Professional Surface, Tool & Bond Preparation

A bond is only as reliable as the surface underneath it. Oil, grease, fingerprints, dust, silicone residue & workshop contamination can interfere with adhesives, sealants, primers & coatings, making proper cleaning an important part of professional surface preparation.

Different surfaces call for different cleaning methods. The Sika range at Industrial Shed includes specialist products for metal bond faces, automotive glass, non-porous substrates, tools, equipment & hands across fabrication, construction, automotive & workshop applications.

Start by identifying what you're cleaning, what's contaminating it & what happens next. Preparing stainless steel before adhesive bonding is a different job from cleaning a windscreen bond area or removing fresh material from application tools.

For adhesives, sealants & related products used after preparation, explore Adhesives & Tapes.

What Are Sika Cleaning Agents?

Sika cleaning agents are specialist products used to remove compatible contamination from substrates, equipment or hands before, during or after professional bonding, sealing & maintenance work.

Depending on the product, they can assist with:

► Cleaning surfaces before bonding
► Preparing compatible non-porous substrates
► Cleaning automotive glass
► Removing fingerprints, grime & suitable residues
► Preparing light metals & alloys
► Cleaning steel & stainless steel
► Cleaning tools & application equipment
► Removing suitable fresh adhesive or sealant residue
► Cleaning hands during trade work

A glass-cleaning product, solvent cleaner & hand-cleaning wipe don't perform the same job. Match the product to the substrate, contamination & following process rather than treating every cleaner as interchangeable.

What's in the Sika Cleaning Agents Range?

The collection includes specialist Sika products such as:

► Sika Cleaner PCA
► Sika Cleaner-350H Hand Wipes
► Sika Cleaner H-1
► Sika Cleaner G+P
► Sika Colma Cleaner – 1L
► Sika Colma Cleaner – 20L

Together, these products cover several distinct cleaning tasks rather than one type of general-purpose degreasing. Workshops, installers & maintenance teams can choose products for bond-face preparation, glass cleaning, hand cleaning & equipment clean-up according to the job.

Which Sika Cleaner Should You Choose?

The material in front of you is the best place to start.

Once the cleaner is narrowed down, check the requirements for the exact substrate & product being applied afterwards. Paints, plastics & other sensitive surfaces may require compatibility testing before proceeding.

Sika Colma Cleaner – Bond Faces, Tools & Metal Surfaces

Metal can look spotless while still carrying oils or workshop residue that shouldn't remain beneath an adhesive.

Sika Colma Cleaner is a one-component, grease-free solvent cleaner formulated for pre-cleaning suitable bond faces plus cleaning tools & equipment.

Typical surfaces identified by Sika include:

► Steel
► Stainless steel
► Light metals
► Alloys
► Suitable bonding surfaces
► Tools
► Application equipment

Available in 1L & 20L formats, Colma Cleaner suits anything from occasional preparation work through to regular workshop or project use.

Where Does Colma Cleaner Fit?

Consider Colma Cleaner when the work involves:

► Preparing suitable metal before bonding
► Cleaning fabrication components
► Removing compatible contamination from bond faces
► Cleaning tools after working with suitable uncured Sika materials
► Workshop adhesive work
► Industrial assembly
► Sealant application
► Repair operations involving compatible epoxy products

For related bonding & sealing materials, Adhesives & Tapes provides a practical next step once the specified preparation is complete.

Cleaning may not be the final preparation stage. Depending on the substrate & Sika adhesive or sealant being applied, activation, priming or additional surface preparation may still be required.

Sika Cleaner G+P – Glass, Plastics & Non-Porous Surfaces

Glass needs more than a quick wipe when the cleaned area will become part of a bonded installation.

Sika Cleaner G+P is a water-based cleaner containing isopropanol for compatible glass, plastics & other non-porous substrates.

Relevant applications include:

► Vehicle glass
► Selected plastics
► Compatible non-porous surfaces
► Screen prints on vehicle glass
► Fingerprint removal
► General grime
► Suitable surface residues

A useful feature of Cleaner G+P is its ability to make silicone residues visible during cleaning.

Spray, wipe & allow the cleaned surface to dry completely before moving to the next specified preparation stage.

Sika Cleaner PCA – Glass Cleaning & Primer Application

Stubborn contamination on automotive glass sometimes needs physical cleaning rather than simply more liquid cleaner.

Sika Cleaner PCA is a melamine-foam cleaning pad developed for contamination on windshields, ceramic frits & other suitable glass surfaces.

