All about sealant applicators

Blue half-barrel

The blue half-barrel applicator is an entry level and easy-to-use sealant and adhesive applicator.


It is used to apply low viscosity silicones, sealants and adhesives.


This applicator is not recommended for day-to-day use as it won’t be able to cope with the demands. It is fine for applying sealant around baths, kitchen sinks and in showers every now and then.

Recommended retail price is R 30

Chrome applicator

The chrome applicator is a step up from its blue half-barrel counterpart. Although it looks almost the same as the blue half-barrel, there are some distinct improvements.


Where the blue half-barrel applicator is made from 0.5mm stainless steel, the chrome applicator is made from 1mm stainless steel. You might think half a millimetre can’t make that much difference, but the difference is quite evident when you pick up the chrome applicator.The chrome version is much heavier than the blue half-barrel version and much less flimsy.


The biggest improvement on the chrome version is the plunger, which has a serrated edge for the entire length of the plunger.The serrated edge along with the handle mechanism allows for better control when applying sealants.


Unlike the blue half-barrel version, which has a thumb trigger to release the plunger, the chrome version’s plunger needs to be rotated 180° to enable the release of the plunger.


This applicator is ideal for DIY’ers who need to apply low viscosity silicones, acrylic sealants and adhesives in and around the home on a more regular basis.
