I used Fibreseal, in black, on the concrete roof of a bomb shelter from WW2 that over the years, regardless of various 'miracle' solutions, has leaked like a sieve. It has been over 12 months since I sealed the roof and there has been no water ingress at all. It was not too easy to apply due to the thickness of the product but once in place it has finally solved the massive leak problem. I recommend Fibreseal unreservedly.

Having used various Kingfisher products (masonry paint, asbestos sealer) with good results over 9 years for a shed near the sea at Dungeness - thought I should say something about the Fibreseal roof repair. I bought a tin in 2015 just in case. Fast forward 7 years to December 2022 - got a leak in my felt flat roof. It's 5 degrees c outside, wind chill is 1 degree. A bit damp too but things will get worse. I ask myself - will this stuff work? It's been on my shelf for 7 years. Label says - can be applied at 5 degrees c. Got on the roof, stirred it, painted it into cracks in the seams. Went on very smoothly. Come the rain - that problem is now fixed. I've just ordered more tins and the scrim tape just in case for next year when I might do the whole roof. I have confidence in these products based on what I've seen so far.

Tried for many years to seal my leaking concrete garage roof with various bitumen based products. Always short lived and never 100% effective. Then discovered Kingfisher Fibreseal. Absolutely brilliant. Took time to apply properly but the results are amazing and been nearly a year now without a leak. Just about to apply a second coat just to be certain over the winter. Have applied to my son's roof with same excellent results. Fully recommended.

Kingfisher FIBRESEAL is a one component solvent based acrylic roof repair compound. The product has a thixotropic formulation which incorporates tough fibrous strands which reinforce the final coating. Kingfisher FIBRESEAL was developed to be an instant waterproof repair to any leakage and will not wash off, even when wet. The coating will cure in cold and wet conditions. (Under water in extreme cases). The acrylic polymers incorporated in the product are extremely ultra violet light resistant and will not embrittle with age.

(Refer to these individual product data sheets for detailed application guidance – published on ourwebsite www.kingfisheruk.com)
Suitable for EXTERNAL maintenance and repair of a wide variety of domestic, commercial, industrial and agricultural buildings including:• Flat and Pitched Roofs,• Corrugated Asbestos,• Roof Lights,• Flashings, Roofing Felt• Gutters, Slate, Asphalt,• Lead, Glasshouses, Metal and Fibreglass.
• An instant remedy for leaking roofs and guttering.• Can be applied successfully in wet conditions.• Will adhere to most common roofing materials.• An ideal product for all roof repairs.• Can be used as a complete roof coating for flat roofs made of roofing felt, asbestos and sheet metal.
The surface must be sound and free of loose or friable materials. To obtain the best result remove all surface debris and surface water using a stiff broom and then power wash (except asbestos). Kingfisher FIBRESEAL roof coating can be successfully applied to a damp surface but as with most coatings it is best applied to a dry surface in dry weather conditions. Where the roof is subject to organic growth this should be removed and the surface thoroughly sanitised with “Kingfisher Bio Wash” to protect against re-growth of fungal spores and embedded roots. Any existing coating must be inspected and adhesion tests carried out to ensure that it is a stable surface for the application of Kingfisher FIBRESEAL.
Temporary repairs: -Kingfisher FIBRESEAL is easily applied using a brush or roller. Treat all details first working thoroughly into hidden crevices and joints. To bridge cracks or where excessive movement may occur, additional reinforcement can be incorporated into the coating by embedding suitable polyester or fibreglass woven fleece between two coats of Kingfisher FIBRESEAL, ensuring that all air bubbles are removed by “stippling in” with the brush. Kingfisher FIBRESEAL can be applied in one coat, but experience has shown that a two coat application ensures greater uniformity of coating thickness.
Whole Roof Membranes: -The surface must be swept clean of all debris and all surface water removed before being inspected, to ensure that the surface is sound and has no hidden defects. Any lichen, moss or fungal growth must be treated with “Kingfisher Bio Wash”. Holes, cracks, joints, or gaps should be bridged as previously described. Allow repairs to dry and then coat the whole surface with either two thin coats of Kingfisher FIBRESEAL at ½ litre/m² or one thick coat at 1 litre/m². Leave to dry.
Corrugated Iron or Metal Roofs: -All rust and loose debris should be removed by wire brushing. The whole roof should then be primed using Kingfisher K-X11 and a cement slurry coat (Neat K-X11 mixed with ordinary Portland cement in the ratio 1:1.5) Apply two coats of primer, allowing each coat to cure before applying 1 coat of Kingfisher FIBRESEAL at a rate of 1 litre per m².
Kingfisher FIBRESEAL is waterproof as soon as it is applied and will not wash off but full cure takes 2-3 days depending on temperature. Do not walk on membrane until full cure is obtained.
Kingfisher FIBRESEAL in its liquid form is hazardous to the aquatic environment so must be handled responsibly. Empty and dry residue containers can be disposed of at an ordinary refuse tip. All remaining material in the container must be fully cured, (e.g. by painting out onto waste cardboard or similar) before disposal.
Store in original packaging in a cool dry place away from ignition sources, out of direct sunlight and protect from frost. Keep out of reach of children.
The product has a shelf life of 9 months from the date of manufacture, subject to correct storage conditions.
“Fibreglass compatibility”. This product will bond tenaciously to most fibreglass roof sheets and roof “lights” installed in pitched roof scenarios. However, some fibreglass or “GRP” flat roofing systems include a hard resin “Top Coat” of a density and smoothness which inhibits the adhesion of remedial coatings. Such surfaces can be machined (with coarse grit paper) to improve “key” but adhesion integrity and lifespan can be unpredictable compared to more porous substrates. Application to such impervious surfaces is at user’s own risk.
• Wear disposable gloves and overalls during preparation and application.• Avoid contact with skin and eyes.• If contact occurs wash immediately with plenty of water.• Keep out of reach of children.• Ensure good ventilation during application and drying.