It can assist with:

► Ceramic frit contamination
► Label residue
► Suitable glass contamination
► Windscreen bond-area preparation
► Application of certain Sika primers

Cleaner PCA can be used dry or with compatible products such as Sika Cleaner G+P where specified.

Automotive glass is its natural working environment. Cleaner PCA shouldn't be treated as a general abrasive pad for every material, particularly sensitive plastics or finishes.

Sika Cleaner-350H – Hand Cleaning for Trade Work

Sometimes the material that needs cleaning isn't on the component — it's on the installer.

Adhesives, sealants & other trade materials can make bonding, sealing & repair work messy, particularly when soap & running water aren't immediately available.

Sika Cleaner-350H provides a dedicated hand-cleaning option for professional work environments.

Keeping appropriate hand-cleaning wipes nearby also helps prevent workers from reaching for substrate solvents that aren't intended for skin.

Cleaning Before Adhesive Bonding

A surface doesn't need to look dirty to carry contamination.

Before applying a compatible adhesive, inspect for:

► Oil
► Grease
► Dust
► Fingerprints
► Processing residue
► Silicone contamination
► Moisture
► Label adhesive
► Previous material residue
► Loose coatings
► Oxidation or corrosion

The exact preparation process depends on the substrate plus the adhesive being applied.

For steel, stainless steel & suitable alloys, Colma Cleaner can form part of that preparation where specified.

Cleaning Before Sealant Application

Joint preparation can determine whether sealant meets a clean bond face or a layer of contamination.

Construction, fabrication & maintenance work may involve cleaning:

► Metal joints
► Glazing components
► Non-porous surfaces
► Fabricated assemblies
► Repair interfaces
► Installation hardware

After cleaning, check whether the chosen sealant system also requires an activator or primer.

For surrounding repair work on concrete structures, Sika Concrete Repair & Protections provides complementary products where substrate deterioration needs attention before sealing or protection proceeds.

Automotive Glass Replacement

Windscreen preparation is a specialised cleaning job because the cleaned area ultimately becomes part of a bonded safety installation.

Cleaner PCA is designed for contamination on automotive glass & ceramic frits, while Cleaner G+P provides a compatible cleaning option for glass plus other suitable non-porous substrates.

Typical tasks include:

► Windscreen bond-area cleaning
► Ceramic frit preparation
► Removal of suitable label residue
► Cleaning screen prints
► Detecting silicone contamination
► Preparation before specified activation or priming

Allow the glass to dry completely before moving to the next specified preparation stage.

Fabrication & Metalworking

Machining, handling & storage can leave invisible contamination on components long before assembly begins.

Fabrication work can introduce:

► Cutting oils
► Handling residue
► Workshop grime
► Dust
► Grease
► Processing contamination

Where suitable, Colma Cleaner provides a dedicated cleaning option for light metals, alloys, steel & stainless steel before bonding.

For assemblies combining adhesive bonding with mechanical fixing, Bolts & Fasteners provides complementary fastening options.

Industrial Repair & Maintenance

Repair crews often need to clean twice — once before the repair & again before the tools are put away.

Suitable Sika cleaning products can support work involving:

► Epoxy repairs
► Adhesive bonding
► Sealant replacement
► Protective coating maintenance
► Equipment repairs
► Fabricated components
► Tool clean-up

Sika specifies Colma Cleaner for cleaning uncured material from equipment used with several of its epoxy & coating systems. Once these materials cure, mechanical removal may be necessary.

For jobs continuing into surface protection after repair, Sika Protective Coatings & Linings provides a related Sika product range.

Construction & Remedial Work

Dust, previous repairs & multiple trades can leave a surface looking very different by the time bonding or sealing begins.

Cleaning may form part of preparation for:

► Concrete repairs
► Metal component bonding
► Joint sealing
► Glazing
► Protective work
► Equipment installation
► Adhesive fixing

Where concrete itself is damaged, contaminated or deteriorated beyond basic cleaning, Concrete Repair & Restoration provides products for the repair stage.

Workshop Assembly & Equipment Maintenance

A clean bench helps, but the bond face itself still needs the preparation specified for the material.

Workshop uses can include:

► Component assembly
► Metal bonding
► Tool cleaning
► Sealant work
► Adhesive repairs
► Maintenance tasks
► Equipment clean-up

For holding suitable components securely during cleaning, assembly or repair, Shop Presses & Vices can support the surrounding workshop setup.

Clean First or Abrade First?

Chemical cleaning & mechanical preparation solve different problems.

