Excellent! Thank you. I have your rtx2000 adapter I just received. Can I glue it on the roof first and cut with jig saw as in this video? 2024 170 sprinter.
Yes. Put a tape line about 1/4" out from perimeter of the adapter. Then spread the beads of sikaflex 221 on the face of the adapter. Press it onto roof and then make a fillet around the perimeter with your finger. Remove tape, wait 22 hours an then cut hole.
You'll want two tubes of Sikaflex 221 and one tube of Dicor per vent. Make sure you clean and de-gloss (scotchbrite pad) the roof and apply 3 continuous beads of adhesive on face of adapter. Do not use alcohol as it inhibits the cure of the adhesive . It helps to warm up the tube of Dicor so it flows better. I usually spread and smooth it out to get a good coat. Apply painters tape around adapter when gluing and sealing to get a clean edge. Remove it right away.
Isn't Sikaflax 521 UV is better for outside and Sikaflax 221 for inside ? Also, where do yo use the Decor ? is that Decor 501LSW-1 Self-Leveling Lap ? Thanks
There are a number of urethane based structural adhesives that are suitable. We have had great results with 221 and always cover it with a membrane or lap sealant like Dicor.
love your videos Hein😎
Glad you like them!
