Frequently Asked Questions

Can Impermax be used on pitched roofs?

Pitched roofs/ flat roofs/ old felt roofs, when combined with a selection of the correct primer allows Impermax to be applied to most surfaces. PU Primer for non absorbent, and Humidity Primer for absorbent substrates.Impermax is self levelling, but with the addition of Thixotropic agent removes the self levelling properties of Impermax and allows it to be applied to up-stands and slopping roofs.

Can Impermax Repair, Encapsulate & Waterproof Asbestos Roofs?

Impermax is used extensively for repairing and extending the life of asbestos roofs. The traditional alternative involves drilling, over cladding. Removal of asbestos sheeting within industrial & normal roofing structures cannot be performed without the disturbance of asbestos particles. The roof is cleaned, primed and coated with a 2 x 1kg/m² layer of Impermax. The result is a low cost solution, approved by health and safety & water authorities, plus a 15 year insurance backed guarantee can be arranged.

Can Impermax withstand foot traffic?

Impermax will withstand occasional foot traffic e.g. for window cleaners or maintenance. If regular traffic is expected then a final coat of Colodur, a hard wearing top coat is recommended. This system can be made none slip by adding Quartz granules etc to the Colodur.

Is Impermax a single component?

Impermax has been formulated as a single component resin. Once the Impermax can is opened and stirred, the resin can then be applied.

What manufactures guarantees are available?

The BBA and ETA (European Technical Authority) certify the Impermax 10 year system. The ETA certifies the Impermax 25 year system. Krypton Chemicals offer written guarantees against failure of the Impermax membrane, please contact Krypton Chemicals UK for details.

Does Impermax require reinforcement fleece?

The 10 year BBA & ETA approved system is for primer plus 2 coats of Impermax. Reinforcement by fleece is not required other than in damaged areas of the substrate and to reinforce the base of up-stands. The 25 year system incorporates a fleece requirement and an additional 1Kg m/² Impermax coating.

Can Impermax absorb movements in substrates?

Impermax is a BBA approved system stretching up to 400%, therefore significant movements in the building can be absorbed.

What colours is Impermax available in?

Stock colours available are Dark Grey & Black. However Impermax can be manufactured in almost any RAL colour, minimum batch size is 1000kg

If the project requires a particular colour then we advise the simple application of the single component PU top coats Colodur, with the appropriate colour pigment added.

Does my roofing insulation need to be upgraded?

Repairing a roofing structure can seem a daunting process; however Krypton Chemicals offers an easy, hassle free roof repair option.

Impermax can be applied and fully installed without the need to remove the existing roof. Roofing insulation does not require to be upgraded to legally conform to current building regulations. Therefore it gives you the option to weigh up the pros and cons to upgrading you roofing insulation. If upgrading your thermal insulation is a project requirement, the available system is recommended;

Does the old roof need to be stripped?

A number of considerations must be analysed in order to answer the above question…

Krypton Chemicals has designed a highly adaptable waterproofing resin… Impermax, which is compatible with both PU and Humidity Primers. In the typical of cases there is no need to strip the existing roof. With the aid of the correct primer Impermax totally adheres to the substrate moulding over all fissures, coating with a tight waterproofing membrane. Impermax holds 400% elongation and flex’s to the movement of the roof, while providing a breathable waterproof membrane.

To correct accurate installation the substrate must be comprehensively cleaned of all debris and containments. Geomax fleece must be used to cover all fissures and the base of up-stands; due to the light weight nature of this membrane the roofing substrate does not require additional structural support.

Is there a non-slip, hard wearing coating option?

For the requirements of hard wearing, high point load resistant or anti-slip surfaces, such as indoor tennis courts or car parks. Krypton Chemicals offers a wide range of non-slip, wear resistant top coating selections, available in any RAL colour, and numerous textures and finishing's.

Are product presentations available?

A range of product presentations are accessible. For large projects areas we recommend you contact Krypton Chemicals to discuss product suitability, specifications and schedule a project site visit from one of are fully trained technical team.

Why Use Cold- Applied For repair?

Impermax is a cold applied liquid resin, providing a cost effective waterproof membrane. There are many advantages to using the cold applied Impermax, as summarised below;

• Cost Effective
• Non - Flammable
• Permeable to water vapour (allows vapour to escape from substrate)
• Low Maintenance
• Highly Durable
• No additional substrate structural reinforcement is required
• Holds BBA & ETA approval
• A solvent free formulation is available

What is Cold- applied Liquid Waterproofing?

Historically the most common method for waterproofing a flat roof was "hot-applied" I.e. torched molten bitumen, melted to create a waterproof membrane.

However with modern technology and chemical developments "cold-applied" has no direct fire risk as this method involves the use of cold liquid resin seamlessly coat to intertwine the substrate with the rapid curing waterproof membrane.

Will Impermax Melt in the hot weather?

Impermax is totally non-thermoplastic, it will not melt, bubble even in the hottest Mediterranean or Middle Eastern sun shine.

What are the typical project costs when using Impermax?

Impermax is an extremely cost effective waterproofing resin that provides long term performance.

Calculating the typical project costs can be tricky. Impermax not only providse long-term benefits but also reduces the installation and labour costs. Impermax has BBA & ETA approved carrying either a 10 or 25 year guarantee.

For detailed project costing please contact Krypton Chemicals, but on the whole when comparing Impermax against re-roofing costs and other waterproof roofing systems Impermax is significantly cheaper option, especially if we tailor in labour costs, installation time. In many cases Impermax can be coated directly over the existing system.

What are the concealed benefits?

There are many long-term advantages to using Impermax including, its immense structural strength, durability as well as its low maintenance.

However there are some hidden complex benefits also;

• Cold applied - no Fire Risk
• Cut roof preparation time
• Cost Effective
• Rapid installation with minimal disruption to the workforce or production levels.
• Solvent Free Option- Impermax 2K
• Reduced Labour Costs
• Often no requirement to remove the existing (failed) roof system.

What are the Benefits of Cold-Applied?

Cold - applied resin solutions offer many benefits in comparison to hot applied systems, as there are no fire risks, or insurance policy issues.

Utilising the correct primers cold - applied Impermax totally bonds with the substrate, creating a long-life waterproofing membrane, cutting installation time, labour and maintenance costs and extending the life expectancy of the waterproofed substrate.

Is There a Non- Solvent Version of Impermax?

Impermax 2K is a two component spray applied waterproof resin offering added benefits of rapid cure (totally dry in seconds) plus rapid application at 2Kg/m² in one application.

Can Impermax be in contact with drinking water?

Impermax has APPLUS certification for contact with potable water, it can be used e.g. to waterproof reservoirs for drinking water.

Why use Cold-applied for new build?

There are many advantages to the implementation & installation of cold- applied waterproofing membrane to new build roofing projects, as summarised below;
