Step 1
Clean the concrete wall with a power washing machine to blast off dirt , clay , honest-to-god rouge and all aerofoil contaminant . The concrete must be completely clean before it can accept a unexampled stucco coating , or the imperfections will show through the stucco .
Step 2
Inspect the wall surface to make indisputable it is completely firm and structurally sound . Do not enforce new stucco if you are not sure the wall can handle the added weightiness . If you find any holes or cracks larger than 1/8 - inch across , meet them in with concrete patch or epoxy . let all mending piece of work to dry before continuing .
Step 3
snub 3/8 - inch - thick wooden piece to match across the wall horizontally . Attach one of these piece to the very top of the paries and one to the very bottom , using masonry nail or piece of tail . These pieces will help insure you get a prostrate , grade program of stucco . If your wall is taller than 8 to 10 groundwork , install a wooden musical composition across the center as well to keep better track of your grade .
Step 4
Step 5
Mist the surface of the wall with a hosepipe to dampen , but not pluck , the paries . The concrete should be damp but not dripping for optimum stucco app .
Step 6
Put on twist gloves and goggles , as well as longsighted sleeve , to protect yourself from the caustic cementum . rain cats and dogs 1 three-dimensional foot of sand , one - third of a bag of cement and one - third of a bag of quicklime into a wheelbarrow . total water and commingle the contents until the cementum admixture is the consistency of pudding . Add the water gradually so you’re able to stop before the miscellany becomes too fluid .
Step 7
Load your cement mix onto a stonemason ’s hawk . Cut some of the mixture off , using a mason ’s trowel . work from the bottom of the rampart up , book the trowel at a 45 - degree slant to the wall and spread the stucco mixed bag onto the rampart . Spread it in flying , sweeping motion until the surface area is filled to the top of the wooden screeds you install early ; this will give you a 3/8 - in - thick root layer of stucco . examine not to fuss with the stucco once it ’s on the wall ; you will tear down it after . Continue to trowel until you have fulfill in the entire area between the wooden pieces .
Step 8
Step 9
dress a retentive , flat , consecutive piece of woodwind instrument or metallic element vertically against the wall at one ending . take the air across the country , sweep up the straightedge across the wooden screed pieces to flatten any bumps in the stucco theme pelage . Walk back to your start point as well to make a fully level surface .
Step 10
Inspect the stucco . Use the trowel to fill in any gaps you created with the level and then repeat the process until the nucleotide coat is completely flat . When everything is bland , detach the wooden pieces from the bulwark . practice the trowel to fill in the gaps exit by the wooden piece , scraping with the side of the trowel to keep the new stucco flat with the old . Once the entire stand coating is applied , provide the stucco to dry out until the refulgence on the surface is gone but the stucco is still relatively malleable ; the sentence this takes varies by climate .
Step 11
Step 12
Gently run a wooden or foam mason ’s float across the stucco surface in small circles or swirls . Working the stucco again after it has commence to dry out will reduce scissure and shrivel up as the base coat of stucco cures . set aside the base coat to dry overnight before you continue .
Step 13
desegregate up another batch of stucco . You do not have to vex about screed this time , as the last coat is only 1/8- to ¼-inch thick-skulled . Trowel the textile onto the surface , using the same methods as before , working in a thin , even layer , until the base coat is totally covered by the top coat .
Step 14
Roughen up the top coating of stucco with a stiff - bristle paintbrush . Work in convolution , lines or circles as you prefer to create a rough finishing to the stucco that matches your hope texture . Once you have the desired crudeness , allow the textile to dry out undisturbed overnight .
