Does Board And Batten Need To Be Caulked?

Board and batten joints require special attention during planning. Gaps can be reliably sealed with lead wool. For craftsmen, there are a few things to consider, especially with connection joints.

Great craftsmanship is often decided on a small scale. Narrow masonry joints represent a challenge for planners and craftsmen. All joints must be permanently protected from the effects of the weather. One possibility for this is with lead wool as a sealing element. This is often used for joints in exposed and heavily weathered areas. These include slopes and unclad window sills. Lead wool is also used in joints, where sheets or overhang strips are inserted into the masonry. Many craftsmen also rely on lead wool for masonry gaps in round arches. The element is suitable for all areas of roof that are difficult to access.

In contrast to mortar, lead wool adapts very well to the movements of other building elements. This is particularly important when connecting to other building materials: because they have different expansions due to weather conditions. The product can be combined with all common types of masonry and construction, from lead, copper to stainless or galvanized steel.

Observe Processing Rules

The correct dimension of the joint is essential for its stability. The following rules have proven themselves in practice: Masonry joints should always be twice as deep as they are wide. The depth of the joint should be at least 2.5 cm. If necessary, the joint should be hollowed out even further.

Executions with lead wool should always be carried out in and, if possible, from a plait. Because: If little board and batten is caulked, it will be difficult to lay another layer. Caulked lead wool has a homogeneous mass that is difficult to install with new threads. In the long run there is a problem of additional layers breaking out of the joint. Therefore, craftsmen should carefully estimate the required amount of lead wool in advance.

Close The Joints Step By Step

In the case of set up, the sheet or the overhang strip is first anchored in the joint and, if imperative, fastened with screws. Then the work with the lead wool begins. In step one, the lead braid is rolled out lengthways. Then the proper quantity of product is picked up and twisted into a strand through hand. The strand is inserted into the joint and evenly pushed into the joint and caulked. A hammer and blunt chisels in more than a few sizes are used as instruments. Some craftsmen additionally use compressed air tools to fill even tight areas.

Finally, the joint surface is smoothed with a chisel. Any protruding filler product or unevenness are reworked with a scraper and, if necessary, caulked again.
