- Remedy for Leaks
Coprox Waterproof Cement Additive is an excellent primary waterproofing when mixed with mortar, screed, unreinforced concrete or plaster.
It is an essential ingredient in the construction of structural, retaining and boundary walls, floors, showers, basements, wine cellars, underground parking, ponds, swimming pools, reservoirs and water features for the prevention of rising, falling and penetrating damp.
Coprox Waterproof Cement Additive is also an excellent remedy for the plugging of leaks.
Primary Waterproofing
- Add 2,5 kg Coprox Waterproof Cement Additive to every 50 kg of cement used in any mortar, screed, concrete or plaster mix.
- Ensure recognized building mix ratios are adhered to.
- Mix dry ingredients thoroughly.
- Add required quantity of water to the dry mixture using recognized building mix standards.
- Mix wet ingredients thoroughly before use.
Plugging Leaks
- Dovetail the leaking spot with a chisel to a depth of about 50 mm and clean thoroughly.
- Mix one part Coprox Waterproof Cement Additive with two parts of clean fine plaster or silica sand by volume, e.g. 1 cup Coprox Waterproof Cement Additive to 2 cups sand. Add a little water and mix until a putty like consistency is achieved.
- Wear protective gloves and knead well for about half-a-minute.
- Relieve the main water flow by inserting a piece of hose into the dovetailed cavity.
- Pack the plugging mixture firmly around the hose to keep it in place.
- Level the plugging mixture with the surrounding surface.
- Allow to dry for approximately 1 hour.
- Mix a fresh quantity of plugging mixture.
- Have a dowel stick approximately the same diameter as the hose ready for use.
- Carefully remove the hose using a twisting motion.
- Force the plugging mixture into the hole and apply pressure with the dowel stick for about 1 – 2 minutes.
- Remove the dowel stick.
- Fill the remaining void with the plugging mixture.
- Allow to dry for approximately 2 hours.
- Apply two coats of Coprox Masonry Waterproofing.

Protect Your iPad
Color: Tea Brown, Color: Tea Brown
Perfect case for my iPad! I love the leather feel of the case especially for professional work settings. The exterior pocket is helpful to hold business cards or any document. I’ve had no problems with the case. The magnetic component keeps my tablet secure and the tablet stays in place when adjusting it. The keyboard connects via Bluetooth and I love that it has different colors to choose from. The light does not stay on the entire time, but it has a button to click on when you need the keyboard backlight on.
I don’t use my iPad frequently but this case gets the job done. I always take it with me on flights without an issue and my tablet is always protected.

Affordable and Stylish Folio
Color: Blossom
Things to note: They keyboard requires charging. The keyboard is loose in the folio. For some reason I assumed it was attached. It's not unusable but a little tricky. I would have preferred it anchored into the folio. The folio itself self is lovely and well made. The keyboard feels like I better baby it or one wrong move and I might end it. I wouldn’t recommend it for heavy handers but I do appreciate the feel and lightness. I do wish I had listened to my husband and sprung for a pricier model with pass through charging but for the budget I feel I’ve gotten a good deal on a very elegant looking and functioning case.
