{"product_id":"watco-concrex-fine-filler","title":"Watco Concrex Fine Filler","description":"\u003cp\u003eWatco Concrex Fine Filler is a two-part epoxy paste for small concrete repairs before painting. Use it to fill chips, scratches, bolt holes and surface blemishes that can become more noticeable under a new floor coating, particularly a gloss finish.\u003c\/p\u003e\u003cp\u003eThe components mix into a grey repair paste that presses easily into minor defects and can be feather-edged for a smooth transition. It suits floors and vertical surfaces, indoors or outside, and needs no primer. Mix small quantities as you work through scattered damage, rather than opening a large batch for a handful of shallow repairs.\u003c\/p\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRemove dust, grease, oil and contamination. The surface must be sound rather than loose or friable. Clean exposed steel reinforcement back to bright metal. Slight surface dampness is acceptable, but do not apply to wet surfaces.\u003c\/p\u003e\u003cp\u003eIdentify chips and scratches before coating and work the filler into each defect.

Mix on a suitable board until the paste is an even grey, with no streaks. Wear the gloves supplied and prepare only what you can apply within the working life.\u003c\/p\u003e\u003cp\u003ePress into the damage with the plastic spreader and smooth flush. Wiping the scraper with a cloth dampened with white spirit makes finishing easier. Clean spills and tools before the filler cures. Once hardened, the repair can be painted with a suitable Watco coating or left as a wearing surface.\u003c\/p\u003e\u003ch3\u003eLimitations\u003c\/h3\u003e\u003cp\u003eCure times increase in cooler conditions: at 10°C, allow approximately 2 hours before overpainting, 6 hours before foot traffic and 24 hours before heavy traffic. Full hardness takes around seven days at this temperature. Plan the coating and reopening schedule accordingly.\u003c\/p\u003e\u003cp\u003eStore unopened packs at 10–30°C, protect from freezing and use within the 12-month shelf life. Remove food products during application and curing. Yield is given as mixed volume because coverage depends on the number, size and depth of the defects.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs a primer needed?\u003c\/strong\u003e\u003cbr\u003eNo primer is required. Apply to a clean, sound substrate; slight dampness is acceptable, but the surface must not be wet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I mix only part of the pack?\u003c\/strong\u003e\u003cbr\u003eYes. Mix equal portions of resin and curing agent by weight or volume until uniformly grey. Prepare small amounts that can be applied within the working life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much filler does one pack make?\u003c\/strong\u003e\u003cbr\u003eThe 1.5kg twin pack produces approximately 1 litre of mixed filler. Area coverage depends on the depth and shape of the defects.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow soon can I paint the repair?\u003c\/strong\u003e\u003cbr\u003eAllow approximately 1 hour at 20°C or 2 hours at 10°C before overpainting. These are initial-set times; heavy traffic and full hardness require longer.\u003c\/p\u003e\u003ch3\u003eData Sheets\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/9017\/6596\/files\/watco-batch7-fine-filler-datasheet-14.pdf?v=1793982426\" target=\"_blank\" rel=\"noopener\"\u003eTechnical Data Sheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/9017\/6596\/files\/watco-batch7-fine-filler-datasheet-10.pdf?v=1793982426\" target=\"_blank\" rel=\"noopener\"\u003eSafety Data Sheet - Curing Agent (GB)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/9017\/6596\/files\/watco-batch7-fine-filler-datasheet-11.pdf?v=1793982426\" target=\"_blank\" rel=\"noopener\"\u003eSafety Data Sheet - Resin (GB)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/9017\/6596\/files\/watco-batch7-fine-filler-datasheet-12.pdf?v=1793982426\" target=\"_blank\" rel=\"noopener\"\u003eSafety Data Sheet - Curing Agent (GBNI)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/9017\/6596\/files\/watco-batch7-fine-filler-datasheet-13.pdf?v=1793982426\" target=\"_blank\" rel=\"noopener\"\u003eSafety Data Sheet - Resin (GBNI)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watco","offers":[{"title":"1.5kg","offer_id":58185372172628,"sku":"CXFF","price":60.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/9017\/6596\/files\/watco-batch7-fine-filler-1.jpg?v=1793982462","url":"https:\/\/andrewscoatings.co.uk\/products\/watco-concrex-fine-filler","provider":"Andrews Coatings Ltd","version":"1.0","type":"link"}
