CHOOSE THE RIGHT SEALANT

Too often, the contractor or installer will depend

on past experience with a specific sealant

regardless of the requirements.

“It always

worked before – I never had any problem

with this material”.

Well, this is a sure way to

get in trouble! Most contractors and applicators

do not have the technical knowledge to make the

decision on the proper products to be installed in

order to meet all requirements. However, they do

know what is expected from a sealant under

specific conditions.

The input from the manufacturers is critical.

After all, they are the ones you are going to call

if your sealant fails. When you call them, be

precise and truthful. Manufacturers cannot help

you unless you give them the proper

information:

1. Joint design and size.

2. Substrate (concrete, stone, metal, etc.)

3. Condition of the substrate.

4. Geographic location and weather

conditions.

5. Expected performance from the sealant.

6. Your experience doing these types of

projects.

7. Are they willing to warranty their

sealants?

8. Then you can ask the price.

Generally, the contractor does not get the credit

for the success of a sealant, but will get the

blame if it fails.
