Product Information

Aside from the techniques we have run through above for extracting sand from the original mortar, which is very effective by the way, you can also undertake some local research. Concrete mix coloured grey due to colour of the cement used What Other Factors Affect Mortar Colour? ASTM C 1329 on mortar cement is a sister product to C 91. The difference is that mortars made with mortar cements must have certain minimum bond strengths because these materials are intended for use in more structurally demanding applications. Cement types are the same as in C 91: N, S, and M. While it is not disallowed, there does not seem to be much demand in the marketplace for white mortar cement.

Ask if you can have a small sample of each so that you can run some colour matching experiments (more on this later). Its boring and time consuming, but if you do not want your repairs to stand out a mile off, it has to be done! With your sample to hand place them on an old scrap piece of wood. Using a similar scrap piece of wood, place this on top and use it to grind the mortar down. Essentially you have to repeat the above process e.g. creating several different mixes but adding the required dye or tone colour in different quantities until you have a decent colour match. I have tried adding in a little Snowcrete and it does soften the colour a bit to allow some sandy tones but it's still not proper sand coloured.If you have gotten to this point, done a vast array of test mixes, tried every dye, tone and tint you can find and still cannot get a match there is yet still more hope! However, if the mortar is very light in colour then this suggests that either a white cement (aka Snowcrete) or lime has been used. Once the colour is matched as closely as possible, the tint is then brushed onto the mortar after it has been applied and fully cured where it then dyes and colours it. Another factor that can alter the colour of mortar is whether lime was used in the original mix. As lime is naturally light in colour and is often used in place of cement in some mixes, mortar created using lime can look very light in colour and in some cases be nearly white. White portland cement has essentially the same properties as gray cement, except for color. It is readily available throughout North America.

Grey concrete is most often used for structural building, as it is more cost-effective than selected white or light-coloured variants. While white concrete offers the same level of strength, it will be commonly used for more decorative exterior elements and finishes, as well as in interiors, such as finishes for beautiful kitchen countertops. White concrete also has the added benefit of remaining white even as the structure ages. How Long Does White Cement Take to Dry? I wonder if I need a different cement, to include lime not snowcrete, a different colour sand? If anyone can help I'd be grateful.White cement is naturally waterproof, and will not require any additional waterproofing measures when used in a building. Its waterproof nature, as well as its ability to withstand much higher temperatures than other types of cement (thanks to its reflective white finish), make white cement a brilliantly versatile and dependable building material that can withstand the harsher elements when used on exteriors and the wear and tear of interior living. Is White Cement Eco-Friendly? You may have heard that white cement is environmentally friendly – and this is true. From a production standpoint, white cement requires less energy to produce than grey cement, and the manufacturing process is much cleaner. The main ingredient in white cement is limestone, which can be easily sourced across the world. If it helps, I am looking for the sandy colour that this chap was able to get in his "this is how it turned out" picture (but funnily enough he wanted more grey!): You now need to drain off your sand solution. Using a container with a fairly large mouth that can again be sealed, stretch an old pair of tights over the mouth and secure it with a strong elastic band.

Some mortars are artificially coloured with a cement dye or mortar tone. This makes the permutations endless as you not only have to think about the sand and cement that was used but also what dye was used!When it comes to strength both mixes will perform to a similar high level, and much of the discussion around differences in strength is still speculative, differing from brand to brand. Both will only achieve their full strength and durability potential when mixed into concrete. NOTE: For larger surfaces, you can use more bags of concrete, more dye, and more water; you just have to be sure that you've done the correct calculations to multiply your needed materials. For Resurfacing

CSA A 3001 is the Canadian Standards Association standard for Cementitious Materials for Use in Concrete. The portland cement nomenclature is the same as C 1157. The blended cement nomenclature builds off those designations. As with the ASTM specifications, white cement could be specified under the portland cement designation, but would not likely be specified under the blended cement specifications. See CSA Groupfor more information. So as you can see, not only does the colour and type of the sand that used in a mortar mix affect its colour but so does the cement and the presence of lime if it has been used. How do I Know What Colour Sand was Used in the Original Mortar? To get a multidimensional finish, mix the concrete with one uniform color, using a complementary color to add lashes to the mix. The concrete will dry with the second color mixed randomly, providing an interesting effect.Just be sure and always create a test batch first. Different cement brands and mixtures are formulated differently and may react with pigments uniquely. Testing is the best way to determine how your DIY cement dye will turn out in your final project. Although I have only tested white, many other pigments are mineral-based and should reliably add drama and color to cement. Thanks for Reading!!! Essentially, this is down to the colour and type of sand that’s used. There are many types of sand and each type will produce a different colour mortar when mixed with cement. Without colouring, can anyone recommend how to get a strong pointing mix that is a sandy colour? The original pointing was strong cement so we are planning on a like for like. From concrete plastisicers and mortar water proofers to cement accelerators, retarders, dyes and everything in between, we’ve got it at Selco. The next most significant component of a mortar mix is the cement. Unless the existing mortar is particularly light in colour (light cream or white colour), in most cases a standard cement will have been used e.g. grey cement.
