Parexlanko 2842 Cast Cement 5kg, black powder for abrasion-resistant mortar

For masonry work on brick, stone or cement, the main decision is whether the mortar needs extra abrasion resistance or has to be used in cold conditions. Parexlanko 2842 Cast Cement is listed for both professional and amateur use.

It comes as a black powder in a 5kg pail. The product details identify PVA as the material and describe the finished mortar as highly abrasion-resistant.

The listing also mentions winter masonry between 0 and 5°C, resistance to extreme conditions and fast curing in cold weather down to -10°C. That makes the stated use more specific than a general-purpose masonry material.

What you’ll notice day to day

This is intended for use with masonry supports made from brick, stone or cement, and the details say it can be used in pure mortar or concrete. In practical terms, it is aimed at repair or building work where the mortar needs to stand up to abrasion, rather than a job where the only requirement is to fill a joint or bed masonry.

For example, someone working on a masonry project during colder weather may find the stated winter-use range relevant, while the abrasion-resistant mortar claim may matter where the finished surface will experience wear. The listing does not explain how much product to use per mix or give a coverage figure, so those details cannot be used to plan quantities from this information alone.

It’s a good fit if the project involves brick, stone or cement and calls for an abrasion-resistant mortar, including the stated cold-weather use. A standard mortar may be the simpler choice where abrasion resistance and winter working are not requirements. It’s not for you if the work is outside the listed masonry supports or you need a product with documented mixing ratios or coverage figures.

What to know

The product is supplied as one 5kg quantity in a pail and is described as a low-viscosity powder. Its listed colour is black. The stated applications include both amateur and professional use, but the listing does not provide a mixing method, setting time for ordinary conditions, or guidance on how to prepare different substrates. Those points matter when estimating a job or matching a material to a particular repair.

The cold-weather information has two parts: masonry use at 0 to 5°C and fast curing in cold weather down to -10°C. These are the conditions stated in the product details, they should not be read as a complete application guide. Follow the supplied product instructions for preparation and handling, particularly if working at low temperatures.

How to use it

The listed uses are as an ingredient in pure mortar or concrete, for brick, stone or cement supports. The product is not described as a ready-to-apply paste: it is supplied in powder form. Plan the mix around the instructions provided with the product, as no proportions or application steps are included in the available details. For a small repair, the 5kg pack gives a defined quantity to work with, for a larger job, the listing does not state how much area that quantity will cover.

Practical questions

What supports is it listed for? The details name brick, stone and cement masonry supports.

Can it be used in cold weather? The listing specifies winter masonry between 0 and 5°C and also states fast curing in cold weather down to -10°C. It does not provide a full temperature-based application guide.

Is it supplied ready to use? No ready-to-apply form is stated. It is listed as a powder for use in pure mortar or concrete, so use the product instructions for mixing.

Is it worth it?

The case for choosing Parexlanko 2842 is clearest when abrasion resistance or the stated cold-weather use is relevant to the masonry job. Its named supports and mortar or concrete applications give a useful starting point, while the 5kg pack makes the quantity explicit. If you only need an ordinary mix and do not need those characteristics, a more basic masonry product may suit the job just as well. Check the supplied instructions for mix proportions and handling before relying on it for a specific repair.
