1.- What are some of the advantages and disadvantages of stucco relative to other economical cladding options?

A.-Stucco is durable, low maintenance, weather resistant, insect proof, impact and noise resistant, it performs well in a variety of climatic conditions. Stucco also provides up to one-hour fire resistance, a feature that sets it apart from other economical cladding materials. Stucco can be configured into practically any shape or form desired: arches, ornamentation, rounded corners, special designs, No other material offers this kind of design latitude, for examples visit our Image Gallery click on stucco detail trims, it can also be applied in many textures, finishes and colors to provide environmental harmony as well as aesthetic impact. If stucco has a disadvantage, it is that on the front end it can be more time consuming to install. But over the long-term, stucco provides far greater value than comparable economic cladding materials.  

   2.- Can you use Exterior Stucco in an interior application?

A.-Yes, stucco color coat may be successfully applied to a portland cement base substrate in an interior application. However exterior stucco color coat will not stick to drywall or other non-cementicious surfaces unless an adhesive is applied to the surface prior to stucco application. For better results on stucco or Stone veneer interior installations wooden walls  are recommended together with a water resistant barrier, lath metal mesh and scratch coat to assure  bondage and  long lasting stucco applications.

   3.- Can I paint stucco to get the color I want?

A.-Stucco can be painted. Portland cement-based paints are very compatible with stucco because they are made of the same material. These paints should be scrubbed into the surface and fully cured. Alternatively, you could consider a colored stucco finish. These finish coats are often made with white cement and pigments, providing the widest range of colors. It is possible to paint with other types of paint, though these are usually not as long lasting as cement-based paint. Acrylic paints are long lasting and durable but change the permeability of the stucco (make it non-breathable) which in some climates may have adverse effects on the long-term performance of the system. Rene  Munoz Plastering also  offer stucco Paint  services.

   4.-How long does stucco last on a building?

A.-Properly applied and maintained stucco, is as durable as any commonly used cladding material. Its hard surface resists abrasion and can take a lot of physical abuse. It stands up to all sorts of climates, from cold to hot and wet to dry. Many older homes built in the early 1900s have had very little maintenance and remain in good shape today.

   5. What is the difference between regular sand-cement stucco and acrylic stucco?

A.-There are two principle types of stucco finish, sand-cement and acrylic. Both incorporate the same traditional sand-cement basecoat, but the latter contains a flexible acrylic-based top layer. Acrylic stucco is more time consuming to apply, but is considered to be more water-resistant when water resistant barrier has been properly installed the Acrylic finish downside is that it has a limited range of texture but comes in almost any color imaginable. Cement stucco has an unlimited variety of textures but is limited in color.

    6.- What causes my stucco to fall off at the bottom of the wall?

A.-This is usually caused by extended exposure to moisture, which will eventually deteriorate the stucco, water sitting at the base of the wall and traveling up the wall in a wicking action, lack of weep screed at the bottom of stucco walls, Sprinklers hitting the wall, improper drainage (water draining toward the wall).

   7.-What  are the common signs of Water  Damage?

Apparent water seepage on the exterior of the house, specially at  the bottom of the  windows, where lower part  of  the roof  is  united  in the  middle of  YOUR stucco wall( vertical)  as well as shoulders of the  chimney. Stucco  or  Dryvit®  blistering on  walls  is  a  common sign  of  an  improper installation or deterioration of  your  property.

   8.-Where should   I inspect my house?

A.-The  principal  targets  for  an  inspection will be  at the bottom  of the windows, where the lower part roof is  united  with the stucco wall, another  place will  be  in  the bottom  of  your  house such   as decks, gardens, pavers steps and  patios that  normally   are  installed  over grade.

   9.- Should  I contact  an inspector?

A.-An inspector is always recommendable, they will perform a visual inspection of the property and provide a detailed information on stucco cladding systems and their accessories. Is always good to find a certificated stucco inspector to help you point out areas that can be problematic and cause a need for stucco repair,they will use moisture meter readings for a more accurate diagnostic, on top of that they will provide a detailed written report of any stucco damage suspected along with recommendations he may make for maintenance of your stucco home or stucco repairs that may be necessary to ensure long lasting cladding.

