Sika Top Seal 107: Uses, Benefits & Waterproofing Guide

Waterproofing plays an important role in protecting concrete and masonry structures from moisture, seepage, dampness, and water-related deterioration. Among the commonly used cementitious waterproofing solutions, Sika Top Seal 107 is a two-component polymer-modified cementitious waterproofing system designed for concrete and mortar surfaces.

It combines a liquid acrylic polymer with a cement-based powder containing selected aggregates and special additives. Once mixed and applied correctly, it forms a protective coating that helps reduce water penetration while providing good adhesion to prepared substrates. Sika’s product information lists applications ranging from terraces and basements to water tanks, wet areas, roofs, retaining walls, and other concrete structures.

What Is Sika Top Seal 107?

Sika Top Seal 107 is a two-part acrylic polymer-modified cementitious waterproofing coating. The system consists of a liquid polymer component and a cement-based component. Unlike conventional waterproofing methods that may require complicated mixing, the product comes in pre-batched components designed for consistent preparation.

The coating can be applied using a brush, spray, or flat trowel depending on the application and required consistency. It can also bond well to damp, properly prepared substrates, making it suitable for many repair and waterproofing situations.

Satiate Solutions also describes SikaTop Seal 107 as a waterproofing coating used for applications including toilets, sunken slabs, flat roofs, terraces, basements, water tanks, retaining walls, and other structures.

Key Uses of Sika Top Seal 107

One of the major advantages of Sika Top Seal 107 is its versatility. It can be used for both interior and exterior waterproofing and damp-proofing of concrete, cementitious renderings, brickwork, and blockwork.

1. Terrace and Roof Waterproofing

Terraces, balconies, sunshades, and flat or small roofs are regularly exposed to rainwater and moisture. A properly applied cementitious waterproofing coating can help reduce water infiltration and protect the underlying concrete.

2. Basement and Retaining Walls

Basement walls are particularly vulnerable to dampness and water ingress. Sika Top Seal 107 can be used for internal and external waterproofing of suitable basement and retaining-wall surfaces.

3. Water Tanks and Reservoirs

The product is also specified for waterproofing potable water tanks, reservoirs, wastewater tanks, and other water-containing structures. Sika Top Seal 107 Seal IN is approved for potable-water contact.

4. Bathrooms and Wet Areas

Bathrooms, kitchens, utility areas, toilets, and sunken slabs are common areas where moisture can penetrate construction materials. Sika Top Seal 107 can provide a protective waterproofing layer when applied according to the relevant application requirements.

5. Swimming Pools, Gutters and Drains

The product is also listed for applications such as swimming pools, fountains, water bodies, RCC gutters, drains, planter boxes, lift pits, and sumps.

6. Hairline Crack Sealing

Sika Top Seal 107 can help seal fine hairline cracks in concrete where the cracks are not subject to movement. It should not be considered a solution for active or structurally significant cracks, which require appropriate assessment and repair.

Benefits of Sika Top Seal 107

Excellent Adhesion

A major benefit is its ability to adhere to properly prepared concrete, mortar, masonry, and other suitable cementitious substrates. Good adhesion helps the coating remain securely bonded to the surface.

Water Resistance

The coating helps prevent water penetration and improve the watertightness of suitable concrete and masonry structures. This makes it useful for areas exposed to moisture and water infiltration.

Easy Application

Sika Top Seal 107 can be applied by brush or thin trowel, with some product variants also allowing spray application. Its pre-batched components make mixing simpler and help provide consistent proportions during preparation.

Suitable for Damp Substrates

According to Sika’s Indian product information, the system bonds well to damp substrates. However, proper surface preparation remains essential for achieving reliable waterproofing performance.

Protection of Concrete

Beyond waterproofing, the coating helps protect concrete against water penetration, chloride penetration, and carbonation. Sika also lists resistance to abrasion and protection against certain environmental effects among the product characteristics.

Suitable for Interior and Exterior Applications

The product can be used for both internal and external waterproofing applications, making it suitable for residential, commercial, and infrastructure-related construction work.

How to Apply Sika Top Seal 107

Correct surface preparation is one of the most important factors in any waterproofing project.

First, the surface should be sound, clean, and free from grease, oil, dust, loose particles, and other contaminants. Satiate Solution recommends that concrete, mortar, and other applicable surfaces be properly cleaned before application. Absorbent surfaces should be thoroughly saturated with water before application, while avoiding standing water.

The two components should then be mixed according to the manufacturer's instructions. Because the product is supplied as pre-batched components, additional water should not be added unless specifically instructed by the applicable product documentation.

The prepared material can be applied using a brush, spray, or suitable trowel method. Depending on the project, multiple coats may be required. The coating should be allowed to cure as specified in the product documentation before the surface is exposed to water, traffic, or subsequent finishes.

For critical waterproofing applications, professional application and adherence to the latest technical data sheet are recommended.

Surface Preparation: Why It Matters

Even a high-quality waterproofing material cannot compensate for poor surface preparation. Before applying Sika Top Seal 107, cracks, damaged concrete, weak areas, laitance, and other surface defects should be appropriately treated.

The substrate should have sufficient strength and should be free of contaminants that could interfere with adhesion. Proper preparation helps the waterproofing coating form a continuous protective layer and improves the overall durability of the system.

Sika Top Seal 107 Packaging

The Indian product information identifies SikaTop-107 Seal IN as a pre-batched 25 kg set, consisting of a 5 kg liquid component and a 20 kg cement-based powder component. The product is supplied in grey mixed form, while the individual components have different appearances.

Satiate Solutions also lists packaging options for smaller and larger systems and provides product information for customers looking for Sika Top Seal 107 waterproofing solutions.

Why Choose Sika Top Seal 107 for Waterproofing?

Choosing a waterproofing system depends on the surface, water exposure, structural conditions, and project requirements. Sika Top Seal 107 offers a practical cementitious coating solution for many concrete and masonry applications.

Its combination of polymer modification, cement-based formulation, adhesion, water resistance, ease of application, and versatility makes it suitable for a wide range of waterproofing requirements. It can be particularly useful when a coating needs to be applied to properly prepared concrete or masonry surfaces in residential, commercial, and infrastructure projects.

However, waterproofing performance depends not only on the product but also on correct surface preparation, detailing, application thickness, curing, drainage, and treatment of joints and cracks.
