Many people in Nairobi and the surrounding counties come to us when they are putting up a house, running a construction site or setting up a farm. Masterseal 590 (Water Plug) is one of the products in our Building Materials & Steel range. Below you will find what we know about it, how to tell if it suits your space, and a few tips that our customers have found helpful over time. Nothing here is complicated, and it should only take a few minutes.

Keeping it clean

Keep it simple when it comes to cleaning. Gentle soap, warm water and a soft cloth will handle most everyday dirt. Stay away from steel wool and strong acids unless the maker says they are fine. Check the item now and then for loose screws, leaks or wear, depending on what it is. Fixing small issues early is cheaper and saves you from bigger repairs down the line.

Planning your budget

We list prices in Kenya Shillings so you can plan easily. When working out your budget, include labour, any extra accessories and the cost of getting the items to site. If you are buying in bulk for a building project, talk to us about your full list. Note that this page is not a statement about stock, payment terms or delivery, so confirm those details when you order.

Buying in Nairobi

Nairobi keeps growing, with new estates, warehouses and commercial buildings coming up every year from Industrial Area to Mombasa Road, Syokimau and beyond. All this building needs steel, flooring, fencing and site equipment, and that is a big part of what we do. Our showrooms on Homabay Road off Enterprise Road and at Vision Plaza on Mombasa Road are easy to reach. If you are further away, you can still browse online and plan your list.

A quick word on sizes

Sizes matter more than most people think. A product can look perfect in a picture and still be a little too big or too small for your site, wall or floor. So measure twice and buy once, as the old saying goes. If your fundi is around, ask them to take the measurements with you. They will know which points are important for this type of item and can spot problems early.

Where it fits best

Not every product is right for every home, and that is okay. This one belongs to Building Materials & Steel, which gives you an idea of where it is normally used. If you are supplying a big site, you may care more about quantity and a fair price. If it is your own home or farm, you may care more about strength and finish. Decide what matters most to you, then check the listing against that list.

How it will look

A finished job looks neat when the materials go well together. Before you buy, look at the walls, floors and other hardware already in place. Think about whether you want this item to blend in or to stand out. Only rely on the material and finish stated in the description, because something that looks like metal in a photo may be made of something else. When the look is important to you, confirm before you buy.

Fitting it properly

Proper fitting helps any product work well and last longer. If you plan to do it yourself, read any instructions carefully and make sure you have the right tools. If you are hiring a fundi, agree on the work and the cost beforehand. Ask them to check the ground, wall or frame where the item will be used or fixed. A small problem found early is cheaper to fix than one found after the job is done.
