Sealant Applicators South London Selection: Mastic or Silicone Sealant?

When it comes to windows and door sealants for South London projects, there are a number of unique features which set mastic sealant aside from other alternatives like silicone. As our mastic man in South London knows through his experience, mastic sealants are easy to apply, as they come in a pasta shape which applies to the surface smoothly without need for priming. 

Thanks to our experience with flooring sealant and door sealants in South London properties, we know that mastic is perfect for outdoor sealant application thanks to its ultraviolet (UV) inhibitors, which help keep it from weakening in the sun, as well as its waterproof properties and weather resistance. Unlike some counterparts, mastic sealants are great for use on metals, as they don’t cause corrosion, making them a good choice for external waterproof sealant work across South London. 

Despite its exceptional flexibility, our mastic man in South London does not recommend using certain sealants on areas where it will be subjected to extreme joint movement, as it will eventually wear down. We also advise using mastic for thick sealant applications such as wider cracks in masonry or large gaps, as it’s not best suited for areas requiring a delicate finish.

Mastic Man South London process with Sealant Expert - How to Seal around a Bath?

When it comes to bathroom silicone sealant and bathroom silicone sealant in London homes, our masti man is an expert, waterproofing and repairing kitchens, bathrooms and flooring quickly and efficiently. If you need a mastic man to help with your South London project, to ensure a waterproof seal around your bathroom, contact us today. 

First: Tape the Edges
When it comes to bathroom silicone sealant work in South London homes, using masking tape and around the edge of your bath to mark where you’re going to put the silicone comes first. .Work from the back corner of your bathtub and keep the tape at least 3mm from the wall, that’s our mastic man in South London’s tip. 

Preparing the Sealant
For all bathroom silicone sealant work in your South London property, wear safety, then use your knife to cut the silicone open. Before attaching the head or nozzle of the silicone, cut the tip as close to a 45-degree angle as possible – this will make applying it much easier, then place the silicone into the caulking gun.

Apply the Sealant
Just before embarking on the application stage of your bathroom silicone sealant work at your South London home, get as close to the edge of the bath you want to seal, then apply the silicone by pressing the caulking gun trigger. As our mastic man in South London advises, begin with the furthest corner, ensuring that you don’t touch any new silicone you’ve put down. 

Smooth the Sealant
Our mastic man in South London advises people to use a sealant applicator, a wet round-ended tool such as a wooden spoon, or even a wet fingertip, smooth and shape the sealant edge at an angle. This will help the sealant to shed water back into the tub – particularly if it is a shower bath.

Sealing a Bath with a Large Gap
For bathroom silicone sealant work in South London bathrooms where there is a large gap between your bathtub and the wall, it could be down to poor installation or something preventing it from being positioned – seated – closer. The main action to take will be to remove any silicone or grout that is already there and reseat the bath closer to the wall.

Mastic Man South London for Construction and Renovation


As an experienced mastic company in South London, we know first hand that silicone sealants are often used to seal the border of sinks, showers and bathtubs in a kitchen or bathroom. Our sealant contractors in South London often use them to apply silicone seals between counters and walls. In some cases, our mastic man team in South London use silicone sealants to prevent mold by stopping the advancement of water between surfaces. Our sealant contractors in South London offer sealants in a choice of colours to complement your existing decor. 


Our mastic man team in South London often use silicones developed to easily adhere to building materials such as wood, metal and vinyl. Our sealant contractors in South London appreciate that this feature makes them effective for caulking a building’s doors and windows, with the advantage of increasing the efficiency of a building, stopping unwanted air exchanges between the inside and the outside. Maintaining flexibility over time and across temperatures is a feature of some silicones, used by our mastic man team in South London to protect premises against the elements. 


Some gutters are made from plastic or metal alloys, often used to direct rainwater or snowmelt from the roof away from properties. Our mastic man team in South London know that the drawback is that their permanent exposure to the elements makes their sealing properties weaker. Our sealant contractors in South London know that these seals, between different sections, are particularly vulnerable to wear and leakage. For outdoor projects, our sealant contractors in South London use silicone sealants designed to restore the efficiency of gutter systems, retaining flexibility even at low temperatures and won’t degrade despite exposure to UV rays.


Exterior wall foundations  are often covered with concrete, bricks or stones, construction materials to which few substances can adhere. Thanks to their expertise, our mastic man team in South London know that silicone sealants can overcome this problem, making them  ideal caulk for sealing items such as stove hoods, dryer outlets, outdoor faucets or air intakes that pass through masonry walls.


There are many more applications that silicone sealants are suited to. Contact us today to discuss your project needs with our  expert sealant contractors in South London.
