ACRYTOP Deep Seal – Durable, Fast-Curing Cement Modifier
ACRYTOP Deep Seal is a high-strength acrylic cement modifier. An advantage of using Deep Seal is that it cures quickly, making a hard, tough, and durable patch. Deep Patch does not contain asbestos, lead, or mercury. Topfloor Sports Infra recommends Deep Seal for a wide range of surface repair applications. Basic Uses: Deep Seal is designed for mixing with Portland cement and sand. It can be used over new or existing asphalt or concrete recreational surfaces. Deep Seal can also be used to fill cracks and will not sink like elastomeric crack fillers.
Always wear the recommended personal protective equipment. Avoid contact with eyes, skin, and clothing.
ACRYTOP Deep seal should be kept dry and cool. Storage temperature should be between 4°C (40°F) and 32°C (90°F). Packaging: 50 kgs/drum) or 20 kgs/ drum
The surface upon which Deep seal is to be applied must be free of dirt, loose and flaking paint, vegetation, chemical or oily residues or any other substances that might inhibit good adhesion. Mechanically roughening the area will aid in adhesion, and should be done if the area is too smooth.
Do not mix more material than can be placed in 15 minutes. A trowel or straight edge should be used to apply material. Should the material become stiff while working, dip tool in clean water for easier working. Edges of the patch should always be “feathered” so there is a smooth transition at the edge of the patch.
It is sometimes necessary to use a coat of Acrylic Resurfacer mix to blend in the patch. Patches filled with Deep seal must be allowed to thoroughly cure prior to applying the next coating application. Cure time depends on the depth of the patch, and may take up to 24 hours.
Mixing Ratio
This mixing ratio will help you understand which ingredients to use and in what quantities. You can watch this video to see how they make a deep seal.
| Mixing Ratio | |
| Acrytop Deep Seal | 20KG |
| Water | 1 Liter |
| Silica Sand | 55KG |
| Cement | 20KG |
Coverage
For thin patches of 3/8″ or less: Premix 5 gallons dry, 90 mesh silica sand with 1 gallon of Type 1 Portland Cement. Add 2-3 gallons of Deep Patch, and mix thoroughly with a mechanical mixer. For patches ¾” or less: Premix 5 gallons dry, 60 mesh silica sand with 1 gallon of Type 1 Portland Cement. Add 2-3 gallons of Deep Seal, and mix thoroughly with a mechanical mixer. For patches greater than 3/4″: Patch in successive lifts, each no greater than ¾”. Follow the previous mixing instructions, and leave the first coat in a rough condition to provide an additional mechanical bond. It is imperative that each coat is fully cured prior to application of the second coat.
Limitations
- Do not apply when surface temperature exceeds 130°F (54°C).
- Do not apply when temperatures are below 50°F (10°C) or when rain is imminent.
- Do not use calcium chloride or calcium chloride-based mixtures in Deep Seal.
- Drying time depends on the weather and patch thickness.
- DO NOT ADD WATER. Adjust the viscosity by adding more Deep Seal.
- Fresh hot mix asphalt surfaces continue to move for several months, and any acrylic-modified concrete patch may have a tendency to crack as the substrate moves.
- If you experience white staining over the patched area, you are probably using too much concrete in the mix.
