Why We Love It

Natural ingredients ensure safety.
Exceptional durability under harsh conditions.
Invisible protection for historic surfaces.

Main Highlights

A natural sealer - water-based, eco-friendly, invisible, and ultra-thin (nano-sized) water & oil repellent (hydrophobic & oleophobic), optimally designed for use on absorbent and porous surfaces.
Assists in retarding corrosion, disintegration and destruction of the coated surface for an extended period of time also under harsh environmental conditions of humidity, sea and saline humidity, and so on.
Hydrophobic - self-cleaning effect (while raining ), UV stability, greatly improves the resistance to erosion and disintegration, as well as durable under harsh conditions. Nano-Stone ST protects and preserves as new, the initial textural properties for a longer lifespan
Extraordinarily stable UV durability and resistant to high environmental temperatures. Other existing products based on silicone, oils and fluorocarbons disintegrate and disappear in sunlight and solar radiation within a relatively brief period of time.
Prevent rain damage around the building/house - facades and in places suffering from rain damage. The "invisible" effect makes it excellent for use in historic buildings such as churches, museums, etc. For use on natural stone, concrete, marble, plaster, clay, stucco, sandstone, limestone, granite, cement board, terra cotta as well as on any natural porous mineral surfaces

Nanotech Surface Solutions

Nanotech Surface Solutions Ultimate Sealant - Water Repellent, Penetrative Natural Look Sealer - for Concrete, Pavers, Clay, Stone, Masonry - Easy to Use - Fast Curing, 1 Quart (32 Oz.)

Why We Love It

Completely invisible.
SiO2 nano-based composition.
Easy to apply.

Main Highlights

COMPLETELY INVISIBLE FINISH. Ultimate Sealant is a water-based penetrative coating for porous substrates such as concrete, clay, limestone, sandstone, flagstone, cantera, masonry, etc. that does not alter the appearance or texture of treated substrates.
SIO2 NANO-BASED COMPOSITION. Instead of using conventional silanes/ siloxanes, Ultimate Sealant uses silicon dioxide nano particles that are able to bond with the substrate on a molecular level and offer longer-lasting UV ray and water repellent protection.
EASY-TO-APPLY. Forget about applying a milky white looking liquid on your vertical/ horizontal surfaces that might end up leaving residues once it dries. Ultimate Sealant is odorless, colorless and can be sprayed, rolled, or brushed into almost every absorbent substrate.
GREAT AREA COVERAGE. Each gallon can cover up to 450 sq. ft. on the first coat and even more on the second coat. It usually takes two coats for the substrate to develop an outstanding water repellent protection.
LONG LASTING PROTECTION. Ultimate Sealant will offer a water repellent protection for more than 8 years on vertical surfaces. Due to the nature of its chemical composition, UV rays will not degrade it the way it degrades silanes and siloxanes, making it more resistant and longer-lasting than conventional sealers.

Aquaforest Stone Fix 6000g

Main Highlights

Quick grip glue based on cement intended to combine large elements of live rock and ceramic. It has no toxic compounds so it is completely safe for fish and invertebrates.
How to use: Mix a small amount of glue with water until a uniform consistency and plastic is obtained. Immediately begin to merge the elements. We recommend "dry" gluing.
In case of need to glue in water, turn off all the circulation and recirculation pumps, glue the individual elements and leave it in place for about 15 minutes.
A temporary turbidity of water is not normal and is not harmful.
In crowded tanks we recommend not to glue more than 2-3 items per day as the resulting deposit may slightly increase the pH value in the aquarium.

HOW TO USE: Our waterproof paint sealant can be used in just a few quick and easy steps: Firstly, shake well before use, then apply a generous, even coat with a brush, roller or garden spray. For more porous surfaces, apply a second coat of our damp proof paint whilst the surface is still damp. Finally, allow the sealer to cure overnight and expect optimum performance to be reached after 2-3 days.
LONG LASTING PROTECTION: A 5 litre tub of our liquid water sealant forms a long-lasting barrier that covers up to 25m² based on one coat, depending on surface porosity.
