Lime Sand Mortar is the traditional and often preferred way of working. Mixed on site with cement and water, Lime Sand Mortars creamy consistency provides greater yields and bond strength.
Tarmac Lime Sand Mortars are factory produced Lime Sand Mortars for use in bricklaying, rendering, plastering or paving applications. Lime Sand Mortars are not intended to be used without cement except in some paving applications. The mixes must therefore be gauged and mixed with the appropriate type and quality of cement before use. Lime Sand Mortars are available from plants situated throughout mainland United Kingdom and are available in bulk or bagged form. Masonry mortars are available in coloured form, in which case controlled amounts of pigments are added and these are carefully selected and guaranteed by the pigment manufacturers against fading.
