Can Grout Be Used To Repair Stuco

Q: My 42-year-old driveway is in pretty good shape other than some unsightly cracks that have been patched. Could I get an even appearance to the entire surface past applying a thin layer of colored thinset grout? Would it concur up to vehicular traffic? If so, how would I apply information technology to make it look nice? If not, do you accept other ideas?

A: You lot tin transform your driveway using colored thinset grout if you choose, but I'd recommend a slightly different textile that will provide more durability.

This is a exercise-information technology-yourself projection if you lot tin muster the help of three friends for half a 24-hour interval. The total cost: less than $500 — including pizza and beverages for your crew.

To repair the cracks, grind them out using a pressure level washer to remove every bit much debris equally possible. Open the cracks to the slab'southward full depth.

Employ a concrete epoxy fissure-repair product to bond the broken slabs. If you lot skip this step, the cracks will show through the new overlay. The repair might have one or 2 days. The epoxy yous choose will tell y'all how wide, clean and deep the epoxy must penetrate to get a lasting repair.

When prepare to resurface the driveway, use a layer of cement stucco to it — as sparse equally a quarter-inch. This stucco is like to thinset grout, just the sand particles are much larger. Thinset usually contains a fine silica sand. To withstand vehicular traffic, you need the larger sand particles found in coarse or medium sand. Traditional sand usually contains small-scale rock particles that are dissimilar hues, which will provide surface color.

To make the stucco, blend one role Portland cement and three parts sand. To achieve the desired colour, just add together dry out milk shake pigments fabricated for brick mortar or stamped concrete applications. These ingredients are sold at edifice supply stores that cater to bricklayers and stonemasons.

Make up a test batch of the stucco, pouring information technology on a plastic sheet in the garage and waiting 30 to 45 days to see what color it turns out to be. The last affair you want is to practice all this work and not exist happy with the colour.

To get the new stucco to bond permanently to the existing concrete, apply a thin coat of cement paint to the driveway just earlier pouring the stucco. Make cement pigment by mixing pure Portland cement with h2o to the consistency of regular paint.

Just before applying the cement pigment, spritz the driveway with water (just damp, not wet). Roll the cement pigment on the driveway just earlier y'all pour on the stucco mix; don't permit the cement paint to dry. If possible, work on a libation, overcast day; sunny, windy days aren't suited for this job.

Use a magnesium float to terminate the stucco. For a linear pattern, yous tin can also utilise a broom finish, only it must be at the right time: Apply the strokes too early on and you end up with a mess; wait besides long and the stucco gets too hard for the bristles to leave a good impression.

For even coloring in each batch of stucco, measure ingredients precisely and add the aforementioned amount of h2o each time.
