{"product_id":"watco-black-top","title":"Watco Black Top","description":"\u003cp\u003eWatco Black Top is a bitumen-based surface dressing for refreshing old asphalt and tarmac. It dries to a black, low-sheen finish, covering faded areas, old marks and staining to improve the appearance of suitable car parks, drives, paths and roads.\u003c\/p\u003e\n\u003cp\u003eThe single pack formulation is applied by roller in one coat. It is useful where the existing asphalt is sound but looks tired, and a black surface treatment is preferred to a coloured asphalt paint. Black Top is a coating rather than a repair mortar: holes, weak material and significant damage need to be repaired before the surface is dressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBlack, low-sheen finish for sound bitumen-based surfaces.\u003c\/li\u003e\n\u003cli\u003eNormally one roller-applied coat.\u003c\/li\u003e\n\u003cli\u003eRefreshes the appearance of older asphalt and tarmac.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eThe surface must be dry and free of loose material and contamination.

It is intended for bitumen-based substrates and can soften surfaces containing coal tar. Where uncertain, apply a trial and check after twenty-four hours. Rain can trap solvents and prolong drying. The product is flammable: follow the label and current safety instructions, ventilate the work area and keep away from ignition sources. Store away from heat and protect from freezing.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill Black Top repair potholes?\u003c\/strong\u003e\u003cbr\u003eNo. It is a surface dressing for sound asphalt, so repair holes and weak areas with an appropriate repair material first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it an asphalt paint?\u003c\/strong\u003e\u003cbr\u003eIt is a bitumen-based black surface dressing.
