Seal: apply one or more coats diluted with 5 parts water at 0.62 litres\/m² and allow to dry for no more than 36 hours. A sheen on the surface indicates adequate sealing; very porous substrates may need two or more coats. Prime: apply one coat diluted with 3 parts water at 0.71 litres\/m², brushed well in. Lay RonaScreed Self Smooth Screed while the primer is tacky, typically 2–4 hours after application at 20°C and 65% RH. Check the manufacturer's datasheet before use.\u003c\/p\u003e\n\u003ch3\u003eCoverage\u003c\/h3\u003e\n\u003cp\u003eDivide the floor area by 3.5 to get the litres of primer needed for one sealing coat and one priming coat (e.g. 1000 m² ÷ 3.5 = 286 litres). On that basis a 5 litre unit seals and primes approx. 17.5 m² and a 25 litre unit approx. 87.5 m².\u003c\/p\u003e","brand":"RONACRETE","offers":[{"title":"5L","offer_id":55608058806611,"sku":"RONA-SSP-5L","price":63.84,"currency_code":"GBP","in_stock":true},{"title":"25L","offer_id":55608058839379,"sku":"RONA-SSP-25L","price":236.04,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/6720\/9043\/files\/ronascreed-self-smooth-primer.jpg?v=1793696876","url":"https:\/\/shop.screedworks.co.uk\/products\/ronascreed-self-smooth-primer-5l-25l","provider":"Screed Works Shop","version":"1.0","type":"link"}