   10.-If there is a problem with the stucco on my home, what will be required to correct it?

A.-A building permit is required for stucco repairs. The building code requires that all wood with mold or rot be removed and repaired. Areas that do not show signs of leaks, mold, rot or deterioration may remain. Proper installation of doors, windows, flashing and any other wall penetrations must be in perfect conditions. Proper Weep Screed installation, Kick-Out Flashing diverter, Expansion Joints  should be  installed where needed,  Drip Cap  Flashing  should  be installed over the head casing of each  window  and door, Window Protecto Wrap (window flashing) should  be  installed over window flanges and on top  of window and door drip cap flashing, J Channel or EZ Bead should be installed around  windows, doors  and  any  other  places  where stucco is united with  other surfaces leaving  a gap  for  caulk , J Channel should  be  installed  1”1/2  above roof shingles, on wooden  walls double layer  of  a water resistant barrier should be applied followed  by self furring installation,2 coats of Portland cement should  be applied to  the walls finally either  regular sand-cement stucco, acrylic finish (Dryvit®),brick or  stone is installed.

   11.-What is an expansion joint and the proper spacing for it in stucco applications?

A.-An expansion joint is an assembly designed to safely absorb the contraction and  vibration of Portland cement plaster (stucco). The proper use of expansion in stucco systems will depend on a number of variables, including: the type of construction materials to which the stucco will be applied; the orientation of the construction vertical (walls) or horizontal (ceilings); and whether the surface is curved or angular.

   12.-What is Kick-out Flashing?

A.-A critical location where moisture entry can do considerable damage is where a lower roof cornice stops in the middle of a stucco wall (vertical).  Kick-outs should be fabricated with watertight seems and be big and broad enough to handle water run-off from a variety of roof pitches. kick-out flashing should be installed under shingles and behind existing roof flashing.  For better results kick-out flashing should be installed by the roofer as the shingles are being laid up with a  layer of a resistive barrier behind both, roof flashing and kick-out flashing. It will help keep water from running down the new stucco wall, add life to the original appearance of your stucco as well as protecting the existing frame from constant moisture. See our Remediations page under Image Gallery to find out the damage caused by a missing kick-out flashing diverter or it’s wrong installation.

   13.- What  is  Weep Screed and  where is  installed?

A.-Weep Screed Extended Leg is used to provide a weep mechanism as part of the drainage system is required at the bottom of all framed walls. This helps to protect the edge of the sheathing from moisture and insect damage.  MINUM 4” above finish grade. And two inches above paved areas. The 3-1/2" nailing flange serves as a flashing when water resistant barrier is installed over the flange.

   14.-What  is EZ Bead and can I  use  a regular  J channel  instead?

A.-Water leaks occur all too frequently due to inappropriate and ineffective flashing systems. E-Z Bead™, eliminates  the risk of moisture penetration. The flexible build  in strip give you an straight and uniform  spacing around the  window, doors and any  other  point where stucco  meets  a dissimilar material. With  this unique  piece we will achieve protection  and  a clean  look for YOUR property. With regular J channel application backer road should  be  applied before caulking a gap.

   15.- What  is  a Drip Cap Flashing?

A.-Is  a  pre bent metal, comes in  a variety of  colors depending on your needs, drip cap flashing should  be  installed over the head casing of all doors and windows. A Drip Cap flashing will prevent water from penetrating the door or window frame. It also should be installed on deck header board if this is the case, on curved windows flexible Drip Cap Should be installed.

   16.- What is window flashing tape?

Water and Moisture from wind blown rain, leaks and condensation can accumulate in window openings causing black mold, wood rot and structural damage the window, here is when window flashing comes handy it is an sticky tape designed to adhere to vinyl in our case window’s flange but is also used on plywood, OSB, foam, metal, aluminum, and masonry providing maximum protection from moisture intrusion. Combines advanced peel-and-stick adhesive it forms a permanent waterproofing air/vapor seal around doors and windows that prevents air and moisture leaks.
