Flexistop

Because an ingredient added to the formula prevents it curing to a fully rigid state for many, many decades, expanding and contracting along with your property in heat and cold, providing a strong, waterproof seal. Almost every other roofing product goes rigid and brittle, cannot cope with movement in the building caused by heat, cold and external causes, then cracks and fails, allowing water through.

In many cases, such as when repairing a leaking felt roof, home-owners have carried out their own repairs. More complicated jobs can be done by competent handymen with experience in the building trade. If you contact us on 091 445 544 or info@mspcoatings.ie and tell us your own situation we will advise you as to your best course of action.

A roofer has described working with FlexiStop^TM as “the low-tech application of a high-tech product”. Very often over the years, the answer has been “Yes”. Again, call or email us on 091 445 544 or info@mspcoatings.ie and we will advise you.

FlexiStop^TM is like a thick paint and is applied with a brush or roller.

No. FlexiStop^TM cures in about two hours, and gives you plenty of time to work with. Some products need to be worked super fast, or go off on the brush or roller. This will not happen with FlexiStop^TM.

All surfaces to be coated must be clean and perfectly dry. FlexiStop^TM is designed to last a minimum of 35 years in almost every known climate. Remove all loose debris and dirt, any oils and grease by vigorous scrubbing or power-washing. Then dry the clean surface, using towels or heat if necessary.

? FlexiStop^TM has been successfully used on concrete, felt, asphalt, slates, fibreglass, tiles, asbestos, timbers, corrugated iron, steel, lead, metal profile, copper, aluminium, etc. Some substrates, such as uPVC and EPDM membranes require the use of a self-etching primer beforehand. Some of the metals listed above may need a light sanding in order to provide a “key”.

Yes. See answer above.

Yes you can, but you should first use a sealer primer (we recommend “WeatherStop^TM”) which will both seal the timber, provide a good “key” for FlexiStop^TM to adhere to, and should reduce the quantity of FlexiStop^TM needed by lowering the absorbency of the timber.

No. FlexiStop^TM can be permanently submerged in water for decades without any defects occurring. In our office we have a cardboard box, which we lined on the inside with FlexiStop and filled with water… back in 2013 – and the water is still sitting there!

FlexiStop^TM should best be applied at 5^oC or above. If applying in low temperatures first ensure all frost related moisture is removed and the surface is dry.

A good skin should typically form in about two hours, although this will vary depending on temperatures and humidity. Once it has been applied for an hour or so a light rain-shower should not affect it. It is recommended that you allow 24 hours before recoating. Do not apply FlexiStop^TM if heavy showers or persistent rain is imminent. In cases of extreme urgency we can add a fast acting catalyst that will greatly speed up the curing time. Call or email us on 091 445 544 or info@mspcoatings.ie for more information.

Standard available colours are Grey, Black & Clear. FlexiStop^TM can be applied in any colour, to order, if a minimum quantity of 100 litres is ordered.

No. It can be also used on sloped roofs, and can actually be painted on to vertical surfaces, such as parapet walls and on gable walls adjoining flat roofs, forming a seamless membrane from the wall across the roof. Like a thick oil paint it will “run” if applied too thickly, so two or even three very light coats might be recommended, depending on the circumstances.

Typically, two coats of FlexiStop^TM, or one thick coat, will be achieved using 1 Litre per Msq (a single 5 Litre can should therefore cover about 5Msq). This varies from substrate to substrate, depending on porosity or what you want to achieve. Call us or email us on 091 445 544 or info@mspcoatings.ie and we will give you an estimate of the amount of product required.

If you do the mathematics, that coverage rate provides a coating that is 0.025mm thick. FlexiStop^TM, applied at the rate suggested in No. 14, above, gives a coating 40 times thicker – and stronger.

Simply replace the lid tightly, using the clamp provided, and the product should be still good to use for up to twelve months.

No. FlexiStop^TM is UV resistant and is not affected by temperatures from -60^oC to + 200^oC. It remains flexible and pliable almost anywhere on planet Earth.

You will neither be able or need, to paint FlexiStop^TM. See the answer to Question 18.

Yes. FlexiStop^TM is completely vapour permeable, allowing any moisture in the building or substrate to evaporate, while preventing any dampness penetrating from the exterior.

Yes. Larger gaps can be bridged using a fleece that has been embedded in a prior coat of FlexiStop^TM and then coated along with the rest of the surface to be treated.

Yes. A light coat of Flexistop^TM should be applied, a fleece embedded into this and, when cured a second coat of FlexiStop^TM applied to that. This will provide an extremely strong, flexible surface.

Some substrates will require or benefit from a prior application of a primer/sealer. These, typically, are uPVC or EPDM membranes, and timber sheeting (see answers to question 5 & 7 above).

Yes. Surfaces should first have all traces of rust removed, and a rust kill/inhibitor applied. Then apply FlexiStop^TM as recommended.

“Yes”, is the short answer. However, asbestos brings with it a whole range of hazards, requirements and regulations. Like any substrate, however, once asbestos is clean and dry, FlexiStop^TM can be successfully used provided all recommended precautions are observed.

Yes.  Though this may be done more easily and less expensively with WeatherStop. Call or email us on 091 445 544 or info@mspcoatings.ie for more information.

Yes. FlexiStop^TM has passed all water leaching tests and can be used to harvest or contain water fit for human and animal consumption British Standard BS6920 (Test on Effect of Water Quality) applies.

Yes. Although nothing will adhere to FlexiStop^TM, including moss, algae etc., it can be cleared of debris (bird droppings, etc.) by powerwashing, though the jet should not be applied too close to the surface. A simple brushing along with the use of a garden hose will be just as effective.

Yes. FlexiStop will withstand casual foot traffic, such as when a roof needs to be accessed by maintenance personnel. If an area of a roof is intended for use as a designated walkway, suitable matting should be laid there. Flagstones can be placed on top of FlexiStop^TM without causing damage as long as care is taken that all sharp objects or debris that might penetrate the coating are carefully removed beforehand.

Yes. FlexiStop^TM has been independently and scientifically evaluated for Fire Retardant Qualities (BS476 & BS6853), Vapour Permeability (6931), and Effect on Water Quality (BS 6920) and carries relevant certificates in these categories.

We have never come across a case of birds eating FlexiStop^TM, but if an area of FlexiStop^TM is damaged on a roof or other surface you should remove any loose product and paint the cleaned area again, continuing on to the undamaged surface for about 100cm/4 inches in all directions. The only thing that sticks perfectly to FlexiStop^TM is FlexiStop^TM!

Yes. FlexiStop^TM will adhere to the substrates involved. Caravans and mobile homes are susceptible to movements caused by road travel and exposure to wind – because FlexiStop^TM remains flexible for many, many decades it is ideal for use in this case.

We will offer training courses to selected candidates who have a proven history of providing quality service to the public in the roofing/construction/maintenance fields. If you feel you meet these qualifications, contact us on 091 445 544 or info@mspcoatings.ie.
