SikaLatex Water Resistant Bonding Agent and Mortar Admixture

SikaLatex 20KG – Water-Resistant Bonding Agent and Mortar Admixture in Ghana

SikaLatex 20KG is a high-performance water-resistant bonding agent and mortar admixture used to improve adhesion, strength, flexibility, and durability of cement mortars, screeds, and plasters. It is specially suited for Ghana’s tropical climate and is available both online and in-store at CETECH Ghana for contractors, builders, and serious DIY users.

Formulated as a synthetic rubber emulsion by Sika, SikaLatex enhances bonding between new and old concrete, improves plaster performance, and supports long-lasting results in wet and humid environments such as bathrooms, kitchens, water tanks, and exterior walls.

What Is SikaLatex 20KG and What Does It Do

SikaLatex 20KG is a liquid synthetic rubber emulsion used in cement-based construction as:

• A bonding agent between old and new concrete
• A mortar admixture to improve cement mixes
• A plaster and render performance enhancer
• A water-resistant additive for screeds and repair mortars

Direct functional definition:

• It increases adhesion between cement mortar and substrate
• It improves water resistance of cement-based layers
• It enhances flexibility and reduces cracking risk

Material Composition and Technical Type

SikaLatex is technically classified as:

• Synthetic rubber emulsion
• Polymer bonding agent
• Cement mortar admixture
• Liquid bonding slurry component

Material behavior inside cement systems:

• Forms polymer-modified cement matrix
• Improves internal bonding structure
• Enhances flexural and tensile performance
• Reduces permeability

It is not a decorative coating. It is a functional construction chemical that upgrades cement-based materials.

How SikaLatex Improves Cement Mortars and Plasters

When used correctly, SikaLatex modifies mortar and plaster performance at multiple levels.

Adhesion improvement:

• Stronger bond to concrete substrates
• Better grip to masonry surfaces
• Improved tile bed and screed bonding

Mechanical performance:

• Higher flexural strength
• Better resistance to microcracking
• Improved abrasion resistance in screeds

Moisture behavior:

• Increased water resistance
• Reduced water absorption
• Better performance in damp zones

Workability enhancement:

• Smoother mortar handling
• Better trowel response
• Improved surface finish quality

Core Application Areas in Building and Construction

SikaLatex is perfect for use in:

Tiling and bonding old concrete to new concrete:

• Bond coats between hardened and fresh concrete
• Adhesion layers before new toppings

High-quality plastering and rendering mortars:

• Internal plaster improvement
• External render enhancement
• Decorative cement finishes

Floor screeds and patch repairs:

• Polymer-modified screeds
• Thin bonded toppings
• Repair patches

Repair mortars for damaged walls and surfaces:

• Spalled concrete repairs
• Surface restoration
• Edge and corner rebuilding

Waterproof screeds in bathrooms, kitchens, and water tanks:

• Wet room screeds
• Kitchen floor toppings
• Water-retaining structure screeds

Why SikaLatex Performs Well in Ghana’s Climate

Ghana’s climate presents specific construction challenges:

• High humidity
• Frequent rainfall
• Wet service areas
• Heat and moisture cycling

Standard mortar without polymer modification may:

• Debond from substrate
• Crack under stress
• Absorb excess moisture
• Fail prematurely in wet zones

SikaLatex addresses these risks by:

• Improving adhesion strength
• Increasing flexibility
• Enhancing water resistance
• Supporting long-term durability

This makes it especially suitable for tropical climate construction and renovation.

Correct Application Method and Best Practice Steps

For best bonding results, follow these site-proven steps.

Surface preparation:

1. Clean substrate thoroughly
2. Remove dust, grease, laitance, and loose particles
3. Ensure surface is structurally sound

Pre-wetting requirement:

4. Always apply on a pre-wetted surface
5. Surface should be damp but without standing water

Bond coat preparation:

6. Mix SikaLatex with cement to form a slurry
7. Stir until uniform

Application:

8. Apply slurry by brush
9. Maintain approximately 1–2 mm thickness
10. Apply substrate mortar immediately after

Critical timing rule:

• Do not allow bonding slurry to dry before placing mortar

CETECH Ghana provides product use consultations to help contractors and masons apply SikaLatex correctly on site.

Important Usage Notes and Safety Information

Mandatory usage notes:

• Always apply on a pre-wetted surface using a brush
• Mix as a slurry for best bonding effect before applying mortar
• Apply mortar immediately after slurry coat

Safety note provided by manufacturer guidance:

• May contain allergenic agents
• Read and follow manufacturer’s safety instructions before use

Site safety best practices:

• Use gloves during handling
• Avoid skin contact
• Avoid ingestion
• Keep container sealed when not in use
• Store away from extreme heat

Durability and Lifespan Benefits for Structures

Polymer-modified mortars made with SikaLatex show measurable durability improvements.

Durability gains include:

• Stronger substrate bond
• Reduced delamination risk
• Better crack resistance
• Improved impact tolerance
• Longer service life of repairs

In Ghana building environments, this translates to:

• Fewer repair cycles
• Longer-lasting plaster and screed work
• Better performance in wet rooms
• Reduced maintenance costs over time

Comparison With Standard Mortar Without Bonding Agent

Standard mortar only:

• Lower adhesion to old concrete
• Higher shrinkage cracking risk
• More brittle behavior
• Lower water resistance

Mortar with SikaLatex:

• High adhesion bond strength
• Improved flexibility
• Better water resistance
• Higher durability
• Better repair performance

For bonding new concrete to old concrete, a bonding agent like SikaLatex is considered best practice rather than optional.
