Question DetailsAsked on 4/3/2016

can I replace a concrete sidewalk without replacing adjoining concrete steps? Will the concrete look cohesive?

Concrete steps leading to my house are in good shape, but the adjoining sidewalk needs replaced. Will it look weird to replace the sidewalks but keep the old steps? Do I have any options to keep the old steps but make them look newer or more uniform with a new sidewalk?

Do you have the same question? Follow this Question

I don't see why not - granted the new concrete will look "fresher" for a few years.

If you want matching appearance you could have them acid etch or sandblast the steps, then "brushcoat" them when they do the concrete work - basically brushing on a thin concrete mortar wash using the same finish tool as they do on the concrete (probably a broom finish for non-slip but maybe a hard-set troweling). It is important they use the same mix as the new concrete - a bit of left over concrete or cleanup droppings slightly wetted to make them workable and screened to remove the aggregate, then scrubbed across the steps to give a matching appearance. Then cured and sealed along with and at same time as the concrete.


If going with a smooth finish (floated and steel troweled say) so a sanded mortar brush coat would not finish up the same, though not recommended for sidewalks and certainly not in areas with ice/snow, then most readymix plants will provide a can or small bag of cement with the truckload (assuming readymix delivery) for this use on request. It is important to use the same cement as the pour to get the same color - different brands can come out different tone of gray to almost white.

Of course, if he is mixing the concrete himself on-site with a portable mixer than he will have the cement there to do this with.
