I had a lady call me the other day wanting to know the correct way to fasten her hose holder to the outside of her EIFS home. She could not get it to stay on the wall. This is actually a very good question, because there is a very specific way to install things to the outside of this cladding (Exterior Insulation and Finish System also known as Dryvit ® or synthetic stucco) whether it is a hose holder or a down spout for a gutter. First of all you are going to have to use a screw long enough to go through the system. Typically you will have between 1 1/2 inches to 4 inches to go through. You can tell how thick the material is by checking the bottom. The Synthetic Stucco will stick out from the wall and you can measure it there. Use a 3 or 4 inch screw and a 3/8 inch piece of PCV pipe. Drill a hole with a 3/8’s drill bit into the cladding where you want the screw to go. Stick the PCV pipe in the hole and make a mark where it is flush with the wall. Remove the PCV pipe, and cut it on the inside of the line as not to have the pipe stick out past the wall, but remain flush with the Synthetic Stucco finish. Apply adhesive (PL-Premium®, found at your local hardware store) to the outside of the PCV pipe and insert it in the hole you just drilled. The PCV pipe should sit all the way back to the substrate (OSB), and come out flush with the stucco surface. It is very important that the pipe is a tight fit, and the adhesive should be around the end that is outward at the Exterior Insulation and Finish System surface to make a good seal. Wipe any excess adhesive away with a damp cloth before it drys. Now, fill the pipe about half way with silicone caulk, and screw your hose to the wall using the holes you just made. When you screw the screw into the pipe excess caulk will come out the PVC pipe again use your damp cloth to remove any excess caulk that gets on the stucco’s finish coat or top coat. That is the old school way of doing it, and of course nowadays you have a fancy new way of doing it, and that would be a Corrosion Resistant Fastener and Sleeve Set. Myself I still use the PVC pipe and it works great, and like I always say if it ain’t broke don’t fix it. If I was doing a large house or building that had down spouts I would however use the Corrosion Resistant Fastener and Sleeve Set’s just to save a ton of time.
Well, there you go, that is the correct way of attaching things to your Synthetic Stucco cladding.
The last thing you want to do is just run screws into your this cladding system, as it will create penetrations that water can enter the system and cause problems down the road.

DIY EIFS – Do It Yourself EIFS Repairs
The other day a came across an EIFS house that I could see every piece of foam on. I have seen some EIFS applications where in the right sunlight you could see a few pieces of foam, but this was the worst you could literally see every piece of foam. The home owner naturally asked me how this could have happened. Apparently the contractor told him that is just how it looks. I can tell you that, that is not true. There is a few reasons that could have happened and in this case it was probably all of the above. If the foam is not rasped or rasped correctly you will be able to see the foam pieces after the job is done. Also, the adhesive used to adhere the foam to the wall can get in between the pieces, and cause gaps. The gaps will dry at a different rate due to moisture and heat flow, and that will cause them to be seen. I have purchased foam that was not all exactly the same thickness, which if not rasped down will cause the pieces to be seen, but this is very rare I have only seen this a couple times in my 23 years in the industry.
In the case I just seen I am sure they did not rasp the foam at all, and when sticking the foam they did not make sure the pieces where applied tightly together, which caused the finished product to look like that. To fix the wall it now needs to coated with two layers of base coat. The first layer to fill in all the seams to even them out. The second layer is a complete coat over the entire wall to blend everything together. This process to repair the wall takes a highly skilled plasterer. Short of that you would have to re-stick the entire wall, essentially redoing the wall over the existing EIFS.

