About this deal

Mastic sealant is used in shower cubicles to prevent water from seeping into places it should not. You might need to replace the sealant if it starts to peel off due to improper application or becomes moldy. You should ensure that the material where you are to remove the old mastic sealant is dry, as this will make it easier to pull it away from the surface. You can use a blade or scraper to get rid of the old seal, but you have to exercise caution to avoid damaging the walls or sink. You may need to use cleaning products to help get rid of hard to remove bits. It is essential to ensure that such cleaning solutions are suitable for the surface you are working on, more so when dealing with more than one material, like tile and plastic. A heat gun or hairdryer can also be used to loosen the sealant. Commercial flooring contractors working with concrete will have floor sanders and floor grinders at their disposal. There are also floor grinding attachments that can be used with floor buffers or auto scrubbers. You'll want to work in small sections to keep yourself safe from burns. Put a small pot of water on the stove or in an electric kettle and pour the boiled water on a select area. Make sure you're pouring the water very close to the floor so that you don't get burns from splashes.

Fill the bath with cold water up to the halfway point. This is ESSENTIAL if you have a flimsy plastic bath that flexes. If you don’t do this, when you go to fill the bath for the first time, the mastic may tear or split as the bath flexes under the weight of all the water. Before you begin the job, you should be aware that removing mastic can be dangerous. If the carpet you are pulling up is older than the 1980s, there's a good chance that the mastic has asbestos. In that case, you must take the appropriate measures to contain the hazardous material and protect your health.

The Dangers of Removing Mastic

Acetone is flammable and gives off toxic fumes, so handle with care. Unlike ammonia, you don't have to mix acetone with water. Instead, pour acetone into a tray for dipping your coarse bristle brush.

If elbow grease and heat weren't enough to pull up the mastic, you might need to resort to chemicals. Make sure you are equipped with goggles, gloves, and masks so that you are safe from chemical splashes, fumes, and burns. Much like riding a lawnmower, you can ride a concrete floor grinder. This type of concrete grinder is great for larger projects. Their blades can grind down several feet of the floor at a time, making for a more efficient tool. Similar to the boiling water method, the ironing method applies heat to the glue. The hope is that the heat will make the glue gum up and be easier to scrape off.For general-purpose sanitary sealing such as baths, sinks and shower units, Dow Corning 785 is a great option. I bought this after seeing Charlie DIYte raving about it on his YouTube video. I already have a Fugenboy tool which is similar to this that I was pleased with that but could see the extra advantages of this Cramer tool set whilst watching the video. The guide to span the tile grout lines is particularly useful. Extremely competitively priced at Plumbworld. A must have for a very professional finish. Various profiles and sizes. Results were remarkable!
