It is used for fence posts, gate posts, rotary washing lines, signposts, pergola and decking posts, and any job where a post needs to be fixed quickly and securely.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe appeal of a post mix is how little it asks of you. The cement and aggregate come pre-blended in the correct proportions, so there is no mixing board, barrow, or measuring involved — the dry mix is poured straight into the hole around the post and water added on top, or added to water in the hole depending on the manufacturer's instructions. It sets within minutes rather than hours, which means a post can be held plumb by hand for a short time and then left, instead of needing propping and bracing overnight before the next one can go in. On a fence run of a dozen posts, that difference decides whether the job takes a day or a weekend.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSet the post in a hole roughly three times the width of the post, with around a quarter to a third of the post length below ground, and check it for plumb in both directions before the mix goes off, as there is very little time to adjust afterwards. Finish the top of the concrete slightly above ground level and slope it away from the post so rainwater runs off rather than sitting against the timber. One 20kg bag is typically enough for one standard fence post, though gate posts and larger sections will need more.\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003eSpecification:\u003cbutton type=\"button\" class=\"btn btn-link lnkChangeSection\"\u003e\u003c\/button\u003e\n\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"accordion\" class=\"product-page__accordian\"\u003e\n\u003cdiv id=\"collapse_specs\" class=\"collapse show\"\u003e\n\u003cdiv class=\"product-page__spec-table-wrapper\"\u003e\n\u003ctable class=\"product-page__spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eWhitestar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Home \u0026 Trade","offers":[{"title":"Default Title","offer_id":55403661394247,"sku":"WHITE002","price":5.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/7759\/6999\/files\/WhitestarPostfix20kg.jpg?v=1791879079"},{"product_id":"whitestar-cement-42-5n-in-plastic-25kg","title":"Whitestar Cement 42.5N in Plastic 25kg","description":"\u003cdiv class=\"product-page__body__info-wrapper\"\u003e\n\u003cdiv class=\"text-block small-text color-light-gray\"\u003e\n\u003ch5\u003eProduct Description:\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003eWhitestar General Purpose Cement is a Portland limestone cement supplied in a 25kg plastic bag, manufactured to EN 197-1 and achieving strength class 42.5N. It is suitable for concrete, mortar, render, and screed, and is used across bricklaying and blockwork, foundations and slabs, garden walls, paving bedding, rendering, and general repair work on both domestic and commercial projects.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe 42.5N strength class is the general-purpose standard, and it indicates the compressive strength the cement reaches at 28 days. Manufactured to EN 197-1 from carefully selected raw materials with quality control at each stage, it gives consistent performance from bag to bag, so mixes made weeks apart cure to the same strength and colour — which shows in a finished wall or slab far more than most people expect.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe plastic bag is a practical improvement on paper. It keeps the cement dry in storage and on site, tolerates a rain shower and a damp floor without the contents setting solid, and allows a part-used bag to be resealed and kept for later rather than wasted. For concrete, a common general-purpose mix is one part cement to two parts sharp sand and four parts aggregate; for bricklaying mortar, around one part cement to four or five parts building sand, with lime or plasticiser added for workability. Mix with clean water to a workable consistency and use within the working time.\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003eSpecification:\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"accordion\" class=\"product-page__accordian\"\u003e\n\u003cdiv id=\"collapse_specs\" class=\"collapse show\"\u003e\n\u003cdiv class=\"product-page__spec-table-wrapper\"\u003e\n\u003ctable class=\"product-page__spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eWhitestar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Home \u0026 Trade","offers":[{"title":"Default Title","offer_id":55403661656391,"sku":"WHITE001","price":6.85,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/7759\/6999\/files\/WhitestarCement42.5NinPlastic25kg_240567f0-ab24-44ff-b7fe-a154acd2bdd5.jpg?v=1791879080"},{"product_id":"blue-circle-quality-assured-mortar-mix-20kg","title":"Blue Circle Quality Assured Mortar Mix 20kg","description":"\u003cdiv class=\"product-page__body__info-wrapper\"\u003e\n\u003cdiv class=\"text-block small-text color-light-gray\"\u003e\n\u003ch5\u003eProduct Description:\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003eBlue Circle Quality Assured Mortar Mix is a pre-blended general-purpose mortar of cement, hydrated lime, and specially graded sand, supplied in a 20kg weatherproof bag. Suitable for most brick and block applications, it is used for building garden and boundary walls, laying bricks and blocks on extensions and outbuildings, repointing, bedding copings and sills, and general masonry repair across both interior and exterior work.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe pre-blended format is what makes this mix so convenient. The cement, lime, and sand are proportioned consistently in every bag, so there is no need to buy, store, and measure separate materials, and every batch mixes to the same strength and colour. That consistency matters on smaller jobs in particular, where hand-mixing a few buckets at a time from loose materials tends to produce variation from one batch to the next, which shows in the finished joints.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe hydrated lime and plasticiser give the mix a smooth, buttery consistency that spreads easily on the trowel, holds well on the vertical face of a brick, and stays workable for longer, making it more forgiving for DIY bricklayers as well as quick to use for trades. Lime also gives the cured mortar a degree of flexibility, helping it tolerate small movements in the wall without cracking. Simply add clean water and mix to a workable consistency. The weatherproof plastic bag keeps the contents dry in storage and on site, so part-used bags can be resealed and kept for later.\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003eSpecification:\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"accordion\" class=\"product-page__accordian\"\u003e\n\u003cdiv id=\"collapse_specs\" class=\"collapse show\"\u003e\n\u003cdiv class=\"product-page__spec-table-wrapper\"\u003e\n\u003ctable class=\"product-page__spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"product-page__spec-table__heading\"\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBlue Circle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Home \u0026 Trade","offers":[{"title":"Default Title","offer_id":55403702485319,"sku":"MOR001","price":10.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/7759\/6999\/files\/Blue_Circle_Quality_Assured_Mortar_Mix_20kg.jpg?v=1791879258"}],"url":"https:\/\/homeandtrade.co.uk\/collections\/cement-products.oembed","provider":"Home \u0026 Trade","version":"1.0","type":"link"}
