How to Put Rope Caulk Around a Window
- Mar 20, 2018 -

A poorly-sealed house results in uncomfortable drafts, loss of heat in winter, heating up quickly in summer and allowing in moisture, increasing a home's vulnerability to problems like wood rot, particularly in humid, damp regions. Rope caulk, also known as fingertip caulk, provides a relatively easy, affordable, clean and fast means to seal gaps or cracks around windows, doors and other objects on the structures interior and exterior. The site must be clean and dry for the rope caulk to adhere completely.


1

Brush any loose dirt and debris away from the application site.

2

Clean any grime, sticky or slimy substances off of the application site. Use a cleaning solution or rubbing alcohol and rag to address the grime, if needed. Let the site dry completely before applying rope caulk (glass glue, silicone, silicone sealant).

3

Remove the rope caulk from its packaging. It is typically sold as a roll of ribbon made up of multiple small strips. The strips allow the user to adjust the width of the caulk strip to accommodate varying gap sizes.

4

Measure the length of the gap that requires sealing.

5

Tear off a section of rope caulk to accommodate the measurement. It does not have to be exact as pieces of the pliable, putty-like caulk are easily added or removed whenever necessary. Also, peel the strip apart to achieve two or more thinner pieces. When using more than one strip from the ribbon, twist the material slightly before pressing it in to ensure a more uniform seal.

6

Press the rope caulk into the gaps around and on the window using fingertips, a putty knife or a flathead screwdriver.

7

Rip off and press in the rope caulk until all the gaps on the window are treated.

8

Peel the rope caulk off at the end of the cold or warm season or whenever opening the window, if it is adhered to a movable window part, and store the rope caulk in a sealable plastic bag for later re-use.
