    Product Details

    WATERPROOFS INSTANTLY – If water is getting in, Polar FeltSeal will keep it out. Seal any leaks and cracks on your felt roofs. If it rains immediately after application – it will have no adverse effect.

    ONE COAT – Just one coat to exposed areas and waterproofs them instantly. If you have a leak, FeltSeal will fix it – and keep it fixed for a long time to come. 500ml covers up to 0.5m² and 1 Litre covers up to 1m².

    REINFORCED FIBRES – Black & Grey FeltSeal contains reinforced fibres that interlace to cover up small gaps or crack, giving durable and quick results.

    NO PRIMER NEEDED – Easy application and no primer needed which can be applied to damp surfaces. An easy solution for emergency roof repairs and water leaks.
