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.

Love this product!
This sunscreen is heavy duty, I use it on my boys when we go to beach (They love to spend hours and hours under the blistering sun) and it out performs other brands and has longer protection than their 50 SPF product.

Sun Safe and Satisfied
Living in Arizona, where the sun reigns supreme, finding a reliable sunscreen for my daughter has been paramount. Our spring and summer are filled with swimming lessons, poolside gatherings, and outdoor adventures. In this sun-drenched setting, Coppertone SPF 70 Sunscreen for Kids has become our go-to sun protection.
The standout feature for me is its thick consistency. It’s a parent’s little helper, allowing clear visibility of where the sunscreen is applied to ensure no spot is missed. And the results speak for themselves – my daughter hasn't had a sunburn since we started using it. While she doesn’t have the fairest skin and tends to tan rather than burn, the effectiveness of this sunscreen has been impressive.
I’ve even used it on my own skin, particularly on my shoulders, and I'm happy to report no sunburns there either. It’s reassuring to have a product that I can trust for both myself and my child.
However, I’m aware of the growing concerns regarding certain sunscreen ingredients and their potential health implications. Coppertone SPF 70 contains a mix of chemical sunscreens like Avobenzone, Homosalate, and Oxybenzone. These ingredients have raised questions in recent years. Some studies suggest that chemical sunscreens can be absorbed through the skin and into the bloodstream, leading to potential health risks. Oxybenzone has been under scrutiny for its potential effects on coral reefs and marine life, as well as concerns about hormonal disruption in humans.
While these ingredients have been effective in preventing sunburns for us, I understand the importance of making informed choices, especially when it comes to health and wellness. As with any health-related product, I encourage others to research and decide what’s best for their family, considering both the effectiveness of sun protection and the potential impacts of ingredients.
In conclusion, Coppertone SPF 70 has been a reliable ally in our family's fight against sunburns. It's a product that offers peace of mind when it comes to sun protection, but mindful consideration of its ingredients is advised for those who are concerned about the broader implications of chemical sunscreens.

Amazing how fast it goes on without the white look!
This stuff is amazing!!
I wear baby sunscreen because I rub my eyes a lot, but most of it takes forever to rub in and not look white.
This rubs in immediately like any other sunscreen, and it doesn’t burn my eyes at all, not even when I scratch my face and then rub my eyes.
So it’s great for small children too, not just 75 yr old ones!

Used for years
I have used this sunscreen since my kids were toddlers. I don’t find it sticky and it turns clear pretty fast. I don’t typically need to reapply on them more than once.