Cleaning can address contamination such as:

► Oil
► Grease
► Fingerprints
► Suitable residues
► Workshop grime

Mechanical preparation may instead be needed for:

► Rust
► Scale
► Loose coatings
► Oxidation
► Hardened adhesive
► Irregular surface layers
► Mechanically unsound material

Heavy grease may need to be removed before abrasion so it isn't spread across the surface. Dust created during grinding or abrasion then needs to be removed before the specified chemical preparation continues.

A cleaner can't make a loose or corroded surface mechanically sound.

Cleaning, Activating & Priming – What's the Difference?

Three bottles can sit beside each other on the bench while performing three very different jobs.

Cleaning

Removes compatible contaminants from the substrate.

Activating

Provides an adhesion-promoting treatment for particular substrates where the bonding system specifies it.

Priming

Creates a specified interface between particular substrates & the adhesive or sealant system.

A preparation sequence may therefore involve:

inspection → mechanical preparation where required → cleaning → activation or priming where specified → bonding or sealing

Not every substrate requires every stage.

How to Choose a Sika Cleaning Agent

Identify the Material

Start with the component rather than the cleaner.

Confirm whether you're working with:

► Glass
► Ceramic frit
► Steel
► Stainless steel
► Light alloy
► Plastic
► Painted material
► Another compatible non-porous substrate

Work Out What's on the Surface

Different contaminants need different responses.

Look for:

► Grease
► Oil
► Dust
► Silicone residue
► Fingerprints
► Label residue
► Adhesive residue
► Workshop grime
► Processing contamination

Consider What Happens Next

Cleaning a tool before storage isn't the same process as preparing a structural bond face.

The next operation may involve:

► Adhesive bonding
► Sealant application
► Primer application
► Activation
► Automotive glass installation
► Component assembly
► Protective coating
► Tool storage

Check Compatibility

Strong cleaning action isn't useful if it damages the material underneath.

Painted surfaces, plastics & other sensitive materials can respond differently to solvent or mechanical cleaning.

Test the actual substrate where Sika requires compatibility verification.

Match the Format to the Workload

Occasional repairs & repetitive workshop cleaning don't consume product at the same rate.

Industrial Shed carries Colma Cleaner in 1L & 20L formats, while other Sika cleaners are supplied as specialised pads, wipes or application-specific products.

Practical Cleaning Tips

Remove Heavy Contamination First

Don't turn a clean wipe into a grease spreader.

Remove heavy contamination using the appropriate method before carrying out the final specified cleaning process.

Use Fresh Wiping Material

Yesterday's residue shouldn't end up on today's bond face.

Use clean, suitable wiping material where the cleaner requires a wipe-off process.

Avoid Cross-Contamination

Putting contaminated material back into clean product can compromise future preparation work.

Dispense cleaning products according to their instructions rather than repeatedly introducing dirty cloths or tools into the container.

Respect Flash-Off & Drying Time

A wet-looking clean surface isn't necessarily ready for adhesive.

Allow the specified drying or flash-off period before applying the next preparation product, adhesive, sealant or coating.

Sika specifies a minimum flash-off period for Colma Cleaner, so the next stage shouldn't begin immediately after application.

Test Sensitive Materials

Plastic, paint & decorative finishes deserve more caution than bare workshop steel.

Where compatibility isn't established, test the cleaner on a small inconspicuous area as directed before treating the complete component.

Deal With Fresh Material Promptly

Uncured residue is generally easier to remove than hardened adhesive, grout or coating.

Sika specifies Colma Cleaner for cleaning equipment used with a number of compatible uncured products. Once material has cured, mechanical removal may be required.

Protect Yourself During Cleaning Work

Surface preparation can involve solvents, chemicals, dust & freshly applied construction materials.

Before starting:

► Read the current product label
► Review the Safety Data Sheet
► Check ventilation requirements
► Wear specified gloves, eye protection or other PPE
► Follow fire precautions for flammable products
► Store products correctly
► Keep substrate solvents away from skin

Personal Protective Equipment provides supporting protection for workshop, construction & maintenance work.

Where concrete preparation creates additional dust or site hazards, Protective Equipment For Concrete Work provides another relevant range.

For help understanding chemical handling information before work starts, read How to Read a Safety Data Sheet - A Quick Guide for Workshop Operators.

Prepare the Whole Job Before Final Cleaning

The cleanest bond face can be contaminated again while someone searches the workshop for the adhesive, primer or missing applicator.

Have the required:

► Cleaner
► Fresh wiping material
► PPE
► Abrasives where specified
► Activator or primer where required
► Adhesive or sealant
► Application equipment
► Waste container
► Product documentation

ready before completing the final preparation stage.
