Do not caulk between siding and any built in receiving channels located at or around windows.
Cottage style siding require a gap between them.
Correctly installed siding should also allow air to flow through from top to bottom taking advantage of natural convection to remove moisture.
But when you consider siding don t decide based on looks alone.
Installed properly any siding can deflect water resist rot and block pests.
Batten fasteners pass between gaps in the boards to hold them down yet allowing for natural movement of the siding when installing the wide vertical boards space boards at a distance of approximately one board width 7 8 and secure with fasteners placed at the center of the siding boards.
So you don t get the warping that causes shiplap to look crooked or uneven.
Position the caulk gun so that the angled tip of the nozzle is flat against the gap to be filled.
Depress the trigger on the caulk gun until caulk begins to squeeze out of the nozzle.
These are vulnerable to penetration by driving rain.
Never put a gap on one never seen anyone put a gap on one never gave it any thought but the reasoning for the gap usually on roof shingles is that the shake becomes wet won t dry out and will rot and decay faster without such a gap siding shingles ought not to have that problem.
Drop siding similar to clapboards the top of each horizontally placed board is fitted into a groove in the lower edge of the board on top of it.
To allow for seasonal expansion and contraction a 1 gap is usually left between wider vertical planks.
The tongue actually fits in the groove and once installed on a surface the boards have a gap between them that s about the width of a nickel hence the name.
Narrower 1 x3 strips or battens are nailed over the seams or gaps where the two planks abut to help keep out the elements rodents and insects.
Weigh the difficulty of installation the maintenance needed and the material s durability.
Due to their irregularity shakes virtually always have a few gaps.
The original cottage siding remains a favourite for its looks and sustainability.
Cedar shingles which all share common dimensions can be installed flat with minimal gaps between them.
A felt underlayment is necessary to ensure that shake siding remains watertight.
Vertical trim gap caulking.
Always caulk between the siding and the trim.
Leave a 1 8 gap between the siding and the trim or other materials to allow for structural movement.
Always prime or paint any cut edges that are inserted into a window j channel.
And you often don t have to prime nickel gap either or worry about filling knots.
