Sealocrete products are widely used in construction and renovation.
This site provides clear information about what they do, how they work,
and what to keep in mind when using them.

Concrete and
repair mortar

A typical concrete mix follows a 1:2:3 ratio—1 part cement, 2 parts sand, 3 parts gravel. This gives a balanced blend of strength and workability for most construction tasks.

70%

Curing time

Concrete usually takes about 28 days to reach full strength. After 7 days, it gains roughly 70% of its final strength, which is often strong enough for light use.

10 mm

Layer thickness

For repair mortars, a minimum thickness of 10 mm is recommended. Thinner layers may not bond well, especially on uneven or dusty surfaces.

Bonding agents

Repair mortars often need a bonding agent if applied over old concrete. These help improve adhesion and reduce the chance of cracks.

Surface prep

Before applying mortar, clean the surface thoroughly. Remove dust, oil, and loose debris for proper bonding and long-term durability.

Mixing tips

Always add water gradually. Using too much water weakens the mix. For consistent results, use a mixing paddle at low speed for 2–3 minutes.

Sealants and caulks

Sealants are used to close gaps and keep moisture out—especially around windows, doors, baths, and roofs. Choosing the right type and applying it correctly makes a big difference in how long it lasts and how well it works.

Application tips

Clean the joint, apply tape to get neat lines, then use a steady squeeze and smooth the bead with a wet finger or tool. Work in sections no longer than 1 meter to keep control over the finish.

Type matters

Silicone is flexible and waterproof, ideal for bathrooms and kitchens. Acrylic is easier to paint and often used around interior frames. Choose based on movement, exposure to water, and whether you need to paint over it.

 

Drying time

Most sealants skin over in 5 to 20 minutes, but full curing may take up to 24 hours. Silicone generally cures faster than acrylic. Avoid contact with water or dust during this period.

Cleaners for stone and concrete

Stone and concrete attract dirt, algae, and cement residue over time. Using the right cleaner helps restore the original look without damaging the surface. Acid-based cleaners are strong, but must be used with care.

Use acid cleaners for stubborn stains like mortar haze or limescale. Never use them on limestone or polished surfaces—they can etch or dull the finish.
When to use
Always dilute according to the instructions usually 1 part cleaner to 10 parts water. Wear gloves and goggles, and rinse well after use to neutralize the surface.
Safe use

Outdoor surface protection

Outdoor surfaces like paving, brick, and concrete are exposed to rain, frost, dirt, and sunlight. A sealer forms a barrier that helps reduce wear, stains, and water damage.

Water barrier

A penetrating sealer helps keep water out while allowing the surface to breathe. This lowers the chance of frost damage and algae growth.

Color boost

Some sealers slightly darken stone or concrete, enhancing the natural color. Always test on a small area first to see the effect.

Easy cleaning

Sealed surfaces are easier to sweep and rinse. Dirt stays more on the surface instead of getting deep into the material.

Reapply time

Most sealers need reapplying every 2 to 4 years. Traffic, weather, and product type affect how long the protection lasts.
