Tips to follow all year round

1) Regular inspection of openings
2) Top quality caulking joint
It is not easy for individuals to get hold of NP1 professional joint cartridges from Sonneborn, Mulco or ADFAST, if you do the work yourself, do not invest in low-end sealant; buy from the range of “30 year guarantees” minimum.
3) Posing in dry weather and at a pleasant temperature
The silicone gasket is malleable in winter and summer because it is not affected by the temperature, which is why this material is the preferred choice of window caulking professionals.
4) Keep you safe
Working on the last rungs of a ladder is suicidal (do we really need to remind you?)
So use a ladder that is higher than the level of your work, tie it securely to the building.
If you are not equipped in this area or have a problem with high situations, give up the windows on the floor and call the professional.
5) Spending time on cleaning the old joint
6) Importance of the backer rods
Before installing the gasket itself, insert your backer rod flanges into spaces that are too wide or too deep
7) A quality cartridge gun
8) Caulking Gun Flow
For cosmetic seals, pull the trigger on the caulking gun with confidence to promote regular flow. Avoid jerking off and stopping. Exercise beforehand, this double check of the regularity of the flow in places less apparent such as a lintel.
- Pressure on the trigger
- Moving the gun according to the need for filling
9) Filling the joints
10) Smoothing the joints
