We want you to get the best result from your resin floor.
We have created the following overview and our supporting technical materials, not just to support you as you install this kit, but also to keep you safe. You must ensure you read, understand and follow our Health and Safety data sheets and our Technical data and installation guide. If you have any questions, call us before you start, we’re here to help.
Who can typically install this resin kit?
We have designed this kit to be suitable for semi-skilled installers to use. Installing a resin floor is very different from installing a vinyl sheet or LVTs, so if you feel you lack the right experience to install this product and can benefit from professional help, please get in touch to discuss this with us.
Substrate requirements
Important: on substrates that are liable to direct hydrostatic pressure eg some basements, low-lying buildings, or in the absence of an integral DPM, a more substantial installation may be required.
Your substrates should be dry, structurally sound and free from contamination, friable materials or laitance, which may affect either the adhesion or penetration of Altro Proof Standard. You must mechanically remove all residues of old paint coatings and dust to achieve maximum adhesion. Substrates should achieve 26N/mm2 compressive strength and 1.5N/mm2 surface tensile strength.
Building Regulations
New ground-supported concrete should incorporate an integral, physical and functioning DPM within the construction in accordance with building regulations.
British Standards
Concrete floors must be constructed in accordance with British Standards BS82004 part 1: 2008.
The slab should be a minimum of 21 days old. Using a hygrometer in accordance with BS 8203:2001, measure and record the moisture: it should have relative humidity up to a maximum of 97%.
Surface preparation
Prepare the surface of the substrate with a dust enclosed diamond floor grinder, or lightly shot blast it, to leave a textured surface free from contamination. If the floor has been treated with a cementitious surface improver, prepare the surface following the manufacturer’s recommendations or abrade with a rotary floor preparation machine, followed by thorough vacuuming. Carry out any local repairs, treatment of cracks and holes, improvement or modification of levels and removal of high spots before installation.
Installation conditions
Apply in well-ventilated areas only, at a temperature between 15 °C and 25 °C. Ambient conditions should be maintained at least 3 °C above dew point or below 75% RH during initial stages of cure.
Mixing equipment
You will need:
- Slow speed drill (200-500rpm) such as MM17*
- Mixing paddle such as MR2 60B*
*All tool number references relate to Refina Ltd. Call to order on 01202 632 270.
Cleaning
Clean all tools and equipment regularly during installation.
Personal Protection equipment (PPE)
Ensure that you wear the correct PPE at all times.
Product installation
Using a slow speed drill and paddle thoroughly mix the base colour for 30 seconds. Pour all of the hardener into the pre-mixed base and mix for a further 4-5 minutes. Ensure you fully mix the material around the sides and bottom of the container; avoid vigorous mixing as this can lead to bubbles and pinholes.
Immediately pour all of the mixed material onto the floor in a ribbon. Use a 2mm x 5mm notched trowel or dense foam rubber squeegee to distribute the material evenly, then use a low-loss medium pile synthetic roller that you have pre-wetted with Altro Proof Standard to uniformly and fully treat the surface.
Allow to cure and carefully inspect the applied film for defects, such as pinholes and areas of under-thickness. If necessary, apply further Altro Proof Standard locally on these. Allow curing for the minimum overlayment period, before you apply either a water-resistant levelling screed or the floor covering, using a suitable water-resistant adhesive.
Full cure
You should achieve full cure in 7 days at 20 °C. Untreated felt paper is sufficient as protection from light traffic.
Your completed installation
In general, flooring will follow the profile of the underlying substrate. Please note thin coatings will reflect the surface texture.
