Window and door frame caulking (internal and external)

Caulking to internal and external window and door frames can solve many problems before they arise. Examples of such problems include water leaks, bugs and insects, cold drafts, gaps and can also improve overall aesthetics. 

Cabinetry caulking

Caulking to cabinetry can be undertaken for both aesthetic and functionality purposes. Aesthetically it can finish off a project and make it look complete. Functionally it can assist in removing gaps and hiding any uneven joinery. 

Flooring caulking

Caulking can be applied to a variety of flooring types, including skirting boards, tiles, polished concrete, epoxy floors, amongst many more. Although not always a requirement, it can assist in aesthetically finishing off the project. Caulking to flooring can also assist with hiding gaps, preventing insects, and preventing mop water or accidental spills from getting underneath the flooring.

Wet areas (bathrooms, kitchens and laundries)

Previously entire wet areas would be grouted by the tiler, a product which has no movement and flex, and would unfortunately crack over time and use. Today silicone is the number one product for these areas. Silicone allows for movement and flex, waterproofs the joints (preventing leaks and major water issues) and also comes in a variety of colours to match any room. Other items that should be caulked in wet areas include toilets, urinals, basins, sinks, mirrors, shower grates and shower screens to minimise future water issues. 

Alucobond panels and cladding

Alucobond panels and cladding usually experience high movement rates and flex, and are exposed to the elements and unstable temperatures. Therefore it is extremely important that these areas are caulked by a professional with the correct knowledge, skills and most importantly products. Generally cladding is used as features on projects, therefore they must also look uniform and neat. 

Precast panels

Due to the way precast and tilt panels are erected, the type of caulking required generally depends on its location. Most internal precast panels use a 4-hour acrylic, whilst most external precast panels use a 4-hour fire rated polyurethane adhesive. The panels must be caulked due to the large gaps between them. 

External caulking (brickwork and render)

External caulking is used to join two surfaces that are generally not of the same material (example: a brick wall to render). This is undertaken to allow movement, seal gaps and to prevent damage from shifting or settling.  

Expansion joints

Expansion joints are used to relieve building movement stress, generally caused by temperature changes, sway and seismic events. Pavers, concrete, brick and masonry work on structures all have these expansion joints. Depending on the purpose and finish, different types of sealant can be used.    

Fire rated caulking

Fire and smoke damage can leave a building beyond repair, therefore fire rated caulking is one of the best forms of passive fire protection. Fire rated sealant helps to minimise the potential damage by limiting the fire or smoke to one area of the building. Fire rated sealants work effectively as a fire retardant between ceilings, beams and joints, and to stop fires from spreading further.   

Swimming pool caulking

Caulking should always be applied to swimming pools, spas, paving around swimming pools, and to any outdoor areas with high exposure to moisture. The sealant used should be extremely resistant to water, chlorine, fungus and the elements. NKA Caulking can provide the correct advice and materials for this. 

Caulking work at heights

Working at heights is one of the highest risk activities that can be undertaken in the construction industry. Whether this be working in a scissor lift or boom, working on scaffolding or working on an extension ladder, NKA Caulking has all the required tickets and safety measures to perform the job safely and efficiently.
