What Are Waterproofing Chemicals?

Waterproofing chemicals are specialised construction products used to reduce water penetration and protect building surfaces from moisture-related damage. Depending on their formulation, they may be applied as coatings, mixed into cement-based materials, or used as primers and bonding agents within a suitable waterproofing system.

These products are commonly used in new construction, renovation, concrete repair, and building maintenance.

Waterproofing chemicals may be used for:

• Roofs and terraces
• Bathrooms and shower areas
• Balconies and exterior walls
• Concrete surfaces and cementitious substrates
• Water-retaining structures, where the product is suitable
• Damp-prone construction areas
• Certain concrete repair and protective applications

The correct product depends on the type of surface, water exposure, movement or cracking, and the manufacturer's application recommendations.

Why Is Waterproofing Important for Buildings?

Waterproofing is an essential part of building protection. Rainwater, plumbing leaks, moisture migration, and water accumulation can contribute to damage if the affected areas are not properly treated.

Here are some important reasons to choose an appropriate waterproofing system.

1. Helps Prevent Water Leakage

A correctly selected and applied waterproofing system helps limit water penetration through suitable building surfaces. It can be particularly important for terraces, bathrooms, balconies, and other moisture-exposed areas.

2. Protects Walls and Ceilings

Water seepage may cause damp patches, paint blistering, peeling finishes, and staining. Appropriate waterproofing helps protect surfaces when the underlying cause of moisture has been correctly identified and treated.

3. Supports Concrete Durability

Water entering concrete can contribute to deterioration under certain conditions. Suitable protective systems can help reduce water ingress and protect concrete surfaces.

4. Reduces Maintenance Requirements

Addressing waterproofing problems correctly can help reduce repeated repairs and the costs associated with damaged finishes.

5. Helps Maintain Property Value

A well-maintained building with properly designed waterproofing systems is better positioned to avoid recurring moisture-related issues.

However, waterproofing chemicals are not interchangeable. The product must be suitable for the specific application, and structural cracks, plumbing leaks, drainage issues, or other underlying causes may require separate repairs.

Different Types of Waterproofing Chemicals

Before choosing a waterproofing product, it is helpful to understand the main categories and their uses.

1. Cementitious Waterproofing Chemicals

Cementitious waterproofing products are generally based on cement and selected additives, sometimes combined with polymers to improve their properties.

Depending on the formulation, they may be suitable for concrete and masonry surfaces, bathrooms, balconies, and other approved applications.

When selecting a cementitious waterproofing product, consider the substrate, moisture exposure, required flexibility, and whether tiles or other finishes will be installed over the treated surface.

2. Acrylic Waterproofing Coatings

Acrylic waterproofing coatings are commonly used for suitable exterior surfaces and exposed areas, depending on the formulation.

Certain products are designed to form flexible protective films that help resist water penetration and weather exposure.

Before purchasing an acrylic coating, check whether it is intended for the particular surface, exposure conditions, and expected movement.

3. SBR Waterproofing Admixtures

Styrene-butadiene rubber (SBR) latex products are commonly used as bonding agents and admixtures in cement-based mortars, screeds, concrete repair materials, and certain waterproofing applications.

When used according to the manufacturer's instructions, a suitable SBR product can help improve adhesion and modify the properties of cement-based mixes.

Saint Globle's SG SBR is described as a latex-based waterproofing and bonding admixture for applications including concrete repair, bonding of screeds and renders, and waterproofing-related work.

The correct mixing ratio and application method should always be taken from the current product documentation.

4. Waterproof Primers

A waterproofing primer or compatible surface primer may be used as part of a waterproofing system to prepare a substrate before subsequent treatment.

The purpose of a primer depends on its formulation. It may help improve adhesion or prepare an appropriate surface for a coating or other construction material.

Before using a primer, confirm its compatibility with the substrate and the waterproofing product that will be applied over it.

5. Flexible Waterproofing Coatings

Flexible waterproofing coatings are designed for applications where the product needs to form a continuous protective layer and accommodate movement within the limits of its specified performance.

These coatings may be suitable for certain terraces, balconies, bathrooms, and concrete surfaces.

For example, Saint Globle SG Globastic is described as a two-component, flexible polymer-modified cementitious waterproof coating for approved applications such as concrete surfaces, balconies, terraces, bathrooms, and swimming pools.

Always follow the product's instructions regarding surface preparation, application thickness, curing, and compatibility with subsequent finishes.

How to Choose the Right Waterproofing Chemicals

Choosing the right waterproofing chemicals requires an understanding of the surface, the source of moisture, and the conditions in which the product will be used.

Consider these important factors before purchasing.

1. Identify the Source of Water Leakage

The first step is to understand why water is entering the building.

Common causes include:

• Cracks in concrete or plaster
• Damaged terrace waterproofing
• Failed bathroom waterproofing
• Poor drainage or water accumulation
• Defective plumbing connections
• Gaps around joints and service penetrations
• Moisture rising through walls from the ground

The correct treatment depends on the cause. For example, a surface coating may not solve a leaking pipe, and a crack filler alone may not resolve a structural crack.

Identify the underlying issue before selecting the waterproofing product.

2. Consider the Surface Material

Different surfaces require different treatment methods. Concrete, cement plaster, masonry, and previously coated surfaces may have different preparation and compatibility requirements.

Check whether the waterproofing product is approved for the surface you intend to treat.

For weak, dusty, contaminated, or damaged substrates, appropriate cleaning and repairs may be necessary before waterproofing begins.

3. Understand the Application Area

The requirements for a terrace are different from those for a bathroom or an exterior wall.

• Terraces and roofs: Consider rainfall exposure, drainage, standing water, and temperature changes.
• Bathrooms and showers: Assess the need for a continuous waterproofing layer beneath the finished surface.
• Balconies: Consider water exposure, drainage, joints, and the compatibility of the waterproofing system with tile finishes.
• Exterior walls: Identify cracks, rainwater penetration, and the suitability of the proposed coating for exterior exposure.
• Concrete repair: Determine whether a bonding admixture, repair mortar, or separate waterproofing system is required.

Selecting a product according to the application helps avoid using a solution that is unsuitable for the problem.

4. Check Flexibility Requirements

Some surfaces may experience limited movement because of temperature changes, shrinkage, or other factors.

In these situations, the flexibility of the waterproofing system may be important.

Check the manufacturer's specifications for crack-bridging capability, movement tolerance, and approved applications. Do not assume every waterproofing product can accommodate structural movement.

5. Review Product Compatibility

A waterproofing system may involve several materials, such as a primer, repair mortar, waterproof coating, adhesive, and final finish.

These products should be compatible with one another.

For example, if tiles will be installed over a waterproofing layer, verify that the membrane and tile adhesive are compatible and that the waterproofing system is approved for the intended installation.

6. Compare Coverage and Application Requirements

The amount of material required depends on the product, substrate condition, application thickness, and number of coats.

Before purchasing, check:

• Recommended application thickness
• Number of coats
• Coverage per pack
• Mixing ratio, where applicable
• Recoating interval
• Curing time
• Requirements for protective or finishing layers

Calculate the approximate quantity using the manufacturer's stated coverage rather than relying on a generic estimate.
