Dryvit is one of the largest EIFS manufacturers in the world and they did an excellent job of marketing the EIFS product. In fact they did such a good job that the entire industry was know as Dryvit until recent years. Dryvit did much like Rollerblade® did with inline skates. We now, for the most part, refer to the industry as the EIFS industry, and there are a few manufacturers of the EIFS product, Dryvit being one of them. Each manufacturer of EIFS has there own terminology of the products, so it is a good idea to familiarize yourself with the basic Dryvit lingo. Read more Dryvit ›
The trowel is a very important tool in the EIFS Repair Kit
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.

There are several EIFS finish textures to chose from. The best way to talk about EIFS textures to to be able to see what you are talking about so I will include an image of each teture type.
This is the EIFS Fine Finish which is very popular in the Mid West. The Fine Finish is a smooth finish. And might be considered a high tech look. The finish is applied by a journeyman plasterer with a hawk and trowel and typically floated with 9″ circles by the floater.
This is the EIFS Sahara Finish which is very popular everywhere and is great to cover imperfections in the wall which makes it a perfect match for restorations. The Sahara Finish is not as smooth. And can hide a lot more than fine finish will. The finish is applied by a journeyman plasterer with a hawk and trowel and typically floated with 9″ circles by the floater.
This is the EIFS Coarse Finish which is very popular everywhere and is even better for cover imperfections in the wall which makes it a perfect match for restorations. The Coarse Finish has a traditional stucco look. And can hide a lot more than Sahara finish will. The finish is applied by a journeyman plasterer with a hawk and trowel and typically floated with 12″ figure eights by the floater.
Those are the three main types of finished used in the EIFS industry today. Utilizing a couple different textures on your EIFS project can really make the difference. Using a classic texture on the wall and a fine finish on the detail can really make the difference and add some real class to the job.
I think everyone has there own preference on the consistency of the finish but really if there is too much water added the finish will bleed through and if there is no water added it will tend to roll on you. The best practice is to add a large cup of water like a 24 oz cup. If you are using tint packs with your finish that will give you enough water to make sure you get all the tint out of the tint pack. That is more of an estimate than a solid amount. If it is really hot you could even use 32 oz’s. One of the key things is to make sure you add the same amount to every bucket. I find Senergy, Dryvit and Master Wall all react about the same to the water.
