DRY69 is an effective powdered shielding plaster by YSHIELD to be stirred yourself. The plaster is frost-resistant, lighter and therefore ideal for worldwide shipping.
When developing the DRY69 shielding plaster, the focus was on its weight for shipping. For every liquid shielding product (shielding paints), around 50% of what was sent was water. This is obviously very practical as you can start your shielding work as soon as the package is delivered. However, unnecessary water is also sent, which makes it a lot heavier and increases shipping costs. A water supply is normally available. The shipping weight plays a significant role, even in worldwide shipping. Another benefit of shipping powdered shielding plaster is its resistance to frost because there is no water that can be frozen.
The DRY69 shielding plaster is a dispersion silicate plaster with a potassium water glass binder and its synthetic content is under 5%. DRY69 is unique in terms of shielding effectiveness and has the highest attenuation of all of the shielding paints that we have available. Depending on the thickness of the plaster, you can reach up to 60 or even 70 dB. As is the case with all electrically conductive shielding products, the DRY69 shielding plaster must also be grounded. With this grounding, you will be shielded from the low-frequency electric fields. DRY69 is breathable, solvent-free, neutral odor and low-emission.
Convincing properties of the DRY69 shielding plaster
The DRY69 shielding plaster by YSHIELD is best suited to the effective attenuation of stress caused by electrosmog from mobile radiation and electric alternating fields. Radio pollution from cell phones, mobile Internet, WLAN, DECT, GSM, LTE, and many more are attenuated by up to 70 dB, which is an effectiveness of 99.99999%. Electric fields from the power supply (alternating current) are grounded very effectively and can be attenuated by 100% (same as PRO54, HSF54, HSF64, HSF74 and T98).
Even if a thickness of 1 mm would be enough, we recommend putting two layers (2 mm) on to shield from future radio pollution as best as possible. The DRY69 shielding plaster must be grounded!
DRY69 shielding plaster safety warning
DRY69 is highly alkaline (pH: 12) because of the pure use of potassium water glass. Furthermore, because it is made of powder, parts of powder can be swirled into the air when stirring and you can breathe them in. Therefore, the DRY69 shielding plaster can ONLY be used with the appropriate safety equipment. We highly recommend the DRY99 safety set designed for this purpose in the shop.
Features of the DRY69 shielding plaster
- DRY69 does not use any carbon fiber for shielding, which gives even one layer of 1mm-thick plaster equally-good protection in all polarization directions.
- The DRY69 shielding plaster has a relatively high shrinkage of 50% when drying. This is very important to obtain a high screening attenuation. Therefore, the DRY69 shielding paint can only be used on a smooth surface. Unevenness cannot be smoothed with this plaster.
- Always keep in mind: carbon pigments are black and are suited to be used as filler material. Carbon is also expensive. YSHIELD mainly uses expensive carbon in shielding products, which is how they can achieve screening attenuations of 60 to 70 dB. Attenuation values such as those can only be described as SENSATIONAL.
- Highly-effective radio attenuation – screening attenuation: One 1mm-thick layer of DRY69 attenuates by up to 60 dB, 2 layers (2 mm thickness) up to 70 dB. The shielding attenuation is often measured in the EMC laboratory. The measurement setups used follow these standards: ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998, ASTM A698/A698M-07.
- Delivered as powder to be stirred yourself
- Low shipping weight because of the lack of water
- Frost-resistance for shipping because it is delivered without water
- Year-long shelf life
- Substrate: We recommend pretreating the substrate with our GK5 primer concentrate or another primer. Excellent adhesion to almost all absorbent substrates. Not usable on gypsum-based substrates, the potassium water glass cracks the gypsum!
- Final coating: Sand down any elevations or ridges as normal. Generally, only organic dispersion paints or silicates adhere to graphite layers. For purely mineral coatings, we recommend our GK5 primer concentrate or another primer is that is usable on the coating. Do not use any gypsum-based coatings, potassium water glass cracks the gypsum!
- Earth: Must be grounded! We recommended the self-adhesive grounding tape for indoor use.
Yield of the DRY69 shielding plaster
Generally speaking, the yield of a shielding paint is necessary depending on the surface. For the best results, the substrate must be prepared and flat. We generally recommend using our GK5 primer concentrate on the flat substrate or a primer that is suitable for that substrate. The “average” yield is therefore based on an “unideal” substrate.
- ONE LAYER COATING: 1mm thickness up to 20 m² per container (1 m²/L)
- DOUBLE-LAYER COATING: 2 mm thickness up to 10 m² per container (0.5 m²/L)
DRY69 shielding plaster is preferably used indoors. DRY69 is suited to outdoor use as well thanks to its moisture resistance. Preparing the shielding paint takes approx. 70 minutes. A container contains 12 kg of shielding powder and is mixed in a bucket with 12 liters of water. Stirring the plaster can only be done with suitable painting equipment. Stirring by hand is impossible and leads to a lumpy shielding plaster that does not provide good protection and may not be applicableGK5 primer

Mandatory grounding of the DRY69 shielding plaster
All electrically conductive surfaces must be grounded by a qualified electrician in accordance to the DIN/VDE regulations. This can be done over the electrical system’s grounding support (ground contact in the socket) or on the grounded heating pipe of the wall heaters (radiator). A protective circuit also needs to be installed in the fuse box. It must be noted that the circuit must be turned off before painting – a 230-volt, 16-amp shock can be deadly! The electrified flush-mounted box must be a centimeter away when painting the wall.
Electrical alternating fields can be grounded, contrary to mobile radiations (high-frequency) which are based on reflection and cannot be grounded as a result. A protection against mobile radiation is also based on reflection whereby the electromagnetic radiation is prevented from entering the room.
