EIFS Moisture Testing

EIFS repair and EIFS moisture testing goes hand in hand

I think it is about time we included EIFS moisture testing as a service in our everyday services, as it only makes sense to find out where the moisture is and where it came from before we even start any repairs. Till this point we had been calling in 3rd party inspectors and waiting for the results and then taking over from there and correcting all their findings anyway. The truth of the matter is that you really cannot simply read a book, go out and buy an expensive moisture EIFS Moisture Testingmeter and think you are going to be proficient at finding moisture behind the synthetic stucco. It takes years of particle experience in the field. We have been applying Exterior Insulation and Finish System for over 27 years and have been focused on synthetic stucco repairs full time for over 5 years. There is absolutely no one more qualified to do your Exterior Insulation and Finish System moisture test, bottom line. Knowing where to look for moisture intrusion and what to look for is half the battle, but water is a funny thing. I have seen on numerous occasions water infiltrating the the system from one area and running down a metal stud or I-beam up to 30 or 40 feet away and causing damage. The usual suspects for moisture intrusion are other products not the synthetic stucco itself. The flashing will fail or was not done right in the first place or the caulking will begin to crack and let moisture in around the doors and windows. Whether, the roof copping or the sealant failed it is usually due to one of two things someone didn’t do it right to begin with or someone did not maintain it for years. We have done a ton of repairs over the years and we have seen it all. We know exactly what the problem is as soon as we look at it nine times out of ten. Just knowing there is moisture behind the wall and what the percentage reading from a meter is, is really not good enough to begin the repairs or even estimate how much it is going to cost to fix it. You have to know where the moisture came from and how you are going to prevent it from returning. For this reason we carry a moisture reader with us on all our repair jobs. Moisture testing goes hand in hand with a visual inspection. Having the equipment is a great help in determining the problems but there is nothing that can replace 28 years of hands on experience. A good EIFS inspection utilizes testing equipment and years of experience in the field.  

EIFS (Exterior Insulation and Finish System) is also known as Dryvit™ or Synthetic Stucco.

EIFS Sealant

EIFS Sealant

Use an approved EIFS Sealant when caulking Synthetic Stucco

A low modulus approved Sealant is used as a weather sealant in order to seal joints. This sealant is used in order to have the best paint-ability where painting is required. A durable watertight, flexible seal will form and the adhesion to EIFS and other porous surfaces is reflected in an outstanding curb appeal for your building. Dryvit or any premium primer will be acceptable in order to ensure proper adhesion to EIF System and other porous surfaces such as masonry surfaces.  The Spectrem line is recommended for use on new and remedial construction as a weather seal.  Sealant may be used for restoration as well as repairs.  It can be easily painted over with great results using an EIFS manufacturer paint product.  Dryvit offers a sealant that at 50% compression at 70 degrees c (158 degrees f) on limestone, brick, concrete as well as concrete showed no stains after 14 days.  Your Exterior Insulation and Finish System surface must be free of any foreign substances such as water, frost, grease or oil and including old sealant, dirt and efflorescence   A base coat of primer should be used.  EIFS Caulking and SealantsIn order to have a warranty for your Exterior Insulation and Finish System sealant from Dryvit a field adhesion test shall be utilized by the contractor in order to verify the adhesion characteristics as well as the compatibility with the specific materials you are using as an Synthetic Stucco sealant.  You may follow Dryvit’s Field Adhesion Test Procedure with the results being submitted to Dryvit’s Warranty Department.You may apply the  primer full strength with a brush or a roller.  Applying a thin coat that is uniform and no more than 1 mil when wet.  You do not want to over apply the sealant although some very porous surfaces may require a second coat.  The primer must be dry before applying the sealant.  It should take the primer about 15-30 minutes.  You must do the priming and sealing on the same day. If the sealant is not applied on the same day you would have to reprime.  Metal and such non-porous surfaces must be clean and rust free.  You may use a solvent to clean it with which is available at most sealant / building supply houses.

EIFS Repair Tip Of The Day for 3-20-2011

Repairing EIFS | Exterior Insulation and Finish System

There are two ways to repair Synthetic Stucco, one is to patch the damaged area only and the other is to repair from coast-to-coast. What I mean by coast-to-coast is from corner to corner or V groove to V groove. When you repair an entire area coast-to-coast, it is much easier to make it look like new again. When you patch an area in the middle of the wall without going coast-to-coast it is near impossible to make it look new again. You will always see the patch no matter what you do.  So, best practice is to go coast-to-coast with all your Exterior Insulation and Finish System repairs. Matching the color exactly is very difficult as well. After you finish your jobs you should always leave the owner some of the color so they can match it for repairs down the road. Architects and owners should keep in mind when designing that if repairs are to be done latter you will not want to redo entire walls for small repairs and add V grooves to the design. V-grooves can break the wall up into more manageable and cost effective areas to repair if and when the time comes.
