An EIFS Applicator relies on his Paint Brush when doing repairs to feature the EIFS material into the existing wall.
EIFS Repairs and your paint brush explained by an EIFS Applicator
A good EIFS Applicator knows your paint brush is used in just about every EIFS repair or patch. I always feather the base coat and finish coat into the existing EIFS material to obtain a smooth transition from the repair to the existing wall. The one major down fall of EIFS repair is they can been seen in certain light and at times can really look pretty bad. And it can be that the person doing the repair does not know what they are doing or that they did not take the time to get it right. But even when a professional takes his time and everything is done right it can still look pretty bad in the right sun light. One of the most important ways to make sure you are going to make your EIFS patch look it’s best is to feather out the base coat and the finish coat so it is a seamless transition from the patch to the existing EIFS. When using you paint brush you want to brush out away from the patch. The goal is to take away the edge of cement and feather it out. To explain further, we taped off the area when it is ready for base coat and apply the cement mix to the patch. Then pull the tape off and you have a perfectly square patch. Now, you will apply another round of tape about 1 -2 inches from your perfectly square EIFS patch. Take take your paint brush and feather the edge of the EIFS material out to the new round of tape. This will still give you a nice square professional looking patch but very smooth and it will be much harder to see the transition from the existing EIFS to your patch. When you do the Finish coat I like to do the same thing. Keep in mind that you only have so long to work with the finish before it starts to dry and if you continue to mess with the finish coat after it begins to dry you will burn it. Which means you have continued to float the finish after it has begun to dry and that really looks bad and there is really no way to fix it besides letting it dry and doing it again. So, be careful when doing the finish coat. Note: If is 90 degrees and you are doing a patch in the direct sun do not even try to do the second layer of tape.
