dampness and ceiling in interior and exterior walls.
3) To fill the cracks in interior and exterior walls.
4) As a water proofing agent in bathroom sunken slab.
5) Repair and renovation works
6) Selected waterproofing applications

Usage of SILKCOAT-13 increases the durability of interior and exterior walls.
1) It make interior and exterior wall Water Proofing.
2) It renders 25 % to 40% Extra area coverage
3) It make smooth flow of brushes and rollers, thereby increasing the workability for the Painter
4) Reduces the maintenance cost of Brushes and Rollers
5) Get 20% saving in Painting cost

Common pathways include:
Rainwater → Exterior Wall → Pores / Capillaries / Hairline Cracks → Wall Interior → Dampness
Other sources may include:
1) Poor exterior wall protection
2) Cracks in plaster
3) Porous plaster
4) Defective joints
5) Plumbing leakage
6) Bathroom/wet-area leakage
7) Terrace or slab leakage
8) Rising dampness
The source of active leakage must always be identified and rectified first.

Water penetration through walls can result in:

1) Damp patches
2) Peeling or blistering paint
3) Paint discolouration
4) Fungal/algal growth
5) Efflorescence
6) Hairline cracks
7) Poor surface appearance
8) Progressive deterioration of the wall finish

Water can enter through surface pores, capillaries, hairline cracks and weak interfaces in cementitious wall finishes.

Reducing interconnected pore/capillary pathways
↓
Improving cohesion of the cementitious layer
↓
Improving substrate bonding
↓
Reducing water absorption and penetration
↓
Reducing the likelihood of surface dampness

This makes SILKCOAT-13 particularly relevant where water penetration is occurring through a porous or inadequately protected cementitious surface.

No. Structural cracks must first be investigated by a qualified engineer. SILKCOAT-13 should not be positioned as a substitute for structural crack repair systems.

For all type of issues, first we need to prepare the surface area before applying SILKCOAT-13 as a additive solution for all kinds of issues related to external & internal walls.

1.Preperation of Surface area:
The surface should generally be clean, free from dust and loose particles, free from oil and grease, free from loose paint or weak coatings, properly
repaired where necessary, and prepared according to the requirements of the selected application system.

During interior and exterior wall painting with any water based primer or paint:
a) Prepare the wall surface.
b) Dilute 1 Liter of SILKCOAT-13 first into the water that is required to dilute 10 or 20 Liters of Paint or Primer thoroughly.
c) Mix the solution prepared in step B into 10 or 20 Liters of Paint or Primer using a Stirrer thoroughly so that it gets uniformly mixed into the Primer
or Paint.
d) Apply the solution prepared in step C over the cleaned wall surface with 1 coat Primer & 2 coat Paint allowing sufficient time between each coating for
the wall to dry thoroughly.

During Crack Filling:
a) Prepare the wall surface.
b) Add required amount of SILKCOAT-13 to any crack filling powder thoroughly into a form of paste.
c) Widen the crack using the following tools triangular scraper or utility knife or joint rake.
d) Fill the paste prepared in step B into the cracks and plaster it.
e) Allow it to dry thoroughly.

During the application of Cement Mortar in Bathroom Sunken slab:
a) Before applying the cement mortar over the Bathroom Sunken slab, prepare the slab surface.
b) Apply directly SILKCOAT-13 horizontally over the slab one coat and vertically over the slab one coat allowing sufficient time between each coating for
the slab to dry thoroughly.
c) Mix 1 Liter of SILKCOAT-13 into the required quantity of water to make the cement mortar in the form of paste for applying over the slab
d) After applying the cement mortar, allow sufficient time to dry

1)Builders & Real Estate Developers:
They can use SILKCOAT-13 in wall-finishing systems for Apartments, Villas, Individual houses, Commercial buildings, Residential projects and Large-scale
developments.

2)Civil Contractors:
They can use for Wall putty, Crack-filling, Cementitious repair, Surface finishing, Selected waterproofing applications and during wall painting.

3)Painting Contractors & Applicators:
They can use during Interior and exterior wall painting.

4)Wall Putty Manufacturers:
Manufacturers can evaluate SILKCOAT-13 as an additive in their cement-based wall-putty formulations.
Better formulation performance → Better application → Better finish → Potentially improved paint coverage.

5)Waterproofing Contractors:
Waterproofing contractors can consider SILKCOAT-13 for compatible cementitious waterproofing formulations, particularly for wall and surface-treatment
applications.

However, it should be positioned as an additive within a properly designed waterproofing system, rather than as a standalone waterproofing product.

6)Architects & Architectural Consultants:
They can use during finishing stage of construction projects that delivers Longer-lasting wall finishes + better surface quality + moisture-resistance
support.

7)Civil Engineers & Site Engineers:
They can recommend SILKCOAT-13 when evaluating Wall putty systems, Crack repair, Dampness treatment, Cementitious coatings and Renovation systems.

8)Renovation & Building Repair Contractors:
They can use when they frequently encounter Damp walls → Cracks → Peeling paint → Poor adhesion → Repainting.

9)Building Material Dealers & Distributors:
Dealers can sell SILKCOAT-13 to Contractors, Painters, Applicators, Small builders and Renovation contractors.
Note: For this segment, the product needs a simple benefit-driven sales story rather than a highly technical explanation.

10)Professional Painters:
If painters see a practical benefit from SILKCOAT-13, they can recommend it to homeowners and contractors.

11)Individual Homeowners:
For homeowners, the product should preferably be sold through a trained applicator/contractor, because correct formulation and application are important.

10)Existing Apartment Building Association:
They can use it during their repainting of the existing apartment where they end up in saving huge money with longer wall durability.