First of all, let me thank you for stopping by EIFS Repair and checking our new EIFS Repair Training program. As we always do here at EIFS Repair we listen, and respond. We have had some feedback on the EIFS Repair Kits and it was that businesses wanted training for their employees, so we are now introducing the all new EIFS Repair Training program. The training is done in a couple different ways. One is that we do the training here in our facility in Michigan, and the other is that customer fly’s one of our EIFS professionals out, and they do the training on their site.
The EIFS Repair Training will be done by an EIFS expert with at least 20 years hands-on experience in the EIFS industry. All of our trainers are a master plasterer, which means they have been journeymen plasterers for over ten years. The training will cover everything to look for when doing EIFS Repairs, the EIFS process, and proper installation of the EIFS product. We will cover the most common problems that you will find, and those little things that EIFS contractors just hate to do. The training will teach you how to spot them, and fix them without breaking the bank.
The training will begin with about an hour of explanation of EIFS, and the EIFS process. Then we will talk about the EIFS Repair Kit, how it works, and the tools involved. The EIFS Repair Training, for the most part, will be hands-on training, with a few mock ups of some typical repairs you would see in the field. With these pre-made damaged EIFS samples the trainee has the opportunity to do an EIFS repair for themselves to get a real feel of the EIFS Repair process. Believe it or not, the EIFS Repair process is more of an art than anything else. We believe that there is no better way to learn how to do a good quality EIFS repair than to have one of our experts walk you through it in our new EIFS Repair Training program. The amount of information and specialized training, you could not learn anywhere else, is second to none when you spend the day with one of your EIFS trainers.
The EIFS Repair Training Program comes with a helpful guide you can leave with your employees to refer back to when doing the EIFS repairs in the field. This helpful guide has a overview of the EIFS process step-by-step and the common EIFS Repair things to look for and how to address them.
The EIFS Repair Training Program at a glance
The EIFS Repair Training is a one day class, and it is scheduled for 5 hours. Typically we start the classes at 11 am and they go through to about 5 pm with a lunch break at 1pm. The time schedule is completely flexible and can be tailor around your company needs. Fill out our EIFS Repair Training Form and please include your estimated training date, your company name and a working number for us to get back to you.
Our EIFS Repair Training is a flat rate of $800.00. If you attend our EIFS Repair Training here in Michigan that would be your total cost, but if you are out of State you would pay to fly our training to you. The trainer would be flown out the day before the training to have time to setup. The trainer would not be flying with our mockup EIFS samples for the hands on part of the program so the trainer would build the mockups the day before at your facility. Our out of State customers have an extra material cost of $200.00, the extra cost of a round trip air flight for our trainer, and a one night stay at a local hotel. The bottom line for our out of State customers is $1,100.00 plus a round trip flight from DTW.
The EIFS Training is for all Synthetic Stucco, Dryvit, Senergy Sto, Master Wall, and Parex.
The Fiberglass Mesh keeps the EIFS cement from cracking. The EIFS cement coat is only 1/8 inch thick and would crack without the fiberglass mesh. The mesh gives the EIFS System strength and with it being fiberglass it has a heck of a lot of flexibility as well. When applying the fiberglass mesh you must overlap the mesh at least 2 inches and the entire foam has to be covered with mesh. Any places that are not covered with mesh are going to crack and spider over time. The Fiberglas mesh is also used before the foam is applied as a back wrap for all the windows and doors. A 9 inch ripe of fiberglass mesh is stapled round each window and door with the mesh face out toward the window or door. Then the foam is fastened over the mesh and the over hanging 7 inches of mesh is wrapped back up onto the foam with the base coat. This method is called backing wrapping. Back wrapping is very important to help water and moisture from penetrating the EIFS System.

The EIFS Repair Kit includes a trowel which is your application tools. The shape of the trowel is perfect for scoping out the cement mix and gives you a great way to spread the cement smoothly onto the wall. The EIFS cement mix is made to be applied very thin, approx. 1/8″ thick with little waves or bumps in the cement coat. The cement coat should be applied with great detail to perfection as the finish coat will only look as good as the cement coat under it. If you can not get it smooth you can let you best work dry and come back and sand it smooth. The best think to sand the cement coat with is floor sand paper. You can find floor sand paper at your local home improvement store. Another thing to keep in mind is that your cement will dry up after time and become very hard to work with. The dry time has a lot to do with the temperature. If you are working on a cloudy 60 degree day you may have about 45 minutes to work with your cement before it begins to show signs of drying up. But if you are out on a sunny 90 degree day you may only have about 10 minutes to complete your project. Keep in mind that the EIFS material should never be applied in weather that is below 40 degrees.

The stir paddle is included in the EIFS repair kit because it is a perfect way to mix the cement. It is very important that the cement is mixed throughout and the paddle will ensure that it is. Make sure that all the dry mix is spun up into the cement mix. And when you add the AR glass to the cement mix make sure you pour the glass in slowly while spinning the mix. The glass should only be spun into the cement mix for about 45 seconds. That is the best period of time to ensure the glass fibers have intermixed with the cement.
EIFS Repair Tip Of The Day for 3-22-2011
Getting an EIFS patch to look right. How to repair EIFS
One of the keys to getting an EIFS patch to look right is to make sure the patch is feathered in correctly. The patch will stick out from the wall slightly more than the rest of the wall which may not seem like a big deal, but when the sun shines on it the patch will stick out like a sore thumb. The key to preventing this from happening is to use a paint brush to feather your brown mud out past the actual patched area a few inches in all directions. Then when the finish is run the same thing is done. The finish should be feathered a few inches into the existing finish then lightly hit with the float to knock down any high spots. It is important to get a real good texture and color match for best results.
The only other way to do an EIFS Patch in the middle of the wall and have it look alright is to tape off the area to be repaired in a square block. Do the repair and pull the tape after you run the finish coat. The repair will look nice and square like you planned it to look like that, but this technique will show an obvious patch.
Running the EIFS coast to coast (from stopping point to stopping point) can be very expensive on large walls so it is practical to do the EIFS repairs in many situations.
