Waterproofers & Building Chemicals

About Waterproofers & Building Chemicals

Waterproofers and building chemicals are essential protective products that prevent moisture damage, enhance concrete performance, and ensure construction projects deliver lasting quality. This comprehensive category at MyToolShed.co.uk encompasses specialist solutions including damp proof membranes, tanking systems, cement bonding agents, PVA adhesives, bitumen coatings, and concrete additives. Whether undertaking new build projects, renovation work, or essential maintenance tasks, selecting the right waterproofing solutions is crucial for preventing costly water damage and achieving professional, durable results.

MyToolShed.co.uk stocks trusted brands like Everbuild and Ronseal, delivering proven performance across diverse applications. From waterproofing wet rooms and tanking basements to protecting flat roofs, stabilising friable surfaces, and improving concrete strength, these specialist products address the specific challenges faced by tradespeople on site. The Everbuild Black Jack range offers bitumen-based solutions for roofing and below-ground applications, whilst modern acrylic systems like Evercryl and Aquaseal provide quick-drying, flexible waterproof membranes ideal for bathroom installations and basement conversions.

Applications

Waterproofers and building chemicals serve a wide range of professional trades and applications:

• General Builders: Damp proofing, tanking basements and cellars, improving concrete performance on new builds, extensions, and renovation projects requiring moisture protection
• Plasterers and Renderers: Using bonding agents, stabilising solutions, and PVA products to prepare substrates and improve adhesion
• Roofers: Applying bitumen coatings, felt adhesives, and all-weather protective treatments to flat roofs and weatherproofing applications
• Bathroom Fitters: Installing tanking membranes and waterproof systems for code-compliant shower enclosures and wet rooms
• Groundworkers: Adding frostproofers, accelerators, and integral waterproofers to concrete mixes for improved durability and winter working
• Property Maintenance Professionals: Diagnosing and treating damp issues, repairing deteriorated concrete, and applying protective coatings
• DIY Enthusiasts: Tackling home improvement projects including bathroom renovations, garage waterproofing, and general building repairs

Choosing The Right Waterproofers & Building Chemicals

When selecting waterproofing products and building chemicals, consider these essential factors:

• Application Type: Match products to specific requirements – tanking membranes for wet rooms, bitumen products for roofing, PVA bonds for sealing tasks, and integral waterproofers for concrete mixes
• Substrate Compatibility: Ensure products suit your surface material. Stabilising solutions work on powdery surfaces, whilst cement bonding agents help new concrete adhere to existing structures
• Environmental Conditions: Winter working requires frostproofers or accelerators. External applications need UV-resistant, all-weather formulations
• Coverage Requirements: Calculate area to treat and check coverage rates. Larger 5-litre containers offer better value for bigger projects
• Drying Times: Modern tanking membranes may be tiled over within hours, whilst others require 24-48 hours curing. Plan workflow accordingly

Safety Information

Many waterproofing products contain substances requiring careful handling. Always read the product safety data sheet before use and ensure adequate ventilation when working with bitumen-based products, adhesives, and chemical additives. Wear appropriate PPE including chemical-resistant gloves, safety glasses, and respiratory protection where recommended, particularly in confined spaces like basements or cellars. Follow dosage instructions precisely when adding chemical additives to concrete mixes, as exceeding recommendations can adversely affect strength and curing times.

Frequently Asked Questions

Can I use PVA bond as a waterproofer?

Whilst PVA bonds reduce porosity, they shouldn't be relied upon as primary waterproofing solutions. Standard PVA can re-emulsify when exposed to sustained moisture. For genuine waterproofing applications like wet rooms or basements, always use dedicated tanking membranes specifically formulated for those demanding applications.

How long does tanking membrane take to dry before tiling?

Most modern acrylic-based tanking membranes are touch-dry within 1-2 hours and typically can be tiled over after 4-6 hours, or when fully changed from wet colour to cured colour. Always check manufacturer datasheets for specific guidance, and allow additional time in cold or humid conditions.

When should I add frostproofer to concrete mixes?

Add frostproofer when air temperatures are forecast below 5°C during the critical curing period. It accelerates initial setting and depresses the freezing point of water within the mix. However, still protect newly laid concrete with insulating covers during prolonged cold weather, particularly for structural applications.
