Surface Treatments

About Surface Treatments

Surface treatments are essential preparation and maintenance products designed to clean, protect, and restore surfaces before painting, sealing, or general upkeep. Whether working with exterior masonry, UPVC windows and doors, timber cladding, or interior walls, the right surface treatment ensures optimal adhesion of subsequent coatings and helps prevent issues like mould growth, algae, and surface degradation. MyToolShed.co.uk stocks professional-grade surface treatments from trusted brands like Everbuild, formulated to meet the demands of UK tradespeople and serious DIY enthusiasts.

From fungicidal washes that eliminate biological growth on external walls to specialist UPVC solvent cleaners that restore plastic window frames, these products save time, improve finish quality, and extend the lifespan of protective coatings. Proper surface preparation is the foundation of any successful decorating or maintenance project, removing contaminants and creating the ideal substrate for long-lasting finishes in all British weather conditions.

Applications

Surface treatments are indispensable for a wide range of trades and applications, including:

• Painters and Decorators: Preparing exterior walls, rendering, and masonry before applying paint or textured coatings
• Window Fitters: Cleaning UPVC frames after installation and removing sealant residue and protective film adhesive
• Building Maintenance Contractors: Regular cleaning and treatment of commercial and residential properties
• Rendering Specialists: Treating walls affected by algae or mould before applying new render systems
• Roofers: Treating and cleaning fascias, soffits, and bargeboards before repainting
• Property Managers: Maintaining the exterior appearance of rental properties and housing stock
• Homeowners and DIY Enthusiasts: General property maintenance, cleaning, and preparation work

Choosing The Right Surface Treatments

Selecting the appropriate surface treatment depends on several key factors. First, identify your substrate – masonry, render, timber, UPVC, or metal – as each material requires specific formulations to avoid damage whilst achieving effective results. Always verify product compatibility before application.

Consider the specific problem you're addressing. For biological growth such as mould, algae, or lichen on exterior walls, a fungicidal wash kills spores and prevents regrowth. For cosmetic cleaning of UPVC windows and doors, a solvent-based cleaner removes stubborn marks without affecting the material's integrity or colour.

Application method matters too. Some treatments work best when brushed or rolled on, whilst others require spraying and rinsing. Check dilution requirements and coverage rates per litre to calculate project costs accurately. Weather conditions are particularly important for exterior applications – many products require dry conditions and temperatures above 5°C for effective action. MyToolShed.co.uk provides detailed technical specifications to help you choose products that deliver professional results every time.

Safety Information

Surface treatment products contain active chemical ingredients and must be handled responsibly. Always read the product label and safety data sheet before use, paying particular attention to COSHH regulations applicable to chemical handling on UK sites. Many surface treatments contain biocides, solvents, or alkalis that can cause skin and eye irritation.

Wear appropriate PPE including chemical-resistant gloves, eye protection, and respiratory protection if working in enclosed spaces or when spraying. Ensure adequate ventilation when using solvent cleaners indoors. When working on exterior surfaces, protect surrounding vegetation, paving, and water features from product run-off.

Frequently Asked Questions

How long does fungicidal wash take to work?

Most fungicidal washes require 24-48 hours to fully kill mould and algae spores. Apply to dry surfaces, allow the recommended contact time, then rinse thoroughly or leave to weather naturally depending on the product formulation. Wait at least 48 hours after treatment before applying paint or coatings.

Can I use UPVC solvent cleaner on coloured window frames?

UPVC solvent cleaners are generally safe for both white and coloured frames, but always test on an inconspicuous area first. Apply with a cloth rather than spraying directly, and avoid excessive rubbing which could damage decorative foils on coloured frames.

How much coverage can I expect from surface treatment products?

Coverage varies depending on surface porosity and product concentration. Fungicidal washes typically cover 5-10 square metres per litre on porous masonry when diluted as directed. UPVC cleaners used neat may treat 15-20 square metres per litre. Always check the technical data sheet for specific coverage rates.
