Can Sika products from different categories be combined in the same project?

Yes, it's common to combine several categories within the same project, such as in a bathroom renovation.

Sika Product Guide: What to Use for Each Construction Project

Q: Where do I start if I don't know which Sika product I need?

First identify the problem (joint, leak, deteriorating façade) and check the category table, which links to the guide with specific products.

Q: Are Sika products only for professionals?

Not all of them: some are designed for advanced DIY and others require professional application due to their technical complexity.

Quick answer: Sika covers four major needs on site and in renovation projects: sealing joints and bonding pieces (Sikaflex), waterproofing roofs, terraces, bathrooms, and concrete, protecting and reinforcing concrete against wear and carbonation, and supporting façade insulation systems with anchors and profiles. This guide takes you straight to the category you need.

What Do You Need to Solve?

Situation	Guide
Sealing an expansion joint or bonding a piece with immediate grab	Sikaflex: Sealants and Adhesives
A terrace or roof with leaks, or a specific problem spot (gutter, chimney)	Waterproofing Roofs and Terraces
A construction or expansion joint in a wall, slab, or reinforced concrete tank	Expansion Joints and Watertightness
Waterproofing the shower before tiling, or bonding a few loose tiles	Waterproofing the Bathroom
An exposed concrete façade that's deteriorating, a tank with chemical attack, or a beam that needs more strength	Concrete Protection and Reinforcement
An external façade insulation project (ETICS)	ETICS Accessories and Anchors

A Common First Step: Cleaning

Before applying any Sika sealant, waterproofer, or coating, the surface must be clean, dry, and free of dust or construction debris. Sika® Limpa is the brand's professional cleaner for this preparation step, available in 5 and 25 kg containers depending on the size of the project.

Professional or DIY: Who Can Apply Each Product

Frequently Asked Questions

Where do I start if I don't know which Sika product I need?

First identify the problem (a joint, a leak, a deteriorating façade) and check the table above: each situation links to the guide with specific products and how to choose between them.

Are Sika products only for professionals?

Not all of them: some are designed for advanced DIY, like Sikaflex sealants or the shower sealing band, while others require professional application due to their technical complexity, like sprayed membranes or structural reinforcement.

Can I mix products from different categories in the same project?

Yes, it's common: for example, a bathroom renovation might combine the sealing band, tile adhesive, and, if you need to seal an expansion joint in the tiling, a Sikaflex suited to damp interiors.
