{"product_id":"watco-fine-crack-filler","title":"Watco Fine Crack Filler","description":"\u003cp\u003eWatco Fine Crack Filler is a pourable epoxy resin for narrow cracks in concrete floors. It fills the line of the crack before coating, helping you prepare a more even surface for floor paint. The two-part, 100% solids formula cures without shrinking and can be painted once it has hardened.\u003c\/p\u003e\u003cp\u003eUse it for fine cracks up to 3mm wide and small holes below 50mm in diameter and 25mm deep. The liquid can be drawn level with a scraper, making it practical for local repairs around a floor before repainting. It suits indoor and outdoor concrete, with a grey finish that can be left exposed or coated.\u003c\/p\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRake loose material out of the crack and remove dust, grease and contamination. The crack must be clean and dry so the resin can bond to its sides. Chasing out the crack is not normally necessary. Check the width, depth and condition of the damage before opening the pack.\u003c\/p\u003e\u003cp\u003eNo primer is required. Check the floor temperature as well as the air temperature, especially in unheated buildings.

Scrape the sides and base of the tin as you mix, bringing all the material together until it is uniform. Have the prepared crack and application tools ready before combining the components.\u003c\/p\u003e\u003cp\u003ePour carefully along the crack, then draw a straight edge or plastic or rubber scraper over the repair. Remove excess from the surrounding concrete while it is workable. Allow the resin to harden before applying the floor coating.\u003c\/p\u003e\u003ch3\u003eLimitations\u003c\/h3\u003e\u003cp\u003eThis filler is intended for surface filling. Continuing structural movement can cause a crack to reappear. Where one side of a crack has subsided, filling alone will leave a difference in level. Assess that profile separately when planning the repair.\u003c\/p\u003e\u003cp\u003eStore at 15–25°C for at least eight hours before use. Remove food products from the area during application and curing. Actual yield varies along a crack as its width and depth change.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes it need a primer?\u003c\/strong\u003e\u003cbr\u003eNo primer is required.
